B&K Type 4966 Microphone

Meet Type 4966 - our New Microphone Family

New microphone family - handmade in Denmark. Designed for high-precision, free-field measurements, where a microphone with high sensitivity is required.

To help engineers and acousticians achieve accurate measurements, Bruel & Kjær has introduced the Type 4966 Microphone family. Four new microphone types, designed for robust and reliable free-field measurements, are ideally suited for high-precision interior and exterior vehicle measurements, and sound power measurements. 

Type 4966 introduces four microphone types suitable for:
  1. All-round acoustic measurements in temperatures up to 125°C
  2. Eliminating low-frequency disturbance, such as body boom or road noise
  3. Measurements in confined spaces  or when building an array with a low noise floor
  4. High sound pressure level (SPL) measurements or if evaluating the integrity of the microphone measurement channel
Just like every Bruel & Kjær microphone, the entire production process is done by hand and controlled by tight tolerance. Assembly takes place in an ISO Class 5 cleanroom ensuring that each microphone meets the highest standards, provides a low noise floor and high stability – even in environments with high humidity and temperature.
