Week 18: New Song “Mr. Jones” – Acoustic

Here’s a new track I wrote last week called Mr. Jones. I’ve actually had the chorus floating around for a few years, but never fleshed it out. I’m glad I finally did!

Year’s End

Well, I had hoped that I’d get back into this fast enough after slipping off to be able to catch up and get to the full 52 posts before year’s end, but clearly that didn’t happen. I do, however, have a handful of projects I’ve done but haven’t yet posted, so I’ll have a few more before then. Either way, I’ll be continuing on with Weekly Creations into the new year.

So until next time, much love and creativity!

Week 16: Tutorial – How To Make Sound Absorption Acoustical Panels

Featured

This week I’m going to show you how to make the sound absorption acoustical panels I made for the studio a few months ago and wrote about in this post, which elaborates on the use and effectiveness of such panels.

I now have a small side business making these panels for others, using industry standard materials that look and perform beautifully. But today I’m going to give a tutorial on how to use less expensive materials in a way that will allow you to make some panels for yourself that still look great and are just as effective for controlling sound as the pro panels, at roughly half the price.

Now of course, professional panels are constructed well, are easy to install, and always come out looking top-notch because they’re made by people who with experience and with materials and processes that are paid for in bulk. But in all reality, they are fairly simple to build. So if you’re a little handy, have extra time and want to save a couple bucks, here’s how you do it!

And if you’d prefer, you can easily purchase professionally made panels at a guaranteed low price from the Inity Acoustics website.

Tools and Materials

First, let’s look at the necessary tools and materials. The tools you’ll need are fairly standard. Of course, if you have better tools you can save yourself a lot of time with some steps. But I’ll show you how to make these using tools many people already have at their disposal.

Tools:

Materials:

I’m going to list the materials needed to make 8 panels. I picked 8 because the sound absorption insulation I’m recommending comes in packages of 8. Here’s what you need.

  • Sound absorption core material. Recommended: Roxul Safe’n'Sound (3″ thick, 2′x4′ for wood studs, 24″ on center) – 1 package of 8 (Other options listed below. Compare noise reduction coefficients of various materials here.)
  • 1×3 framing lumber (8′ lengths) – 12 pieces (make sure they’re straight!)
  • 1/4″ sheets of plywood (4′x8′) – 2 sheets – get these cut to 2′x4′ pieces at the store (or have them cut 1/16″ less than 2′ width to compensate for saw blade thickness)
  • Carpenter’s Glue – 1 bottle
  • Fabric to wrap around the panel (minimum 56″ width) – 8 yards
  • Spray Adhesive (optional) – 1 can
  • Staples (3/8″ or 5/16″ or so) – 1 package
  • Screws (wood, #10 x 1-1/2″) – 1 pack of 100
  • Finishing nails (1″ or so) – 1 pack
  • If you have a nailer, replace the screws and finishing nails with 1 package of brad nails (1″)
  • Hanging Hardware – Options include D Rings with Picture Hooks, Z-clips, or other picture hangers.

Sound Absorption Core Material

There are other options you can use for this. There’s a material known as Owens Corning 703, that has a history of use in many studios around the world. It is the name brand for this kind of thing. Over the years, many companies have developed similar products, and pricing has become far more competitive. The acoustical properties for the Roxul material is nearly identical to Owens Corning products, but at a low fraction of the cost. If Roxul Safe & Sound is not available at your local building supplies outlet, there are a few other options. Here’s a list of some materials, and their approximate pricing:

  • Roxul Safe’n'Sound – 3″ thick – $0.69/sqft
  • Roxul RHT 80 – 2″ thick – $1.24/sqft (may be able to find it for less)
  • Owens Corning 703 – 2″ thick – $2.13/sqft (difficult to find in Canada)
  • Johns Manville 817 – 2″ thick – $1.60/sqft (minimum)

Here’s a great site for comparing the sound absorption coefficients (the amount of sound absorbed at particular frequencies). You can see that these products have roughly the same effectiveness in absorbing sound over multiple frequencies. The Roxul Safe’n'Sound is definitely the best bang for your buck, and you can find it any Home Depot. Can’t go wrong! If you can’t get it as easily where you are located, you should be able to find one of the other options listed above.

