Why have small rooms an acoustic problem?


Nowadays, most recording studios or even home studios prefer doing it smaller rooms, as there is lesser reverberation in these kinds of rooms and for contemporary interior design. However all rules of room acoustics and soundproofing forget to take into account smaller rooms, and that is where all the issues arise.

Firstly, smaller rooms have walls that are closer to one another, and so the distance of a travelling frequency’s wavelength is often cut into half. This kind of reflection prevents the creation of clear and intelligible audio, and this creates an issue. Creating a home studio in the basement is also the worst idea even though contemporary interior design labels it hip, because not only does the distance but the kind of wall also matters.

For example, a standard sheet wall in a recording studio is not as sturdy as the cement walls in the basement of your house.

Additionally, people assume that small rooms do not have peaks (high-frequency points) and nulls (low-frequency points) especially at low frequencies and not just the mode frequencies determined by the dimensions of the room. For any given low frequency, at some part of the room, there will be a peak and a contrasting null to it.

The difference in base frequencies is easy to spot in smaller rooms because of an audio playing at 50Hz for example, it will sound low at some points and extremely high at others. There are a lot of deciding factors on what kind of room should be taken and how it should be kept. From the size and type of walls to the distance between them, to the kind of materials being used for acoustic treatment, the amount of furniture and equipment kept within the room to its placement – everything becomes really important.

Where the mike and speakers are kept is important in this scenario, but the interior design should be kept stylish and contemporary.

Lots of people think that they can jam better in smaller and untreated rooms, but that is incorrect because the music is either not fully intelligible or merely passes through the walls and you don’t fully hear it. Therefore after treating the rooms aptly, play a CD that is akin to the kind of music you plan to create and adjust the modes and frequencies accordingly for an optimum experience.
