Offering Acoustic Test Chamber. This includes a precision-grade, double-walled hemi-anechoic chamber for product noise emission testing and other acoustic research/testing requiring an acoustic free-field over a reflecting plane isolated from background noise. Equipment available for use in chamber includes a multiple-channel simultaneous data acquisition system, automated microphone and specimen positioning systems, signal generators, and sound sources. The chamber is qualified for testing as meeting or exceeding requirements of accredited test standards.Types of testing commonly performed in the hemi-anechoic chamber include: product noise emission testing (including sound power determinations, operator/bystander sound pressure level measurements, prominent tone evaluation, loudness calculations, and advanced sound quality analysis), waveform recording from microphones, or binaural recording/analysis. The extremely low-noise and free-field environment also allows for testing audio component frequency response, directionality response, and signal fidelity. Aural non-detectability of military devices (per MIL-STD-1474D) is also available. The hemi-anechoic chamber is easily configured for client testing requirements, including data lines, electric power, air supply/exhaust, etc. A large acoustically-isolated control area adjacent to the chamber allows incorporation of any client-supplied equipment into the test program if needed.
