Normal incidence acoustic measurement system 9301_9302

• 

Features

The 9301 and 9302 are systems for measuring sound absorption and transmission loss of materials using acoustic tubes.
While some large-scale test facilities such as a residual classroom may be required to measure sound absorption coefficient and transmission loss, this system makes it possible to determine the sound absorption coefficient and transmission loss of materials without the use of such large-scale test facilities.
This system enables measurements in accordance with JIS A1405-2 and ISO 10534-2.
It can be used to speedily carry out evaluations of materials such as automobile and building interior materials.
