Headphone Testing Advances A Generation

Headphone Testing Advances A Generation
As thee headphone market expands rapidly, advances in technology have allowed for the production of high definition headphones in more than a wide range of types and forms, and have improved performance and connectivity. Meeting the expanding requirements of headphone users, G.R.A.S. introduces what it describes as the next generation of headphone testing technology. The technology features an improved pinna and a low-noise ear simulator that is compatible with the IEC-standardized KEMAR and the portable 43AG ear and ch remarkable improvements for research and test engineers. The low noise ear simulator brings the noise floor down below the threshold of human hearing, so it is possible to capture everything users can perceive. At the same time it increases the upper frequency limit from todays 711 coupler from 10 kHz to 20 kHz. To find out more, visit http://www.gras.dk/next-generation-headphone-testing G.R.A.S.
