VSS15 Plane Volume Source

VSS15 is a special plane volume source developed by BSWA TECH. It can be used in noise transfer function (P/F) and acoustics transfer function (P/Q) reciprocity test, TPA analysis, acoustic excitation test such as sound insulation, sound absorption and SEA test.

The VSS15 is made with twelve loudspeaker units with 100 Hz to 8000 Hz frequency response. The maximum output sound power level is up to 123 dB. The built-in reference microphone can self-calibrate the sound power output. When you need a larger sound source for your application, the modular design can help you to easily combine several plane volume sources into a large sound source.
