When you need to know a headphone produces an expected output but don't need to measure human perception, the Headphone production test fixture Larson Davis AEC210 is an ideal solution.

Thanks to flush-mounted microphones and configurable positioners, Model AEC210 produces repeatable measurements that are well suited for quality testing during production.

• Accurate headphone positioning for repeatable measurements
• Includes ICP® microphones
• Highly configurable mounting platform
• Sound source speakers available for external sound or artificial mouth
• Cost effective solution for quality testing
• Compatible with off the shelf audio interface and software.

Omnidirectional sound source Larson Davis 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).

• 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).

When coupled with the Omnidirectional sound source BAS001 or Directional sound source BAS003, the Sound source speaker amplifier Larson Davis BAS002 is the ideal sound source for making room and building acoustics measurements.

• 500 W Output Power
• 5 Hz to 60 kHz bandwidth
• THD + N <0.12%
• Remote Control.

Directional sound source Larson Davis 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).

• 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.

Impact noise source tapping machine Larson Davis BAS004 is used to simulate foot fall noise in a manner that is well controlled and reproducible so that measured results can be replicated and compared with other measurements.
