$X_{min}$: 200 $Hz$ $X_{max}$: 20,000 $Hz$ $Y_{max}$: Max SPL $Y_{min}$: Max SPL - 25 $dB$ $Z_{min}$: 0 $Z_{max}$: 4.5 $ms$

windows: IR response

• [/] CSD (Cumulative Spectral Decay) mode Rise: 0.580 $ms$ unsmoothed

Wave should be disappeared before 2 $ms$

Why measure only frequency greater than 200 Hz? The frequency below 200 Hz will be effected by Room Mode.
