HOFA Basstraps reliably absorb low frequencies for balanced room sound in studios, recording rooms, home cinemas & hi-fi rooms.

Acoustical Effectiveness of HOFA Basstraps

The measurements were conducted on 21.11.2011 in a reverberation room wich has been designed to fulfil DIN EN ISO 354:2003.

What does this measurement show?

From 80 Hz to below 200 Hz the basstraps absorb over 90% of sound energy*. Well below 80 Hz sound energy is still noticeably absorbed.
It can also be seen clearly that the absorption above 1KHz is less intense to obtain a natural ambient sound.

Approximately calculated in reference to the curved surface area of the HOFA Basstraps wich is about 1,35 m2.

With a typical placement in the room corners, the HOFA Basstrap achieves a weighted sound absorption coefficient of αw=0.80 (L). The determination was carried out according to DIN EN ISO 11654.
