Premises and sound recording
In addition to the useful signal, background noise is present in the recording. If this noise is the result of a breath of wind, then you can get rid of it with special protection for the microphone. If the sound is recorded in the studio and nearby, for example, there are unwanted sound sources, then soundproofing is necessary (although when choosing the location of the studio, you should always carefully study the noise picture of the surrounding space, if there are any serious noise sources that can interfere with further work).
¹Soundproofing is as much an art as choosing the best microphone/recording technique. Most often, soundproofing is done to absorb street noise. Sometimes a second wall is placed, sometimes the walls are simply treated with sound-absorbing materials. It often makes sense to replace doors and windows. What exactly needs to be done depends on each specific case and possibilities.
In addition to the problem of external noise, there is also the problem of the acoustics of the room itself, in which sound recording will be made.
Each room has its own acoustics - the characteristic reflections of a sound wave from the surfaces of the room. Be it reverb, echo, flutter echo.
Different rooms react differently to different sound sources. When choosing one here again, everything is relative. To record sounds, it is best to reduce sound reflections to nothing (anechoic chamber).
At the entrance to such premises, it is usually pawned in the ears. In general, the fight against sound reflections is done using two methods: 1) Increasing the area of ​​​​absorbing surfaces 2) Adding forms that crush sound waves.
In the first case, additional sound-absorbing material reduces the level of wave reflections from surfaces (by how much and at what frequencies depends on the material, see sound absorption table).
In the second case, various forms are added to the room, which separate the sound waves into smaller ones (the sound wave is partially reflected in different directions), which are much faster absorbed by the surrounding space.
