    Acoustics is the science of sound. A good solution to reverberation often requires on-site acoustic measurement by an acoustic specialist.

    An acoustic specialist comes to your premises. Using special measuring equipment, we investigate whether there are poor acoustics.

    On the basis of this measurement, you will receive advice directly on site. With EASY Noise Control, you are assured of good acoustics.
