1/4" PRESSURE-FIELD MICROPHONE, PREPOLARIZED
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.
TYPE 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

The shape of the microphone front ensures excellent microphone performance when flush-mounted. The laser-welded diaphragm on the microphone housing ensures that the sensitivity is resistant to rough handling during flush mounting.
The sensitivity can be calibrated at 250 Hz using Pistonphone Type 4228 with ¼-inch Adaptor DP-0775. The pressure-field response can be measured using Actuator UA- 0033 with Adaptor DB-0264. The pressure-field response is equal to the actuator response.
