BAS001 Omnidirectional Source Omnidirectional (Dodecahedral) Sound Source for Reverberation Time, Room Acoustic and Building Acoustic Measurements Highlights I 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) 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 The BAS001 Source is designed to generate omni-directional 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 highefficiency power amplifier has no fan for cooling, allowing measurements in quiet environments, like those in reverberation time applications. Larson Davis