Fabric

The higher end industry standard for this is Guilford and Maine acoustical fabrics. However, there are multiple potential fabrics to use for this application – but you can’t use just anything. It doesn’t need to be acoustically transparent, but it’s important to find a fabric that isn’t acoustically reflective. Absorptive fabrics (like felts) are okay.

The easiest (and generally least expensive) to use is burlap or jute, which both tend to have large enough holes between the threads to let the sound in, but not too large as to allow the fibers of the core material out. You can also use various cotton or polyester fabrics. Some say that if you can blow air through the fabric without too much resistance then you have a decent fabric for this application. You can use thicker fabrics, and they’re especially good for durability, but I’d just suggest not going for anything too thick unless it has thicker/textured threads (and thus appropriate spacing between them).

If you can take a good look at existing acoustical treatment somewhere, check the look and feel of the fabrics they use. If not, just use your better judgement. Be sure to get fabric that’s off a bolt at least 56″ wide (and preferably a little larger), so that you can wrap that around the 48″ length of your panel. Anything smaller and you’ll have to buy twice as much fabric!

(Commercial applications require panels that are up to fire code. Failing that, you may have problems with insurance. If you’re putting panels in a commercial location, do a little research on that before hand, and be sure you get appropriate fabric for that application.) Okay then, let’s get down to it!

Step 1: Prepare Your Materials

Use your miter or circular saw to cut the framing lumber to the right sizes (or have it cut where you purchased it). I’m going to assume you’re using the Roxul Safe’n'Sound, which is actually 47″ x 23″, so I’ll give cuts that suite that size. You’ll want the outside of the frame to be exactly 2′x4′. With the thickness of the frame at 3/4″, that’ll put the inside of the frame at 22.5″ x 46.5″. Don’t worry, the Roxul will squish quite nicely into the frame for a snug fit.

The edges of your frame will connect in a butt joint. Cut 16 pieces at exactly 24″, and another 16 pieces at 46.5″. When you account for the thickness of your saw blade, you won’t be able to get four short pieces out of your 8′ piece, so alternate. You’ll get two full panels worth out of every three 8′ pieces. Smell the pieces of lumber. Doesn’t freshly cut pine smell awesome!?!

Cut your fabric into 1 yard pieces. If you purchased exactly 8 yards, you may want to cut at 34″ instead of 1 yard to compensate for less than perfect cuts. 34″ will be more than enough. Your plywood should already be cut to 2′x4′ pieces before you leave your builder’s supplies outlet.

Recap

  1. Take your framing lumber and cut 16 pieces at exactly 24″, and another 16 pieces at 46.5″.
  2. Smell the freshly cut lumber (because it smells awesome).
  3. Cut your fabric at 34″ (assuming it’s from a 56″ or larger bolt of fabric). 8 pieces.
  4. Have your plywood cut at the builder’s supplies outlet into 2′x4′ pieces. 8 pieces.

Step 2: Build Your Frame

Line up the wood for your first frame. If you do not have a brad nailer, pre-drill a hole for 1 screw at each joint. Pre-drilling is crucial to keep everything aligned and prevent splitting. Apply the glue and screw the frame together. Keep in mind, the screw is only there to hold the frame together until the glue dries. The glue will form a much tighter bond than a screw could.

Apply a bead of glue all the way around the face of the frame and put a plywood backing on it. You may have to shimmy the frame a little if it’s a bit of a rhomboid. It probably won’t be perfectly rectangular until you adjust it. Now drive some nails through the ply into the frame. Don’t skimp on the nails.

Recap

  1. Line the pieces for the frame up in preparation for assembly.
  2. Pre-drill a hole for one screw at each corner (going through the 24″ piece into the end of the 46.5″ piece).
  3. Apply glue to the ends and screw each corner together.
  4. Put a bead of glue all the way around the part of the frame facing up.
  5. Put the plywood backing onto the frame and use it’s shape to straighten the shape of the frame.
  6. Nail the backing into place.

