The Studio SOS Guide To Monitoring & Acoustic Treatment. The Studio SOS visits have shown that many home studio owners are having problems with their monitoring.
So this month we explain the principles anyone can use to get their own control room sounding right. Paul White. Do-it-Yourself Bass Traps By Ethan Winer. By Guest Contributor Categories: Audio Equipment There are several ways to create a bass trap from raw materials.
The simplest and least expensive is to place thick, rigid fiberglass panels straddling the room corners or flat on the walls spaced away with an air gap. Rigid fiberglass four inches thick and spaced well away from a wall is very effective to frequencies below 125 Hz. But many rooms have problems far below 125 Hz, and losing a foot or more all around the room is unacceptable to most studio owners and audiophiles.
Since bass builds up most in the corners of a room, this is an ideal location for any bass trap. Figure 19.4 shows the corner viewed from above, looking down toward the floor. One nice feature of the bass trap in Figure 19.4 is that the air gap behind the fiberglass varies continuously, so at least some amount of fiberglass is spaced appropriately to cover a wide range of frequencies. Another popular type of bass trap is the tube trap, invented and sold by ASC. The Studio SOS Guide To Monitoring & Acoustic Treatment. Why Your Bass Traps Don’t Work.
I’ve been behind on Pensado’s Place and I did some catching up the other night.
They had a super dooper acoustics dude on. His name is Thomas Jouanjean and he works at Northward Acoustics Engineering, the firm that built Focal’s facility for testing their monitors, among many other ultra high end studios. If you can’t see this video head over to Youtube and watch it. While I’m not exactly sure why, anytime they start REALLY hitting on super information that gets me excited, Dave Pensado tends to get goofy talking about the NBA.
I’m all for goofy both before and afterward, but I guess I REALLY wanted to hear what this French dude had to say. Acoustics Articles.

How To Build A Corner Bass Trap // Nagasaki Sound. I’ve finally pulled the trigger and fired up the new “Bunker Blog”, and thought I’d start things off with a fairly easy do-it-yourself guide to building a corner bass trap for your studio.
Most people have an idea, but just don’t realize how incredibly important it is to have a properly treated acoustic environment to work in. The off-the-shelf solutions offered via your typical gear retailer are vastly overpriced, one-size-fits-all, and are somewhat underwhelming in performance and looks. A couple notable exceptions are RealTraps and GIK Acoustics, but as Nagasaki Sound provides premium mastering at an affordable price, we like to save overhead wherever possible and pass that on to our clients via great rates. For less than the price of one large retail bass trap, I built 4 large corner bass traps and a fireplace bass trap, with leftover absorption material and hardware to spare. So let’s get to it, kid! Some of the tools used to build the corner bass traps. $29 bass traps...quick and easy...yet another DIY bass trap project!
Are we tired of these threads yet?
The truth is, that bass traps make a tremendous difference in a room. I had 10-15db nodes at 80 and 125 and huge decay times. 100% better now. Looking at the other project threads (all very creative btw!) , I had no interest in the frame building aspect of the project...oh ya...did I mention I'm cheap also? Anyway, here is my take on it. I used black felt from Joann Fabrics since it comes in a 72" width (which is necessary with this design) and it's only $4.99/yard. Be sure to use the rigid rockwool panels for this (not the fluffy stuff) Owens Corning 703, Roxul Mineral Wool, and Other Acoustic Materials I will post some room application photos in the next post.

J'ai emménage il y a un an dans un appart' près de Rennes, et comme tout appart', l'acoustique sent le vieux string, donc du coup, j'ai un son de merde dedans, et en plus un pic de résonance très très désagréable à 139Hz. J'ai entrepris de fabriquer des BassTrap maison pour tenter de remedier a ce probleme. Je vous raconte: J'ai donc parcouru plusieurs magasin de construction, bricolage et compagnie, aucun ne connaissaient la densité des plaques qu'ils vendaient, et encore moins les coeff d'absorption de sabine généraux, et encore encore moins par bande de fréquence...
