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 absorber’s inner space with sound-absorbing material based on mineral water reduces the device’s working frequency.

Moreover, it also reduces absorber’s Q-value, which enhances its working diapason.
