Low Frequency Detector is a Utilities app by TOON,LLC. "Low Frequency Detector" is a new acoustic measurement tool for detecting the low frequency sound that is hard to hear in the normal situation. The human ear is insensitive enough to become a low frequency.

APK (Android Package Kit) files are the raw files of an Android app. Learn how to install low-frequency-detector.apk file on your phone in 4 Simple Steps:
Yes. We provide some of the safest Apk download mirrors for getting the Low Frequency Detector apk.
1. - The sound measurement of the low frequency range is a level difference with respect to the reference signal (1kHz sine wave), which indicates the relative power level.
2. 1) Calibration (Calibrate): A reference signal (1kHz sine wave) is output to determine the reference noise level for the low frequency component.
3. - Low frequency power level measurement less than 100Hz (LF Level): Flat characteristic, Updating indication of measurement period 1 sec.
4. - Leq (dB): Sound power level with the frequency weight characteristic Z (Flat) of the audible band.
5. 2) Measurement (Measure) : Analyze a power level of low frequency sound.
6. By depending on its frequency component and sound level, it is different the degree of influence on the human body and the noise sensation.
7. - Low frequency (LF) Level (dB): Time course graph with peak level noise level judgment (RED-very noisy, YELLOW-noisy, GREEN-normal) at the peak level.
8. 3) Measurement display: It can select either 1/3 octave band frequency analysis, FFT analysis or Time course graph.
9. - Since iPhone's built-in microphone has a lower sensitivity on the very low frequency range, it is not recommended to measure a huge volume sound near a very loud noise source.
10. - Power level measurement in the audible band (Leq): Flat characteristic, Updating indication of measurement period 200ms.
11. - The reference signal is output during calibration and sound level measurement.

It cannot detect 120 Hz or above because it is outside the range, and 20 Hz and below seems to get lost in the background noise. Both 30 Hz and 110 Hz are detected.
This app had a slight learning curve, but it’s well designed to lead one through what to do. It’s easily well-calibrated enough for my purposes, and getting it to work with the tiny Android mic was ingenious. Extremely worth the value. Update: I realized after I wrote the above that it almost looks like a fake review. I’m a meditator who is very sensitive to sound in the environment. LF sound is hard to localize, but I was able to use this app, in addition to my other senses, to walk around and eventually find many intermittent LF sources in my vicinity, made easier by the multimodal sharp peaks in the FFT when I got closer to and farther from different sources.
