I am a guitar player and have played in various bands steadily now for over twenty years. From garages, sheds, basements, studios, and even dedicated music rooms, I’ve rehearsed in all the usual places that bands tend to use for their practice spaces. I’ve always gravitated towards bands that play more of the harder varieties of rock n’ roll, so of course that means big drums, big amps, and loud P.A. systems. It wasn’t until my early twenties, when I got into running live sound and recording, that I started learning about acoustics and how the make-up of a room can drastically effect what the musicians perceive while playing. This is why properly soundproofing a band rehearsal space is so important.

Sound Problem: Loud Room with Muddy, Unintelligible, & Fatiguing Sound Quality

four-piece-band-silhouette-rocking-out2Here’s a typical band rehearsal space scenario – You’re the guitar player, and you’ve spent all week learning the latest batch of tunes the band had decided to work on the week before. You get to rehearsal and are ready to rock. You are rehearsing in your drummer’s garage. It’s made up of a combination of sheet-rock walls, a concrete floor with a couple of area rugs, and a sheet-rock ceiling; a typical garage setup with all hard surfaces. The first song starts with just you playing, but once the rest of the band kicks in, you find yourself lost in the mix. That awesome solo you worked so hard on in the previous days gets drowned out underneath the mud and confusion of what your other band mates are playing. Since you can’t hear yourself, your natural reaction is to turn up your amp. This works great for a song or two, but then the bassist turns up his or her amp and the drummer starts hitting their drums a lot harder to compensate for the increase in volume that your amps are producing. The vocals get drowned out and soon you are back to where you were at the start. A similar scenario used to happen to me. A lot. Not only that, but this type of situation can also cause hearing fatigue and hearing loss if you’re not careful (ALWAYS wear hearing protection no matter what). There were a couple of bands I played in where I hated going to rehearsals for this very reason. What’s the point in rehearsing if you can barely hear yourself or what the other band members are playing so that you can work on making the songs sound better in the first place?

Sound Solution: Add Absorptive Materials to Room

Above & Below: Absorptive Panels Help to Dampen Sound and Reduce ReflectionsThe most effective treatment for this situation is to add soft, absorptive materials to all of the hard, reflective surfaces in the room. The band that I am currently playing in recently moved from rehearsing in the other guitarist’s detached garage to a room in our drummer’s split level house. This man-cave, located on the lower level of his home, has a combination of wood paneling and sheet-rock on the walls, pile carpet on the floor, and a textured plaster ceiling. There is also a large brick fireplace that takes up a good portion of one of the walls. The first time we rehearsed in the new space, the sound quality was horrendous. Harsh highs, muddy lows, and vocals that were fighting to get over top of the blaring guitar amps that were in turn trying to compete with the volume of the drums.

Above & Below: Absorptive Panels Help to Dampen Sound and Reduce ReflectionsIn a space such as this, I knew we would need as much absorption as possible. For this type of application, the more sound deadening material you can add to the room, the better. To fix the sound issues, we installed several 2″ thick Anchorage Fabric-Wrapped Panels (which are very similar to the more cost-effective AlphaSorb® Fabric-Wrapped Panels) to cover the wood paneling on the lower portion of the walls. We then added Sonex Acoustical Foam to the upper portion of the walls and above the drum set, all in an effort to kill as much of the reflected sound as we could.  The difference from before we applied treatment was night and day.  We were actually able to turn our amps down a little, as the volume of the drums was not as overbearing as before. The vocals through our P.A. system could now cut through the instrument mix better and were actually intelligible.  Instead of a wash of sound, the instruments were more articulate and you could pick out details that were lost otherwise without the treatment in the room. Our drummer’s wife even remarked that one of the cover songs she overheard us rehearsing sounded like it was being played off of a stereo. Quite an improvement indeed. Now every room is different, so there are other materials you can use to help with dampening sound in a band rehearsal space, as well.  In addition to what I have previously outlined, absorptive acoustical blankets can be hung on walls and garage doors, drum shields can be used to reduce the output of acoustic drums (while allowing the drummer to hear themselves better) and absorptive panels and gobos can be used to isolate and tame loud amplifiers.

Sound Problem: Sound Emanating from Band Rehearsal Space is Annoying Spouse, Kids, Neighbors, Etc.

Unless your band practices in a location that is out in the middle of nowhere, chances are there is someone nearby that might get annoyed by all your rock n’ roll exploits from time to time.

Sound Solution: Soundproof Walls and Ceilings with Materials That Block Airborne & Structure-borne Sound

block soundThis application has pretty much been covered in other blog posts, so I will keep this brief. In order to block airborne sound through walls, ceilings, and floors, you need to add heavy, dense materials to them. This can include using materials such as mass-loaded vinyl sound barrier, combination sound absorbing/blocking acoustical blankets, and Green Glue sound dampening compound.  For low frequencies such as bass guitar, kick drum, etc., those frequencies can actually vibrate the structure causing what is known as structure-borne noise. Treatment for this type of application calls for using products that isolate and decouple the walls, floor, ceiling from the studs and joists that they are attached to. This can include using materials such as sound isolation clips, floor underlayments, and vibration isolation pads.
