Brand LARSON DAVIS (a part of the PCB PIEZOTRONICS)

Omnidirectional sound source Larson Davis BAS001 is designed to generate omnidirectional sound fields for making standard compliant measurements including: reverberation time (ISO 3382, ASTM E2235), building acoustics (insertion loss, acoustic absorption area, etc: ISO 140-4 ISO 140-3, ASTM E336, ASTM E90, DIN 55 210).

• Used for ISO 140-4, ISO 140-3, ISO 3382, DIN55210, ASTM E90, E336, E2235, C426 compliant measurements
• High sound power level output
• Acoustically Isotropic Source
• Available lightweight & compact amplifier (BAS002E/U).

When coupled with the Omnidirectional sound source BAS001 or Directional sound source BAS003, the Sound source speaker amplifier Larson Davis BAS002 is the ideal sound source for making room and building acoustics measurements.

• 500 W Output Power
