Type 4944 is a ¼-inch Prepolarized Pressure-field Microphone designed for high-level and high-frequency measurements over a frequency range of 4 Hz To 70 kHz.
FAMILY 4944
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
