Are you aware that the selection of building materials aids in the acoustics of a building? Controlling sound in many commercial buildings has become an awareness in the construction industry. The control of long and short wave lengths is dependent on the absorption and reflextion of the acoustics in a building. The rambling and friction of air molecules in a small area determines the diffraction of sounds within the walls. Construction and selection of foam materials, fibre glass panels and curtains helps in antinode and node of sounds in these buildings.

Long waves in small rooms.
There may be apps that do that. You can definitely find spectrum analyzers that will measure ultra low.
Is there an APP that can measure the ultra low frequency levels?
.Plaster is a viable middle and high frequency absorber. We have used it many times in new builds that have…
Hi Dennis I'm curious what you think of acoustic perforated plaster - say CST Galaxy -on particularly ceilings in music…
