Qam

Smart DSP Signal Generator and Measurement Amplifier

The Qam power amplifier provides a very high power/weight ratio for maximum portability. The internal firmware and DSP allow a very flexible use with different sound sources. The button controlled operation is fast, straightforward and stable. Application dependent, internally generated white/pink noise, sine sweep and pulsating noise signals are available as well as acceptance of any external signal generator. Especially for measurement in difficult small spaces, a low frequency third octave band equalizer allows adaption to the measurement space. Remote activation and de-activation up to 100m. range in free sight.  Equalization is available for the Infra-Qsources sound sources and up to 10 settings per type of sound source can be stored for standardized measurements

Qohm

Omni-directional sound source

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 Qohm 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 subwoofer is not needed for all common measurement situations.

Qoms1

Monopole omni-directional hemisphere sound source

Qoms1 is a unique small and lightweight hemisphere monopole point source for broadband measurements. Similar to its fully omni-directional variant Qoms2, the Qoms1 sound source can be used for acoustic optimization of performance sites such as theaters,schools or religious sites for speech and music.

Qoms2

Monopole omni-directional sound source

Qoms2 is a next level monopole point source for broadband measurements with high accuracy. Measurements such as room impulse responses, Speech Transmission Index (STI) and reverberation time allow consultants to optimise the acoustics of performance sites such as theaters,schools or religious sites for speech and music. The exact identification and optimization of early and late reflections allow acoustic experts the correction and optimisation of existing sites. The reliable measurements from Qoms2 can be used to correlate and improve the acoustic models with the purpose of supporting healthy acoustics of new projects already in the design phase.

Qref

Extreme Lightweight Sound Power Reference Source

Qref is a unique sound source for regular verification of acoustic rooms for product testing, machinery testing, anechoic rooms, reverberant rooms. Another main application for this product is sound power identification on-site of for example installed machinery or larger installations. The small size, weight and signal control on the Qsources Qref make it specially suitable for is this type of sound power identification in difficult spaces.

Qmir

Miniature Sound Power Reference Point Source

Qmir is a very compact power reference monopole source with high acoustic impedance. The small size of the Qsources Qmir make it especially suitable as a reference for large-count antenna measurements. The 20.5 mm. diameter allows a verification of the geometrical resolution down to ± 3cm. Next to this, the soundpower proportional signal allows a unique verification of the level identification through the antenna sensors, hardware and software processing.
