Everyone that works with sound in some capacity knows how important the acoustics of the room they are working in is. The acoustics are the properties of an area that determine how sound is transmitted throughout the space. The following are three rules that anyone working with sound needs to follow in order to achieve the perfect acoustics for a room:

  1. Get rid of reflective surfaces – Not everyone has access to a professional studio in order to work with sound. You may have to work with what you have, which could mean that you’re stuck using a spare room or basement. Because every room is different, you’ll have to treat each room differently. The first thing you need to do is get rid of any reflective surfaces. Reflective surfaces, such as the glass in windows, will be detrimental to your stereo image and can cause you to hear your audio repeat itself several times as it bounces of the reflections. This means that you’ll need to cover any glass in the room. Cover up windows with curtains or blinds, and don’t forget to cover polished areas such as hardwood floors with carpeting as well.
  1. Position your listening position correctly – Don’t just prop your listening setup wherever it seems most convenient; where you position yourself is vital to achieving the perfect acoustics. Avoid tucking yourself into an alcove and try to keep as far away from any walls as possible. Rear ported speakers should be placed ten inches away from any hard surface in order to properly produce bass. This goes for sub woofers that are side or rear ported as well. If the space you are using is oblong, then position yourself in line with the longer part of the room to allow low frequencies to develop and to prevent reflections from the back wall.
  1. Adding absorption or diffusion – Absorption is one of the most used treatments for home studios. Whenever there is a lot of reflection in a space, absorption is needed to prevent an echo that affects your mid and high frequencies. You can get absorption tiles to place on your walls. Don’t use too many or you’ll end up with a dead unrealistic space. You want a little bit of reflection to create a realistic stereo image that is more natural. This also means that if you have absolutely no reflection in your room, you’ll want to add diffusion.

Although you may have access to a professional studio if you are taking DJ training classes or going to sound engineering school, knowing these basic rules for creating the right acoustics for your sound design can help you set up a studio in your own home.