Step 3: Wrap The Frame In Fabric

Insert the core material into the frame. If you purchased spray adhesive, coat the center of the inside of the back panel with some adhesive first, and the edges of the core material if you desire. Put on some gloves before handling the core material. Roxul is a rockwool, which is essentially fiberglass. It’s not a health hazard, but it’s definitely an irritant. Wear long sleeves too, and wash you hands with cold water afterwards. Cold water keeps your pores closed while you remove any fibers that may be on your skin.

Once the Roxul is in the frame, set it aside and lay a piece of fabric down on your work surface. Place the frame face down onto the fabric, leaving even amounts of fabric on each side. The best way to wrap a panel is like how you wrap canvas for a painting. To ensure it’s tight and even, start from the center of each side and work your way to the corners, pulling tighter as you get closer to the corner. Staple the fabric down at the back. Don’t skimp on the staples. Every 3 inches or so should do the trick.

Recap

  1. Put on gloves before handling rockwool core material.
  2. Apply spray adhesive to the center of the inside of the back panel, and to the edges of the core material.
  3. Put core material into frame and set aside.
  4. Lay out a cut piece of fabric (34″ x 56″+).
  5. Place the frame with core material face down in the center of the fabric.
  6. Wrap the fabric around one of the long sides first. Start by stapling it into the plywood in the center of that side.
  7. Stretch the fabric from the stapled center toward one of the corners on that side (so that it is being stretched lengthwise on that side) and staple the stretched fabric every few inches. Do the same again from the center to the other corner on that side of the panel.
  8. Then do the opposite side, starting with the center, and this time making sure you pull the fabric tight across the width of the panel. As you stretch the fabric toward the corners, make sure you are stretching both length and width.
  9. Do the same process with the short sides, taking care to fold the corners neatly.

Step 4: Choose Placement

For placement, there are numerous techniques and every room and application is different. For the best and simplest rule of thumb in a home theater or control room environment, you’ll get great results placing them at first reflection points from your sound source. There’s an easy way to determine these spots.

  1. Sit in the seat you’ll normally listen from, facing as you usually would.
  2. Have a friend place a mirror flat against the wall and slide it around until you can see one of your speakers from your seat without shifting yourself to see try to see it.
  3. Mark that point with a piece of tape.
  4. Do the same for each speaker and each wall and the ceiling.
  5. Place your panels over as many or these spots as possible.

Step 5: Hang Your Panels

Mount your panels using the mounting hardware. Make sure you mount them safely. They’re not too heavy, but you certainly wouldn’t want one falling on you. If you are mounting to the ceiling, be sure to attach appropriate mounting hardware to the sturdier wood of the frame of the panel, instead of just into the plywood backing.

Instead of hanging the panels, another option for studio environments is to attach two panels together with hinges and use them as portable baffles for isolating amplifiers and drums.

Prepare You Materials

  1. Take your framing lumber and cut 16 pieces at exactly 24″, and another 16 pieces at 46.5″.
  2. Smell the freshly cut lumber (because it smells awesome).
  3. Cut your fabric at 34″ (assuming it’s from a 56″ or larger bolt of fabric). 8 pieces.

  5. Put the plywood backing onto the frame and use its shape to straighten the shape of the frame.
  6. Nail the backing into place.

Wrap The Frame In Fabric

  1. Put on gloves before handling rockwool core material.
  2. Apply spray adhesive to the center of the inside of the back panel, and to the edges of the core material.
  3. Put core material into frame and set aside.

  4. Do the same for each speaker and each wall and the ceiling.
  5. Place your panels over as many or these spots as possible.

