Prepolarized ¼″ Pressure-field Microphone Type 4944 is specially designed for high-level and high-frequency measurements. By using new materials and a new way of mounting the diaphragm, the microphone is geared to withstand rough handling. The assembly of the microphone in a clean room environment ensures that the microphone can be used in high-humidity environments and still produce reliable results. Type 4944 can be used with sound level meters to measure high sound pressure levels

  • High-level measurements
  • High-frequency measurements
  • Flush mounting
  • In small closed couplers, close to hard reflective surfaces or flush-mounted
  • The sensitivity has been optimised to allow measurements of high sound pressure levels without clipping in the built-in CCLD preamplifier.
