Acoustic performance tset
Acoustic performance (sound insulation sound absorption coefficient,free sound field size,noise floor) test is one of the professional testing capabilities of our company,s acoustic testing department. After years of development, we have a professional material acoustic performance testing team.Measure the configuration of the domestic advanced testing equipment and testing environment, such as built up to the standard of ISO/GB and other international and domestic professional semi-dead room, half ring room, reverberation room, acoustic room (the sound source room and reception room), on the basis of the ISO/IEC 17025:2005 standard requirements, the establishment and operation of quality system, as a third party laboratory, can according to the technical requirements of the standards at home and abroad, carry out material lab and field acoustic performance (noise test).
Laboratory acoustic performance testing project
Air sound insulation, standing wave tube sound absorption coefficient, reverberation chamber sound absorption coefficient
Field acoustic inspection items
Environmental noise detection:nuclear power plant environmental assessment noise,industrial enterprise boundary noise, construction site boundary noise,railway boundary noise,urban area environmental noise and vibration;
On-site sound insulation testing of buildings and components: indoor air sound insulation, floor air sound insulation, floor impact sound insulation, exterior air sound insulation, window air sound insulation; Sound insulation interval performance, hall reverberation time;
