RSc Active Bass Traps

EXPERIENCE RICHNESS OF DETAIL AND INTENSION OF THE ORIGINAL SOUNDSIGNAL IN THE LOW END LIKE NEVER BEFORE

Technically outstanding products and solutions that optimize the low-frequency sound of the room and utilize the sound potential of the setup.

Because: in the bass range you primarily hear the acoustic properties of the room, no matter what hardware you operate.

Experience a low-frequency sound with a richness of detail, that cannot otherwise be achieved in closed rooms.

Problem Definition

When optimizing room acoustics, special attention must be paid to the low-frequency range. Frequencies in the range from 20 to 200 Hz are subject to their own laws and are difficult to control with passive absorbers.

Room dimensions of listening or recording rooms are usually smaller than the low-frequency wavelengths are long (up to 17m edge length for 20Hz). This leads to standing waves in practically all rooms (also known as room modes), which are loud at some listening positions and barely perceptible at others. In general, room modes distort the frequency response, negatively influence the impulse fidelity and interfere with the positioning stability.

Our Machine Learning Bass Traps und Solutions

Depending on the circumstances and the desired result, we will advise you whether a Machine Learning Bass Trap or a custom solution is the right choice for you.

Our Bass Traps are equipped with algorithms that automatically generate digital room acoustics. We have developed them for noise cancelling applications in aviation. Included in the price is a short planning by one of our engineers to get the most out of your bass trap.

The basis of a custom solution is the analysis of the problem. In the second step we advise you, depending on your objectives, on different approaches. Our library of algorithms, the possibility to adapt them and the architecture of our systems allow us to adapt our system to any needs and acoustic phenomena.

In both cases, you choose between the three models according to the performance of your system.

Direct Comparison

Goal: Maximum shortening of the Modal Decay Times

With the RSc Bass Trap turned off, room modes are formed at 15, 30 and 45 Hz. In the waterfall diagram you can see their long decay times.

With the RSc Active Bass Trap switched on, a considerable shortening of the modal decay times is achieved in the targeted frequency range between 10-50Hz.

No post-processing of data or EQs was performed on the main system.

Goal: Maximum linearization of the low-frequency impulse response

In the untreated room (left) peaks and dips form in the frequency response due to room modes. This leads to a distortion of the sound event (+/- 20dB), since some frequencies are loud and sound imprecise, while other frequencies are barely perceptible.

With the RSc Active Bass Trap switched on (right), the sound is completely linearized in the targeted frequency range between 10-50Hz. The achieved impulse fidelity is unique.

No post-processing of data or EQs was performed on the main system.
