Measurement Principle of Equivalent Absorption Area of Rooms by Using Reference Sound Sources

초록/요약

KS F 2810-1:2001 adopts the concept of normal and standardized sound pressure level for the impact sound insulation performance. In these measurement, the equivalent sound absorption areas are ordinarily obtained by measuring reverberation time in the receiving rooms. However, measuring the reverberation time needs additional instrument and different procedures from sound pressure level measurement. Therefore it is very useful and desirable if the sound absorption area can be obtained only by measuring sound pressure level instead of measuring reverberation time. In this study, the principle of measurement method of equivalent absorption area by using reference sound sources and the measuring process are reviewed.
