半无响室#无响室的详细说明书@技术发布，无响室，无音室，半无响室，隔音室，静音室， 隔音房，静音房，工业隔音房，工业隔音室，工业静音室，工业静音房流水线隔音房，生产线隔音室，产品测试隔音室，产品测试静音房，工业隔音箱

     依据***ISO 3745“Acoustics-Determination of sound power levels of noise sources－－-Precision methods for anechoic ａnd semi-anechoic rooms”和***GB6882-86 “声学－－-噪声源声功率的测定：消声室和半消声室***法”中规定的消声室自由场鉴定方法进行测试。即在125Hz以下和4KHz以上采用1/3倍频程中心频率间隔单频信号，在125Hz~4KHz之间采用1/1倍频程中心频率间隔单频信号，测出实测声压和理论声压之间的差值，据此，根据ISO3745和GB6882-86规定的允许差值，可确定出允许的测量半径和满足标准的自由声场空区域。ISO3745、GB6882中规定的测量声和理论声之间的允许差值。
