This new version is a combination of a ½-inch prepolarized pressure-field microphone cartridge (Type 4971) and a high temperature ½-inch Constant Current Line Drive (CCLD) preamplifier, which connects to CCLD input conditioning, thus ensuring all measurements can be conducted using a general data acquisition system.
Type 4971-H-041 is optimized for use in pressure-field applications, such as with couplers measuring close to audio device sound ports or flush-mounting.
It’s also suitable for random incidence measurements and free-field measurements with 90°C incidence. This makes it ideal for measuring moving objects like trains or planes, as – even though the object is moving – the frequency characteristics remain the same.
The microphone’s wide frequency range (5 Hz to 20 kHz, ±2 dB), broad dynamic range (20 dB(A) to 146 dB) and immunity to harsh, unpredictable environments also makes it suitable for component testing within the telecom, audio, automotive and aerospace industries.
