The foam is easy to process and contributes to both outstanding acoustics and, thanks to its fire resistance, a high level of fire safety. “Owing to its very good absorption figures in the 500 to 5,000 Hz frequency range, we successfully use Basotect melamine foam as a passive sound absorber,” says Prof. Dr.-Ing. Christoph Kaup, managing director Howatherm Klimatechnik. “Together with the active electroacoustic component, this material makes a crucial contribution to improving the sound damping values in the ‘Acoustic Unit by Howatherm‘ system.” For active sound cancellation in the lower frequency range below 125Hz, the electroacoustic component emits a sound with a wavelength that superimposes the targeted existing sound wave in such a way that, ideally, the two waves cancel each other out. This system is used in specialty air conditioning equipment that is installed in buildings with stringent sound absorption requirements, such as theaters, concert halls, galleries and other venues in which acoustics may be of critical importance. Specialty air conditioning equipment influences ambient air by controlling temperature, humidity and air quality. This equipment fosters both air exchange and thermal air treatment in rooms and buildings.
