Free Sound Field TEDS Low Noise Microphone Model 4955
A system with high sensitivity, excellent long-term stability, and outstanding corrosion resistance.
1-inch and 1/2-inch microphones adequately cover many noise measurements based on IEC, ISO, and ANSI standards, but there is a growing demand for noise measurements at levels lower than these noise floors. In such cases, Brüel & Kjær's Type 4955 is the optimal choice. It combines a total titanium laser-welded diaphragm and a 1/2" microphone cartridge with optimized self-noise, along with a low-noise preamplifier with a gain of 20dB. As a result, this system is highly sensitive, with excellent long-term stability and outstanding corrosion resistance. The 4955 TEDS microphone has a representative noise level of 5.5dB A-weighted sound pressure level, allowing it to adequately measure up to 10dB A-weighted sound pressure levels. ● For more details, please download the catalog or contact us.
