Bass Traps B500/B600

mbakustik’s new idea in modular bass absorption:
one box – two acoustic concepts

There are two concepts for low frequency bass absorption: resonance absorbers tuned to an individual room resonance and broadband bass traps which treat the whole low frequency area. Precisely tuned resonators are the most powerful bass traps available when combating narrow peak eigenmodes. But if their resonance frequencies don’t coincide almost perfectly with the room modes they are useless or even harmful. Therefore, an accurate acoustic measurement (modal analysis) on location is required. On the other hand, broadband bass traps are slightly less efficient but they work on any resonance within their frequency range, often even in the high/mid range.

As there are good reasons for both concepts we decided to offer the bass traps B500 and B600 in both versions: version A is tuned to a precise resonance frequency between 20 Hz and 60 Hz and offers maximal small band effectivity while version B is a broadband absorber and allows absorption without accurate knowledge of the dominant room resonances needed.

In addition to their main modes many studio rooms suffer from further resonances that also need to be treated. In these cases we often combine both versions of bass absorbers: While the dominant own modes are damped with tuned bass traps (version A), additional broadband modules (type B) act throughout the whole frequency range. In addition, the broadband version enables the creation of a reflection free zone around the listening position.

The B500/B600 bass traps are particularly effective in the time domain: they are reducing the low frequency decay of a room. As this behaviour is very difficult (maybe even impossible) to be improved by using electronic filters, the correction of the room acoustics itself is especially important here. Moreover, the frequency response at the listening position is linearized and the dependency on position of the sound field is reduced.

Simulation of sound absorption

The bass response of a room can not be described precisely using the model of the diffuse sound field, therefore sound absorption coefficients greater than 1,00 are reachable. Please notice the complementary behavior of B550B and B650B bass traps and A115 broadband absorber in the LF range.
