ISO 3382-2:2008规定了普通房间中混响时间的测量方法。它描述了测量程序、所需的仪器、所需的测量位置数量，以及评估数据和提交测试报告的方法。 测量结果可用于校正其他声学测量值，例如声源的声压级或隔声测量值，并与室内混响时间的要求进行比较。

ISO 3382-2:2008 specifies methods for the measurement of reverberation time in ordinary rooms. It describes the measurement procedure, the apparatus needed, the required number of measurement positions, and the method for evaluating the data and presenting the test report. The measurement results can be used for correction of other acoustic measurements, e.g. sound pressure level from sound sources or measurements of sound insulation, and for comparison with requirements for reverberation time in rooms.
