I’ve decided to pick up singing again, and am taking voice lessons now. Part of my homework is practicing at home to better learn breath control, etc. Sometimes that requires singing at a normal or louder volume, but I don’t really want to bother my next-door neighbor.
In music classrooms and recording studios, you often see acoustic foam tiles like this, the spiky mini-pyramids or ridges like this:
I know they’re available online, but I’ve never tried installing them on my own. Do I need to be concerned about their specific material (both in terms of sound dampening and potential fire risk, etc.), their size, or placement?
Like do I need to position them in any particular sort of pattern to best attenuate the sound of a human voice (in terms of wavelength, etc.), or is it more or less just “grab a bunch and stick them wherever”?
Bonus question: Are there any that are somewhat prettier, like maybe acoustic foam with landscapes or art printed on them?
I came here to say just that. Those cones just make your voice “dry” so basically do take out Echo and Reverb but won’t lower what your neighbor is going to hear.
Going back to the acoustic panels, you would need to cover the entire wall in your neighbour’s direction, every square centimetre without exception, to make any difference. Any through-path whatsoever will make the rest pointless.
And depending on the setup of your place vs theirs, you may need to do at least part of the side walls, ceiling and floor too.
