VSS15 Planar 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 features twelve loudspeaker units, with an effective frequency range covering 100 Hz to 5 kHz. It can achieve an output sound power level of up to 123 dB. An integrated reference microphone is used for feedback on the output excitation sound power. The product is equipped with vibration-damping feet at the bottom and assembly holes on the side, allowing multiple planar volume sources to be combined for use.
