Acoustics The transmission and reflection of sound waves has now been reduced to a matter of ex- act scientific knowledge, and we are able accu- rately to solve the problem of acoustics as gov- erned by known conditions. In other words, we now know under just what circumstances a sound wave may be projected a maximum dis- tance; under what conditions it will be muffled, deadened or destroyed, and this knowledge en- ables us to secure good acoustic properties in the erection of a theatre. A sound wave starts at the origin of the sound and expands in all directions until either lost by constantly diminished power, or reflect- ed, as a ray of light would be, into other direc- tions until diminished to inaudibility.
