Method of Testing of Sound Absorption Properties of Materials Intended for Ultrasonic Noise Protection
Efficient ultrasonic noise reduction by using enclosures requires the knowledge of absorbing properties of materials in the frequency range above 4 kHz. However, standardized methods enable determination of absorption coefficients of materials in the frequency range up to 4 kHz. For this reason, it...
