CAPABILITIES

Excellent amplitude and phase matching over wide ranges of temperature and humidity phase response
Excellent long-term stability through artificial aging and clean room assembly guarantee excellent long-term stability and low noise even in harsh environments
Side vented for pressure equalization.
The microphone does not need an external polarization voltage, thus enabling the use of inexpensive 2-wire system (CCLD) input.

Prepolarized Free-field Microphone Type 4954 has been optimised for a flat, free-field response and is suited for measurements far beyond the audible range. Due to its wide frequency range, the frequency response in the audible range is typically within ±1 dB.
