Acoustic and Vibration Performance Testing
category
Acoustic and vibration testing evaluates textile noise absorption, sound transmission loss, vibration damping, and structure-borne sound isolation properties using impedance tube, reverberation room, and vibration excitation methods that quantify the acoustic performance of textile materials in building, automotive, and noise control applications.
Role
Enables engineering of high-performance acoustic textiles for automotive interior noise reduction, architectural sound absorption, and industrial noise control, providing the standardised absorption coefficient and transmission loss data required for building regulation compliance and vehicle interior acoustic design.
