Thank you for posting about the bass trap, I had never heard of it before and am enjoying spending time learning about it (and the other sound-dampening materials you mentioned)
This makes me wish I could put some bass traps in the wall between one neighbour and me, and something like hemp crete to drown out the sound of the screaming kids from another neighbour!
- georgn 8y agoBy all means, read up on bass traps... but be aware that posts about bass traps imply a fundamental misunderstanding of what they do (perhaps I'm misreading). The problem: a speaker in a room produces sound, that sound is reflects by the walls. Those reflections will vary WRT phase of the original sound and causing something called comb-filtering (some frequencies will be louder because the reflections are in phase and amplify -- others will be 180º out of phase, resulting in a complete cancellation of those frequencies). Solutions: sound attenuating material at the edges of a room to interfere with the _reflections_ and this reduce or eliminate comb-filtering. The goal is to improve the listening experience _inside_ the room. Acoustic treatment does almost nothing to help your neighbours.
