Product Description
Test standard：
Foreign test standards ：ASTM E2611 & ISO3744
Domestic test standards ： GB/Z 27664-2011
****Requirement****：
Low background noise requirement: due to the high sound insulation of duct wall;
Test environment: the test must be done in a anechoic chamber.
Product testing principles and functions：
1)PSA/VW test requirements: make an assessment on duct sound insulation performance for different supplier；
2)Test service: Supports material-based duct radiated noise test;
Data output: narrowband spectrum, 1/3 octave outputs
3)File output format: txt and excel;
4)CAE Modeling verification: verify the accuracy of Duct CAE model;
5)Duct configuration：
Fiberboard duct, plastic duct, rubber duct, FIBERGLA duct, other non-metallic duct;
Thin-wall metal duct system.
6)Customization: software/hardware, acquisition.
