Sound Data
|
|
The values of the sound levels given in the tchnical charactgeristic chart are sound pressure olevels measured in dB(A) at a distance of 3m with the maximum airflow.
To obtain the sound power level at A or B, for extract operation, add to the sound pressure level (SPLExtract) given in the Technical Data chart, the correction value shown in the following table.