Hang Your Panels

  1. Hang on the wall or ceiling, being sure to use appropriate hanging hardware for their weight.
  2. If hanging on the ceiling, attach the hanging hardware through the plywood backing and into the actual framing lumber, instead of just the ply backing, which will be less stable on its own.
  3. Instead of hanging the panels, another option for studio environments is to attach two panels together with hinges and use them as portable baffles for isolating amplifiers and drums.

Aaaaaaaaand you’re done!!

Now listen to the results! If you’ve never experienced something like this before, you’ll be surprised at the difference between the sound quality of your room before and after this acoustical treatment. Your favorite audio, whether music or movies, will now sound as it was intended to (i.e. frackin’ awesome!).

Week 13: DIY Guitar Repair

Last Sunday I decided to put some time into fixing up my old acoustic. It’s the guitar that came with me everywhere throughout high school and the years following. I literally never left the house without it, and it really took a beating over the years because of it.

Years back my family and a bunch of people at a place called the Kilt Pub that I was playing at a couple nights a week all put to buy me a new guitar – a beautiful Washburn. I’ve been playing it predominantly since, but I’ve always wanted to get my old guitar back in good working order. It’s got a lot of sentimental value, and I always loved the tone.

After recording Glenn Leybourne and his rich sounding guitar last week, I felt inspired to get on with fixing up mine.

Bridge Caving In

The pressure of the strings pulling on the bridge had been causing a larger than normal dip in the face of the body between the bridge and sound hole. This started many many years ago, and got to the point of causing the a lot of fret buzz. Well, back then I didn’t do a very good job of fixing it. In fact, my ghetto fixing job consisted of cramming a couple blocks of wood inside the guitar as a wedge between the face (sound board) and the back.

This worked for many years, but eventually led to a slew of other problems. First, it started causing the back of the guitar to extrude. Then, because the pressure from the strings was being redirected, it caused the seem between the sound board and the sides to crack.

My early 2000′s ghetto fixing job for that problem was to duct tape it up! I suppose I just thought it didn’t matter at that point. :D

Fixing It Properly

Well, I really should have just fixed it properly back then. It really didn’t take much time at all. So this time around, I put the time in.

Cleaning

My first course of action was to get rid of the old strings and start cleaning it up! Look at all this dirt!!

The fret board was easier to clean than I thought it would be, though still took a little time. The best way to clean it is a nice little trick – use steel wool! It has to be very fine steel wool (it should be 0000 fineness) to avoid damaging the wood. But it’s amazing how well the steel wool works!

I also wiped everything down with a sham-wow and some wood soap.

Of course, I had to leave the duct tape and stickers. They’re as much a part of the guitar these days as the strings are!

 Fixing Internal Bracing

After removing the strings and cleaning things up, I pulled out the old blocks I had within the guitar and inspected the internal bracing. As I suspected, there were problems

The bracing includes a main “X” shape. It turns out this was only connected to the sound board by two of the four points. To fix it, I used standard carpenter’s glue. I used a Popsicle stick and hold the bracing out from the sound board, and then used a thin piece of cardboard out of the recycling to spread the glue between the bracing and the sound board.

I couldn’t reach the further point with a clamp, so I used the internal blocks again to hold the bracing ’til the glue dried. I clamped the bracing closer to the sound hole.

Miscellaneous Fixes

I couldn’t afford new machine heads, so I just took them apart, cleaned ‘em up and tightened everything. They’ll suffice for now.

I also fixed a fret that had a dent in it since I was about 16 years old. I throw a large rock into a planter near the Coffee Time we all hung out by, forgetting that I had left my guitar in the planter for safe keeping. :|

Anyway, it took a while to pry it out, but I eventually got the fret loose with some pliers. I straightened it the pliers and gently hammered it back into place.

 Lowering The Bridge Nut

The next morning, after the glue had dried, I threw a new set of strings on it to check the action – which wasn’t very good at all. I had replaced the bridge nut years ago and raised it to compensate for the other problems. It seemed that wasn’t necessary anymore.

But before I filed anything down, I checked to see if I needed to adjust the truss rod. This can be quickly tested by pressing down the first and last fret and checking the space between the frets and the string around the area of the 12 fret. There should be a space, but it should be too small for even a credit card to fit.

