Omnidirectional, Dodecahedron Sound Source

Building and Room Acoustics | Model BAS001

BAS001 omnidirectional dodecahedron sound source for building and room acousticsThe Dodecahedral Sound Source Model 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). 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.
