B&K TYPE 4948 Surface Microphone

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.

Description

Type 4948 is a 1/2″ CCLD surface microphone intended for use on airplane surfaces during in-flight testing. The microphone is also well suited to wind-tunnel testing, limited spaces, or near to hard reflective surfaces.

  • Measurement of sound pressure on surfaces
  • Acoustic fatigue testing of airplanes
  • Wind-tunnel measurements
  • Medium- to high-level measurements
  • Measurement in confined spaces
The microphone offers high mounting flexibility and its diaphragm is flush with microphone housing in order to minimize the effect of wind-generated noise on the microphone.
