Using the Low-Noise Microphone UC-35P together with the RIONOTE as frequency analyzer makes it possible to perform frequency analysis (FFT analysis and octave band analysis) of very low-level sounds in an anechoic chamber.
Sound pressure levels from 10 to 90 dB※ in the frequency range from 10 Hz to 12.5 kHz are supported.
※A weighted: typ. 2.0 dB、C weighted: typ. 6.0 dB、Z weighted: typ. 23.0 dB
