By using an omni-directional source, users don't have to place the speaker into multiple positions and take multiple measurements as it allows to uniformly radiate sound in all directions. The measurement can be conducted very fast and accurately at high broadband output levels (122 dB Lw for Qohm).
Another advantage of using Qohm is that no subwoofers are needed and it offers the highest quality in material within the smallest dimensions and extreme lightweight. This means that the product can easily be taken on-site by only one single consultant. 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.
Qsources Qohm sound sources also enable to perform acoustic tests related to sound propagation between rooms such as e.g. transmission loss testing of insulation or measuring the Absorption coefficient or reverberation time. Qohm has been designed to fulfil ISO 140-3 Annex C (Laboratory measurements), ISO 140-4 Annex A (Field measurements) and the ISO 3382- 1 Annex A (Reverberation Time measurements).
The Qohm sound source has been designed to use with Qam Power Amplifier for guaranteeing optimal power output without damaging the speaker.
