Equipment Sound Rating
A reverberant field is nearly the opposite of a free field. Reverberant fields
exist in rooms with reflective walls, floors, and ceilings. When a sound source is
placed in an enclosed room, the sound waves from the source bounce back and
forth between the reflective walls many times. This can create a uniform, or
diffuse, sound field. In a perfectly reverberant room, the sound-pressure level is
equal at all points within the room.
Special reverberant rooms are designed, built, and qualified for the purpose of
measuring the sound emitted by a piece of equipment. This type of facility will
be discussed later in this period.
