- Abstract
- The first part of the paper deals with the determination of the minimum amount of sound absorption necessary in a room so as not to produce a space interference node at a certain distance from the loud speaker when that is emitting a steady tone. Two cases are investigated—the amount of sound absorption necessary in the room that will make it impossible to find a node within a given distance from the emitter; and the amount of sound absorption in the room that will make it improbable to find such a node within the same given distance from the emitter. The second part of the paper deals with the minimum amount of sound absorption necessary in a room so as not to produce time interference nodes during the decay of a tone in the room. Here again two cases are considered-the amount of sound absorption necessary to make it impossible to produce nodes during decay; and the amount of sound absorption as mill make it improbable lo produce such a node in the room.
