Omnidirectional sound source BAS001

Highlights - 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) Applications - Room Acoustics: In-situ Reverberation Time Measurement - Building Acoustic Measurements - Sound Insulation - Evaluation of the Acoustic Indexes for the Transmission Loss of Horizontal or Vertical Partitions - Sweep Response Technique BAS001 Omnidirectional Source The BAS001 Source 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). The BAS001 is typically used to saturate a room with a uniform acoustic field. The available high-efficiency power amplifier has no fan for cooling, allowing measurements in quiet environments, like those in reverberation time applications.
