One of the most critical, yet overlooked areas of audio is speaker placement. Speaker placement will not only determine whether or not you can hear the audio, but it will also effect the tonal and intelligibility of the sound. In the next few articles we will look at some of the factors that go into proper speaker placement.
Speakers produce sound in a cone starting at the speaker and radiating outward at a wide angle. You can even measure the width of that cone by replicating this simple demonstration. Set up a speaker in a large empty room. As the speaker is playing, walk accross the front of the speaker perpendicular to the direct the speaker is facing. You will notice a point where the sound becomes clear and louder, and a point where the sound seems to muffle and decrease in volume. If you were to mark those points, and measure that angle, you can find out the “dispersion angle” of the speaker.
