FAQ-e009 : What kind of terminal does the App run on? Are there any Apps that run on Android devices?
[Answer] Yes, it is normal operation.
”Low Frequency Detector” app measures the sound level of the very low frequency band below 100 Hz.
The reference tone signal (1kHz) is output from the built-in speaker during the low-frequency sound level measurement. This app collects both the reference tone signal and the ambient sound at the same time, and analyzes the collected sound data to detect its low frequency component. The detection level is a relative level to the reference tone signal. Therefore, please be sure to set the playback level and calibration at the first boot.