It seemed my neck was perfect already, so I moved on to filing the bridge nut. I just used a little sand paper. I put the nut back in and strung it up again.

End Result

I’m so happy with the end result!! The bracing is holding strong – as good as new. The body feels strong again and doesn’t creak anymore! The action is decent. Not perfect, but far better than it’s been in years. The damaged fret works properly again, and the fret board is nearly as clean the day I bought it.

But best of all, it sounds just like I remember it sounding so many years ago! The tone and timbre brings back so many different memories and vibes from all those years of playing countless hours, all night, in myriad places, with so many great people. The reminiscing inspired me to play ’til my fingers were raw. :)

It feels great to have my old guitar back in such great condition. At first glance it still looks beat up because, well, in many ways it permanently is. I have no intention of ever fixing the cosmetic damages. They’re just marks of the years of service. They’re battle scars. Like the duct tape and stickers, they’ll remain until the guitar crumbles to dust and ceases to be.

But structurally, and tonally, she’s back in her prime! I can’t wait to use it on some recordings. I’ll be sure to share them with you when I do.

Week 12: DIY Studio Sound Absorption Panels

(Update: Click here for the full diy sound panel tutorial, or visit InityAcoustics.com for professionally made panels)

This week I took on a little DIY project for the studio. I’ve needed some sound absorption acoustical panels for a while now. They can be pretty pricey – anywhere between $60 and $200 per 2′ x 4′ panel – but the materials themselves aren’t nearly that expensive.

So, I made some myself… for under $20 a piece!

Sound absorption panels not only make a huge difference in a studio, but they’re also quite useful in any home theater or media room. We’re all generally used to acoustically untreated rooms, so we don’t even realize what a difference they can make. But when sound bounces off walls before reaching the listener (or microphone, in the case of the studio) it gets muddy. The short delay in the reflected sound causes a subtle echo effect that greatly reduces clarity and distinguishability.

Sound absorption acoustical panels effectively cut the reflections off hard surfaces in the room and leave you with just the clean, direct, unadulterated sound. This is why movie theaters have giant panels on every wall. In a home theater, It’s like combining the clarity of headphones with the power of surround sound speakers!

Glenn Leybourne

In the studio the panels serve to create crisp, clear recordings. I built the panels last night, and today we had a great acoustic player in the studio by the name of Glenn Leybourne. Anything short of the clarity of an environment treated with these panels would be an injustice to Glenn’s great sounding voice and guitar. Give a listen to this!

New York’s Not My Home – Glenn Leybourne

Crisp and clear!

The panels are pretty simple structurally – made from sound absorption insulation within a wooden frame and wrapped in a sound-transparent fabric (that lets the sound through to be absorbed by the insulation, instead of reflected by the fabric). In my next post I’ll do a little tutorial on how they’re made.

In the meantime, enjoy Glenn’s music, and stay creative!

Week 11: Bob Marley Cable Caddy

Featured

I saw this simple but joyful idea recently when a friend shared it with me on Facebook, and I just had to do up my own version for the studio!

Here’s the Bob Marley Cable Caddy. Simple, but ever so effective! I’m not sure who came up with it originally, but I hope you like my rendition of the idea.

Happy St. Patrick’s Day! Time to get back to my drink. :)

Week 10: InityPirates.com

This week’s creation came at the request of a regular Inity Studios artist named Chris Tipsy who wanted a place to share his 2011 release The Game Of Life Mixtape. I’ve long thought that it would be great to have our own private, customizable place where we could give away music created by myself and other Inity artists for those who would otherwise seek to download a pirated copy elsewhere. With Chris’ suggestion I thought why not include our local, connected musical family and make a broader community out of it?

InityPirates.com is a site based on “permissive piracy”. It’s permissive because, well, the artists said it’s okay. But it’s piracy ’cause free, full, high quality mp3s of entire albums that are for sale elsewhere is as good as robbery! Of course, you can always make a donation to the artist(s) if you choose to.

