Do-it-Yourself Bass Traps By Ethan Winer

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.

How To Build A Corner Bass Trap // Nagasaki Sound

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.

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.

[DIY] Panneau acoustique/ Bass trap

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...
