![]() ![]() These frequencies are handled with units called Bass Traps. Low frequencies, bass frequencies, can be a particular problem. Some frequencies are more of a problem than others. This reduces the effect of the bouncing waves by making sure they cannot bounce back and forth like your reflection between two parallel mirrors. If you think of a well-built cinema, none of the walls are parallel. If you think about this, this more or less describes any room in any normal house. If you have two walls parallel to each other, any sound can bounce between the two compounding the problem. The second thing you can do is change the direction of the reflections. Note that none of these materials will soundproof your space. The quickest way to do this is to soften the hard surfaces by adding blankets, cushions, acoustic foam and so on. There are two things you can do to go in the other direction to reduce reflections.įirstly, and most obviously, you can do something to reduce the quantity of reflections, even change their nature. ![]() You have just built yourself an echo chamber, and that is the last thing you need for recording an audiobook! Acoustic design and treatment is all about what happens to those waves next.įor instance, if your walls are tiled with nice shiny ceramic tiles and the walls are parallel to each other, the sound waves will bounce back and forth for ages. Those sound waves will eventually hit something like a wall. When you make a noise in a room, like talking, that sound is transmitted through the air in sound waves in a very similar way that waves travel through a bowl of water when you drop something in it. What you are aiming for is a noise floor of at least -60db - that is pretty quiet, all told, and if you are doing a lot of this, and can get it lower, better still.Īcoustic treatment is a different beast. Material and techniques that reduce the transmission of vibrations.Dense materials like concrete, bricks, or thick dense rubber to absorb sound waves,.Soundproofing prevents sound breaking through and is achieved in two ways: ![]() There are a huge number of options available here, both as self-build and bought in solutions, but all are trying to achieve the same thing a space that has good acoustics and that is isolated from outside sounds, whether that is a low-flying cow, next door's kid on her scooter or the annoying hum of your computer.įirstly, there is a big difference between acoustic treatment and soundproofing. The only part of this that can be free is the software, everything else will cost you cash! A Voice Booth
