Panel sound-absorber
Insert the meanings of construction sizes according to the drawing
After the insertion, press Calculate
Density of surface of panel kg/sq.m
Construction depth: sm
Resonant frequency: F 0 Hz
Theoretical working diapason:F low Hz
 F high Hz
Recommended minimal panel size:  m
Resonant frequency is mostly affected by 2 factors:
- Panel mass or density
- Size of the construction inner volume, which is defined by the size of the frame, where the panel has been put. Filling the absorbers inner space with sound-absorbing material based on mineral water reduces the devices working frequency.

Moreover, it also reduces absorbers Q-value, which enhances its working diapason.
