VSS058 Low Frequency Volume Source
Low frequency volume source is omni sound source of volume acceleration which source diameter must be close to the wave length.
VSS058 low frequency volume source was developed by BSWA for reciprocity method of noise transfer function or acoustic transfer function reciprocity test, TPA (Transfer Path Analysis) test and acoustic excitation test such as sound insulation test, material absorption coefficient test, SEA (Statistical Energy Analysis) test. The frequency response can cover 50Hz to 800Hz. The sound pressure level at 1 meter away is up to 98dB.
VSS058 embedded an internal reference microphone to monitor the volume acceleration output. The reference microphone is pre-polarized microphones MPA251 which can be calibrate by CA111 sound calibrator.
VSS058 has a high power loudspeaker. The output power level is up to 200W continuous. The metal shield before loudspeaker can protect again the damage to diaphragm
