ISO 3382-1:2009规定了性能空间中混响时间和其他室内声学参数的测量方法。它描述了测量程序、所需仪器、所需覆盖范围，以及评估数据和提交测试报告的方法。它旨在应用现代数字测量技术，并评估由脉冲响应得出的室内声学参数。

ISO 3382-1:2009 specifies methods for the measurement of reverberation time and other room acoustical parameters in performance spaces. It describes the measurement procedure, the apparatus needed, the coverage required, and the method of evaluating the data and presenting the test report. It is intended for the application of modern digital measuring techniques and for the evaluation of room acoustical parameters derived from impulse responses.
