Special Microphones

Special microphones designed for specific measurement applications. Brüel & Kjær provide four special microphone types ranging from outdoor microphones, surface microphones, array microphones, and probe microphones. Each microphone provided with ranging adaptability for specific environments and measurement conditions.

TYPE 4178

1/4" Sound Intensity Microphone Pair, Ext. Polarized

Sound Intensity Microphones specially designed for high level and high frequency measurements over a frequency range of 4 Hz to 100 kHz, with broadband matching of phase responses.
TYPE 4197

½-inch Microphone pair for Sound Intensity

Phase-matched pair of ½-inch microphones, designed for being used with Brüel & Kjær’s range of sound intensity analyzers.
TYPE 4948

Aerospace Surface Microphone

Surface Microphone Type 4948 is designed to be used in aerospace. For example, on airplane surfaces during in-flight testing and is also well suited to wind-tunnel testing, limited spaces, or near to hard reflective surfaces.
TYPE 4948-B

Aerospace Surface Microphone

Surface Microphone Type 4948-B is designed for measuring airplane surfaces during in-flight testing. The microphone also well suited to wind-tunnel testing, limited spaces, or near to hard reflective surfaces, and is supplied with two coaxial cables and CIC.
TYPE 4949

Surface Microphone For Automotive Applications

Automotive surface microphone designed for measurement of the true surface pressure. Ideal for mounting directly on the car surface during wind-tunnel tests and for measuring in confined spaces.
TYPE 4949-B

Automotive Surface Microphone

Automotive Surface Microphone with two coaxial cables and CIC, designed for measurement of the true surface pressure, especially in automotive applications. It is well-suited for mounting directly on the car surface during wind-tunnel tests or for easy measurement in confined spaces.
TYPE 4952

Outdoor Microphone For Long-term exterior use

Outdoor Microphone Type 4952 provides class 1 compliant outdoor sound measurement in compliance with IEC 61672. The microphone is built from polymer materials, protecting the microphone from changing weather in longer periods of outdoor use.
TYPE 4957

10 KHZ Array Microphone

Array Microphone for use in systems requiring a large number of microphones, for example, beamforming arrays, STSF measurements, and non-stationary STSF measurements.
TYPE 4958

Array Microphone for 20 KHZ

Precision array microphone for STSF measurements, non-stationary STSF measurements and beamforming arrays.
TYPE 4959

Short Array Microphone for 20 kHz, Prepolarized

Short array microphone designed for use in our hand-held and foldable microphone array systems.
TYPE 4198

Weatherproof Outdoor Microphone

Outdoor Microphone Type 4198 is built specifically for unattended, semi-permanent outdoor installations; noise control, complaint investigation, and general outdoor research.
TYPE 4182

Probe Microphone

Probe Microphone - 1 Hz to 20 kHz, 200 V polarization - for near-field sound pressure measurements in places with limited space, or in harsh environments where a conventional microphone would be unsuitable.
Type 4184

Weatherproof Microphone

Weatherproof microphone with exceptional omnidirectional characteristics. Type 4184 is an external microphone designed for use in permanent or semi-permanent outdoor noise monitoring.
