The European heat pump market has seen remarkable growth, with over 2.17 million units sold in 2021 alone, marking a milestone in the transition toward energy-efficient and environmentally friendly heating solutions. However, as heat pumps gain popularity, their low-frequency noise remains a major concern for users, especially at night. This issue has prompted the Dutch government to implement stricter regulations requiring outdoor heat pump units to maintain noise levels below 40 dB(A) at property boundaries.

Noise is a significant barrier to heat pump adoption, with many consumers hesitating due to concerns about sound pollution. ATA Mute addresses this critical issue with advanced noise reduction technologies tested on both heat pump and ventilation systems, ensuring compliance with regulations while enhancing user comfort.

Our Comprehensive Solutions Include:

1. Silent Fans
   We design silent fans with innovative features that achieve up to 15 dB SPL noise reduction. These fans minimize low-frequency noise as a broadband passive solution, tackling one of the main sources of disturbance in heat pumps.

2. Acoustic Tape and Panels
   Our ultra-thin acoustic tape (<1mm) and thin panels (<10mm) can be seamlessly applied to the casing of heat pumps and ventilation systems. These materials effectively absorb low and high frequency noise and vibrations, ensuring quieter operation without increasing system size or compromising efficiency.

3. Acoustic Compressor Jacket
   The highlight of our solutions, the Acoustic Compressor Jacket, is designed to wrap around the compressor, absorbing noise before it propagates. With a thickness of just 1 cm, the jacket reduces 19dB tonal noise of the compressor in the critical low-frequency range below 200 Hz and the heat pump noise power level reduces by 4–6 dB. It boasts an absorption coefficient of 50%, making it highly effective while maintaining a compact design.

4. Exhaust Mufflers
   Our lighter, shorter exhaust mufflers respect to the traditional ones, offer noise reductions of 15–30 dB, making them ideal accessories for enhancing the acoustic performance of heat pumps and ventilation systems.

These solutions have undergone rigorous testing in real-world scenarios, delivering impressive results for both heat pumps and ventilation systems. By significantly reducing noise, ATA Mute enables heat pumps to comply with regulations, ensuring their vital role in the global energy transition.
