Helping Microsoft to perfect sound quality

microsoft, usa


Sound quality holds the key to Microsoft’s vision of the future, and since their engineers always want the best equipment on hand, they built a series of anechoic chambers that includes the quietest place in the world – equipped with the very best kit.

Microsoft® has a vision to make our devices so effortless to use that they all but disappear, and natural language interfaces are a major part of making it happen. But to develop and test the necessary components and algorithms, Microsoft’s world-leading engineers need test equipment that maximizes the signal and minimizes the noise to perform the most valuable, repeatable and purest measurements possible.


To develop technological devices with class-leading sound quality and human factor design, including effective voice recognition technology

Anechoic chambers for testing precise sound levels, equipped with a range of Brüel & Kjær microphones and preamplifiers, head and torso simulators, and mouth simulators

World-leading product sound quality thanks to repeatable quantification of audio performance at a finer level of detail.



Microsoft Corporation is an American multinational technology company that has been a key player in the computer industry since its founding in 1975. Headquartered in Redmond, Washington, Microsoft initially gained dominance in the operating systems market during the 1980s and ’90s with MS-DOS and Windows. Its strong market position eventually gave rise to the company’s diverse and extensive range of technological offerings, from personal computing and entertainment to enterprise cloud computing and artificial intelligence.
