Sound Analyzer App
By Dominique Rodrigues
Sound Analyzer App enables you to use your smartphone as a Sound Level Meter (SLM) and a Real time Audio Analyzer (RTA). Environmental noise, measured in decibel (dB) can be monitored in real time. The microphone sensitivity is adjustable via the calibration menu.
App with no ads, banner or popups.
Features as sound meter (decibel meter):
A, C and Z (flat) frequency weightings,
Fast and Slow time weightings,
Equivalent A-weighted continuous sound stage (LAeq),
A-weighted sound exposure degree (LAE or SEL),
A-weighted sound exposure degree for a nominal 8-hour working day (noise dosimeter: LEP,d or LEX,8h).
Features as 1/n octave spectrum analyzer:
1/3 octave band spectra: Centre frequencies 25 Hz to 16 kHz,
1/1 octave band spectra: Centre frequencies 31.5 Hz to 8 kHz,
A, C and Z (flat) frequency weightings,
Fast, Slow and Impulse time weightings,
Equivalent continuous sound level (Leq).
If you aren't conversant in Sound Pressure Level (SPL) indicators, use the default choice: LAF and LAeq indicators respectively for instantaneous and averaged noise measurements.
Warning: This App does not declare to be an alternative to an approved Sound Level Meter. The accuracy of the measurements relies upon carefully on the specifications of the microphone/amplifier which aren't designed in a smartphone for Sound Pressure Level (SPL) measurements. This App is for indication only or for academic objective. Use an permitted Sound Level Meter the place it's required.
