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:
- For all-round acoustic measurements in temperatures up to 125 °C; typical applications include interior and exterior vehicle acoustic measurements - and sound power
- Well suited for when low-frequency disturbance, such as body boom or road noise, needs to be eliminated
- For measurements in confined spaces or building an array with a low noise floor
- 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.
