Acoustic Audio Testing System
The Acoustic Audio Testing System is a comprehensive tool used to measure and analyze the acoustic properties of audio materials, primarily including absorption coefficient, acoustic impedance, and air permeability. The system utilizes impedance tubes, sound sources, microphones, and other equipment to test the material’s response to sound waves across a wide frequency range. This allows for evaluation of its performance in applications such as building acoustics, industrial noise control, audio equipment development, and environmental noise assessment. The system provides high-precision measurement data and detailed analysis reports, helping users optimize material selection and design to enhance acoustic performance and noise control effectiveness.