The site will have Inity Studios artist, as well as our friends, including artists recorded by Diverse and others. It is newly built, so will have more artists and albums added soon. I haven’t even got any of my own tunes up there yet! But there are a few artists with great music up there already.

Delay and Perfect, or Warts and All?

Although the site does just fine it’s main purpose of making mp3s available for playing or downloading, there’s still many problems with the site at the moment. For starters, the social sharing doesn’t seem to function as it should. Also, getting the PayPal donation button to work properly has proven equally difficult, so I had to leave it out for the time being. There’s some fundamental issues with the way the artist/album pages are generated that I haven’t been able to resolve yet.

But, as much as the perfectionist in me wants to fix all that before launching, Weekly Creations is all about getting something finished and posted. It’s Saturday night, at the end of week 10 of the year, and there’s no delaying tonight’s post. I’m proud of myself for keeping to schedule this far! The perfectionist in me cringes each weekend. But I’m glad to be posting. :)

So here it is, warts and all: InityPirates.com

 

Week 9: “Good Vibes” – Acoustic

Featured

While I haven’t gotten into some of the creations I hoped to make by now yet, I am kind of enjoying doing there little acoustic tracks. This one is a tune I wrote a few years back called Good Vibes.

I recorded it on my iPhone for convenience sake, so the sound quality is a little less than the others, but it’s still half decent anyway. I always liked this particular song. Let me know what ya think of it!

Coming Projects

I suppose an acoustic version of an old track isn’t as much of a “creation” as it is just a little performance. Admittedly, I only did today’s track as a last minute thing because any of the other creations I could have potentially posted just aren’t quite there yet. I have a few other creations on the go. One is another website that I started at the request of an artist that frequents Inity Studios. You’ll probably see that one next week.

I want to move away from so many web projects and little acoustic performances. At the start of the year I would never have assumed I’d be focusing so much on web stuff with Weekly Creations. I hope to get into a few tech/electronics projects in the coming weeks. I have some great projects in that department that I just need to drop a couple bucks into.

(On a side note: If you or anyone you know has any old electronics, drop me a line! Particularly any old computers or LCD monitors or TVs – preferably working, though items with malfunctions, dead pixels, etc. are still potential useful.)

Aside from the tech and web projects, I also have some quality final recordings and new songs that I’m working on – things of a little bit more substance that I’m looking forward to posting.

So until next week, stay creative!

Week 8: “Right Back” – Sublime Cover

Happy Birthday Bradley Nowell!!

Here’s another birthday cover for another incredible musician who died too young. If you know me, you know I’ve always loved Sublime’s music. Although I haven’t jammed on their tunes in a while, I used to play their stuff everyday. I love Sublime!!

Here’s one of my favorites. :)

Week 6 – #2: “Get Together” – New Demo Recording

Photo by Natalie Miller

A second post for week 6! I’m on top I’m my game this week. :)

I wrote this tune at the first sign of summer weather last year, but never took the time to record it. I had the idea in mind with just a simple acoustic thing I put down on my iPhone, but left any work on it for “later”.

Then, earlier this week my neighbor who runs the restaurant downstairs came by with a case of Coronas that a party had requested with their booked but only drank a couple out of. So, this is what happens when you combine a discount case of Coronas and a warm week in February with a guy like me. Looks like summer came early!

 

Normally I’d give a tune at least a couple days so I can come back to it with fresh ears to finish it off. But this is just a first run demo, and the Weekly Creations vibe is all about wrappin’ it and putting it out there. So, tell me what you think!

Week 6: “Johnny Was” – Bob Marley Cover

Happy Birthday Bob!!

It’s rare for someone to be called a “Legend” and society unanimously agrees. John Lennon, Bruce Lee and Bob Marley are three undisputed Legends. None can compare, but we can all pay tribute.

I always love jammin’ on Bob’s tunes. This is one that doesn’t get played much but is just an insanely awesome song. I hope you enjoy it!
