Use Scenarios

In Brüel & Kjær hand-held and foldable arrays

Type 4959 microphones have good, stable amplitude and phasematching over wide ranges of temperature and humidity. Their frequency response is optimised for a flat response in a pressure field.

Each microphone’s built-in TEDS (Transducer Electronic Data Sheet) contains information about the complex transfer function, enabling applications to use data for individual transducers, resulting in more precise measurements.

The preamplifier is an industry standard DeltaTron (constant current line drive) type, allowing the use of the same coaxial cable for signal, power supply and TEDS.

A rugged protection grid provides an integrated heat shield. The microphone is front-vented for pressure equalization.
