混响时间软件BZ-7227使您的2250-S和2270-S型能够以1/1倍频程或1/3倍频程测量混响时间。
混响时间应用程序 - BZ-7227
混响时间测量软件BZ-7227可以测量1/1倍频程的混响时间
该应用程序支持两种混响时间测量方法:脉冲激励(施罗德方法)和断续噪声。在脉冲激励方法中,当使用气球爆破或发令枪激发时,2250-S型自动测量混响时间。在断续噪声法中,声级计智能控制扬声器激励。
可以按顺序在多个位置进行测量。T20、T30和EDT参数都是针对宽带和每个倍频程频带测量的,以自动计算房间平均值。测量符合ISO 140、ISO 3382和ISO 354等标准的相关部分。
只需按下开始/停止按钮,引爆气球或发射发令枪;这就是在大厅、公共场所等进行混响时间测量所需的全部工作。
当您返回仪器时,最后一个位置的混响时间谱和房间平均值将已经显示在显示屏上。直观的“笑脸”指示器会立即显示您的测量结果是否良好或需要重复。
Simply press the Start/Pause button and burst a balloon or fire a starter pistol; that’s all it takes to take a reverberation time measurement in halls, public spaces, etc.
When you return to the instrument, the resulting reverberation time spectrum for the last position and the room averages will already be on the display. Intuitive “smiley face” indicators immediately show if your measurement was good or needs to be repeated.
