Directional Sound Source

The Directional Sound Source Model BAS003 is designed to generate homogeneous sound fields using random noise in compliance with the following standards: Building acoustics (insertion loss, acoustic absorption area, etc: ISO 140-3, ASTM E90, ISO 140-5, ASTM E966). The BAS003 is typically used to generate a noise in a free-field for the evaluation of the transmission loss index of a façade. The available high-efficiency power amplifier, BAS002, is light and can be remotely controlled for easy use in the field.

Highlights

• Used for ISO 140-3, ASTM E90, ISO 140-5, ASTM E966 compliant measurements
• High sound power output level
• Insertion loss of Noise Barriers
• Available lightweight & compact amplifier (BAS002E/U)
• Shipping case standard

Applications

• Architectural Acoustics: In-situ Façade Measurements
• Building Acoustic Measurements
• Sound Insulation
• Evaluation of the Acoustic Indexes for the Transmission Loss of Façade
