Low Frequency Detector - A Tool to Detect Low Frequency Sound
"Low Frequency Detector" is a useful acoustic measurement tool that helps you detect low frequency sounds that are difficult to hear in normal situations. This app has been developed by TOONLLC and is available for iPhone users in the Utilities & Tools category. If you are exposed to noise from neighboring constructions and factories without even realizing it, you may feel bad and oppressed. This app can help you detect what type of low frequency noise exists with simple operation.
Low frequency sounds are sound waves with a frequency range of 1 Hz to 100 Hz. Depending on their frequency component and sound level, they can have different degrees of influence on the human body and noise sensation. The "Low Frequency Detector" app can examine the frequency component of low frequency sounds using 1/3 octave band analysis and FFT analysis.
This app comes with several features that include low frequency power level measurement less than 100Hz (LF Level), power level measurement in the audible band (Leq), 1/3 octave band analysis (OCT), FFT analysis (FFT), time course graph (TIME), snapshot (Snap) on the measurement display screen, and a report function (Report) that provides an analysis report of a peak LF level with TIME, OCT, and FFT. It also allows users to measure sound for up to 60 seconds.
