摘要:
本文论述了住宅隔绝空气声的计算结果与现场测量结果之间的差异的一些可能原因:诸如测量的频率范围、测点的位置、归一化声压级差的计算、混响衰减曲线的取值以及发声室与受声室的地位等。文中并提出了若干建议供讨论。
Abstract:
This paper discusses some causes of variation of results in field measurements and calculations of airborne sound isolation of dwellings, which includes the frequency range of the measurements, the position of the measuring points, calculation of SPL difference for normalization, evaluation of decay curves of reverberation, location and structure of the source room and the receiving room. Some suggestions have also been put forward.
