ACOUSTIC TREATMENT: A SHORT GUIDE
The noise in the audio is something that every newbie in the field of recording faces. He doesn’t know what went wrong with the recording and wastes a lot of time redoing everything and trying to figure out what the problem is. This article will acquaint you with the problem and will suggest you the countermeasures.
The dynamics of sound:
Before eliminating any kind of sound, you must first know how the sound works. As soon as the sound comes out of your mouth or any other instrument, It has the tendency to travel in all directions. A small part of this sound will directly enter the microphone while most of it hit the walls around you and reflect back. This reflected sound will soon reach the microphone after reflecting numerous times and will create a noise that you hear in the background of your recording.
Why is the sound reflecting?
This is probably because of the shape of your recording studio. The walls absorb some sound while reflecting back the remaining. This reflected sound travels and hits another wall and this process continues until the sound loses its energy or is absorbed by any device.
How can you remove or minimize these reflections?
You can treat your room acoustically. You might have noticed some woody and foamy things fixed on the walls of a professional recording studio. These are acoustic absorbers and diffusers. They absorb a large amount of sound released by the instrument in their direction, taking up all of their energy. But even if the room is completely silent, the recording won’t sound natural. You have diffusers for the rescue. These diffusers diffuse and scatter the trapped sound from the corners but keeping the energy so little that it won’t create any noise in your recording.
Elements of Treating your room acoustically
Every sound falls under three ranges of frequencies. The low-frequency sounds, called the Bass, the mid and high-frequency sounds which are usually the vocals and the other music. Your first job will be to reduce the low-frequency bass. This sound has larger wavelengths and hence does not diminish easily. They keep reflecting and create a lot of noise. To deal with bass, you can treat the room with bass traps. These traps are usually fixed on the corners and absorb a majority of the low-frequency noises. The bass traps also have the tendency to absorb mid and high ranged frequency sounds but if you need an even more sophisticated absorption, you can always use the acoustic panels and diffusers. These devices, when fixed perfectly will give you the best recording of your sound.
SOUNDPROOFING OR ACOUSTIC TREATMENT
This is a common mistake done by all the recorders out there. They don’t know how one is different from the other and end up taking the wrong decision. Never get confused between these two. They have completely different jobs. Soundproofing is basically treating the room in such a way that no sound from the outside comes in and vice versa. Whereas Acoustic treatment is done to minimize the reflections of the sounds by the walls. You can definitely include soundproofing in your acoustic treatment plan but remember, they both are completely different and one won’t do the job of the other.
