New range of microphones designed for high-precision, free-field measurements and ideal where a microphone with high sensitivity is required.

May 27 2020

To help engineers and acousticians achieve accurate measurements in their everyday tasks, Bruel & Kjær has introduced the Type 4966 family of robust, reliable, free-field microphones ideal for high-precision acoustic measurements.

The family includes four carefully selected types suitable for different applications. There is a model for all-round acoustic measurements in temperatures up to 125°C; typical applications include interior and exterior vehicle acoustic measurements - and sound power. Another version is well suited for when low-frequency disturbance, such as body boom or road noise, needs to be eliminated. There is also a model for measurements in confined spaces or buildings with a low noise floor and another for high sound pressure level (SPL) measurements or if the integrity of the microphone measurement channel needs to be checked

Just like every Bruel & Kjær microphone, the entire production process of the Type 4966 family is done by hand and controlled by tight tolerances, making certain that each microphone meets the highest standards.

Assembly takes place in an ISO Class 5 clean room, ensuring that the microphones maintain their low noise floor and high stability even in environments that combine high humidity and high temperature.
