The highly uniform sound radiation from the Qohm source allows controlled excitation of the acoustics of small and large sites, such as classical theaters, factory halls, schools, offices, apartments and machinery rooms.
Thanks to the omni-directionallity of the sound source, as specified in ISO 16283, only a few measurement locations are needed in each space for typical airborne isolation and reverberation testing. The extreme light weight of 3.1 kg. and small dimensions allow fast and efficient work by a single consultant.
With the smooth broadband spectrum at 122 dB Lw the level is more than sufficient from 50 to 16000 Hz. A high output at 50 Hz, 97 db Lw, also means that a separate sub-woofer is not needed for all common measurement situations. Qsources Qohm sound sources are a must for every acoustic industry professional who wants to perform acoustic tests of rooms to make recommendations on placement of absorption materials creating the correct acoustic balance or to test the acoustical properties of a building materials.
It is advised, but not obligatory, to combine the Qohm with a Qam power amplifier for maximum performance and reliability.
