Front Wall Acoustic Treatment

Treating the entire front wall won t solve this problem at low frequencies nor is it needed or even useful at mid and high.

Front wall acoustic treatment. Broadband bass trapping systems covering the rear wall and front corners use hanging hidley panels. In general you should avoid having your speakers anywhere from 12 to 30 from the front wall unless you treat directly behind the speakers. When we re talking about professional quality acoustic wall treatment the active ingredient for lack of a better term is high density insulation commonly known as rigid fiberglass. If we re talking about consumer level egg crate material then the main and only component is high density foam.

You might however get reflections in the low mid and low frequencies as they are more omnidirectional frequencies. Front corner bass traps are surfaced with reflective material. For the front wall behind your speakers you probably won t get a lot of reflections in the high and mid frequency spectrum as the speakers monitors will be facing away from the wall. In fact in most small rooms having the speakers right up against the wall is the absolute best position.

Otherwise you can get cancellations and peaks in response due to reflections from the front wall. Once you ve done the best you can with the speaker positioning it s time to think about adding some bass trapping. Add in the multitude of room shapes sizes wall construction methods and surfaces found in home studios and it becomes impossible to provide a one size fits all guide to acoustic treatment. 12 pack set acoustic absorption panel 12 x 12 x 0 4 inches grey acoustic soundproofing insulation panel tiles acoustic treatment used in home offices by fstop labs 20 99 20.

Most thin absorbers made of acoustic foam or rigid fiberglass are ineffective below about 500 hz yet this is precisely where absorption is needed most if the goal is to reduce or avoid reflections off the front wall.
