BAS001 omnidirectional audio source

I. Specification of BAS001 omnidirectional audio source

• The BAS001 sound source is commonly used to saturate a room with a uniform sound field. High efficiency power amplifiers are available with no fan for cooling, allowing measurements in quiet environments, such as in reverberation time applications. The included carrying and shipping case is designed to provide reliable protection for the BAS001 bifacial loudspeaker under demanding conditions for many years.
• Pairing the Larson Davis Model 831 sound level meter with the optional Echo Reverberation Time (831-RT) assists you in a variety of architectural acoustics applications ranging from simple experimental reverberation times to room performance, to the calculation of the absorption coefficient for the material performance. Most of the time, these measurements are regulated by various international standards.

• The Model 831 measures decay and then calculates the reverberation time according to ISO 3382-2 or ASTM 2235-04. When using the Disruptive Noise method, the Model 831 not only enables data collection, but can also use the built-in Noise Generator to control an omnidirectional sound source. Recent trends suggest that the Integrated Pulse method is gaining popularity and the Model 831 handles the collection of decays and subsequent T20 or T30 calculations with complete and ease.
  • Used for ISO 140-4, ISO 140-3, ISO 3382, DIN55210, ASTM
  • Measurements comply with E90, E336, E2235, C426
