Acoustic testing is an important part of certification for telecoms equipment. Using a variety of methods to characterize sound quality and volume, Element’s acoustic services are designed to meet the requirements of markets around the globe.

Element provides testing for both regulatory and conformance requirements of telecom equipment. We can test a range of product types, including hands-free equipment (conference telephones), modern headsets, head-worn headsets and in-ear headsets.
