HOFA-Akustik Modules Field Test

All recordings for this Samples were held in the same room – only the frames were equipped differently for each recording.

So if you want to hear the voice sound (“Sprache”) in conjunction with absorbers in the frames, simply click on the lowest button in the first column.
Just compare this with the voice sound (first column) without modules (first button/”ohne Modul”) – it quickly becomes clear how effective our acoustic modules are. The tambourine (last column) makes it particularly clear, what kind of tonal possibilities the frames provide.

The two images below right show the particular instrument used and the type of acoustic modules applied.

Acoustic modules


We made our tests in a 18m² [21.53 yd²] room sparsely furnished with a table and a couch. The room was equipped with 4 HOFA Frames on each wall and 8 Frames on the ceiling. During the recordings we changed the room acoustics through the use of HOFA Absorbers and Diffusors. The microphone (AKG C 414 / spherical characteristic), the distance between microphone and instrument remained constant.


All in all decisively is, of course, personal taste. And every room sound has unequivocal strengths and weaknesses.

For the “professional” speaker/voice-over artist there can’t be enough absorption, nevertheless a tambourine develops its potential sound at best with diffusors and/or bare walls. With low frequency sounds, the mixture of different acoustic modules shows its superiority. The acoustic guitar behaves similar whereas the naturalness of the sound increases with the number of the diffusors.

The test shows which acoustical possibilities you have in a comparatively small room. In most cases, with home-recordings, you have just one room available for recording and mixing. When using the HOFA Absorbers, Diffusors and Frames you can attune the room to the respective situation.
Furthermore the versatility of the HOFA acoustic modules still allows having a creative leeway for experimenting with sound.
