Brüel & Kjær 4966-H-041 Microphone W/ Transducer Electronic Data Sheet

The Brüel & Kjær 4966-H-041 Microphone with Transducer Electronic Data Sheet, or TEDS Microphone, is a cartridge and a preamplifier assembled sealed in a clean environment.  Type 4966 is suited for free‐field measurements where a high-sensitivity pre-polarized microphone with a full 20 kHz bandwidth is preferred. The assembly has one type and serial number. Individual TEDS microphone information is programmed in a data chip inside the preamplifier. The Brüel & Kjær 4966-H-041 microphone is available with CCLD as well as classical preamplifiers. TEDS is standardized in compliance with IEEE 1454.4.

The most important benefit of the Brüel & Kjær 4966-H-041 microphone is that the actual identity and loaded sensitivity of the cartridge are programmed in the TEDS -- they are readily available for documentation and application purposes. For many Brüel & Kjær 4966-H-041 microphones, the individual frequency response is stored on a mini‐CD under the S/N ratio of the microphone. During the manufacturing process, the unit is sealed in a clean environment, thus eliminating contamination that could later result in reduced performance.
