For applications measuring infrasound (below the human hearing threshold) microphone model 378A07 provides the capability to measure to 0.1 Hz (-3dB).
over 136 dB or above 20 kHz. This microphone is a cost effective alternative to a ¼" microphone and preamplifier combination and has a much lower inherent noise.
Common applications for this high amplitude, high frequency microphone include environmental monitoring, railway testing for
over 136 dB. The 377A21 measures up to 160 dB (147 dB with a standard preamplifier) in a ½" package, while maintaining a 19 dBA noise floor. This microphone is a cost effective alternative to a ¼" microphone and preamplifier combination and has a much lower inherent noise.
