Acoustic peace … A noisy group? Demanding neighbors? What was supposed to be comfort can quickly become unbearable… Sonum has only one shift, acoustically isolate your group!
Average observed attenuation of “5dB”
Our solutions have been tested in a semi-anechic chamber under conditions close to reality and according to the standards in force.
The average sound reduction observed on Sonum is 5dB
The average sound reduction observed on Sonum+ is 10dB (microphone positioned behind the sound barrier)
The average sound reduction observed on Sonum Integral is 17dB (microphone positioned behind the sound barriers)

Despite the efforts made by manufacturers’ “research and development” units, air conditioners still generate noise pollution which creates neighborhood disputes, night nuisance and other disputes, which very often end up, at best, in front of a mediator and, in the worst case, before a judge.
After many years spent studying the multiplicity of these situations, after several dozen prototypes, hundreds of customer feedback, acoustic surveys in real situations, we have created Sonum, the custom-made acoustic air conditioning cover.
Our French supplier of sound insulation offers you the best in sound insulation technology.
Quality, design and AMAZING results!
Sound reduction on a heat pump is a challenge.
A precarious balance must be maintained between sound attenuation and respect for the air flow of the device.
Our sound boxes have been tested by the LNE, National Metrology and Testing Laboratory, and an average attenuation of 5dB has been observed on the most common configuration.
This is a significant result but not a miracle solution that would completely confine the noise. This solution exists but it would not allow the outdoor unit to operate correctly.
On the other hand, our boxes are designed to attenuate what generates the strongest sound pressure on a group, namely the compressor located on the right of the device. Our solution only slightly affects the sound produced by the fan(s).
As acoustics is not our primary business, no quantified commitment in terms of sound reduction (dB) will be made. Our feedback is conclusive, but a quantified reduction or a commitment to results would require an in-depth study of the equipment (sound power, acoustic pressure), of the environment in which it is located (effect of reverberations, partitioning, vibrations, etc.). ) and this is not within our scope.
