Acoustic Test Enclosures for Buzz, Squeak, and Rattle (BSR) Testing
BSR testing identifies unwanted noises in vehicles that may be annoying or distracting to users.
Tests are performed on full vehicles, sub-assemblies, or individual components using both subjective evaluation and objective sound quality metrics like loudness, tonality, and roughness. IAC Acoustics enclosures ensure low noise floors for repeatable, accurate BSR testing.
Quiet Shaker Testing
Quiet shakers vibrate parts or assemblies to detect BSR events without adding background noise.
These systems must be low-noise, lightweight, and rigid to prevent interference. IAC solutions support precise testing by minimizing signal-to-noise issues and enabling reliable sound quality assessments.
