Every smart phone, there may be an error of the measured value.
The noise of their surroundings, you can measure how much.
Android 80 ~ 100db of sound to the maximum value of the equipment may vary.
You're starting to sound measurement can check the maximum and minimum values.
Noise measurements require precise high-performance, we recommend using the sound level meter.

Features 1/1, 1/3 & 1/6 octave RTA modes, Leq (wideband, Octave, variable duration), RT60 (wideband, Octave), Spectrogram, Peak frequency, Fast, Medium & Slow filters, Flat & A/C Weighting and film industry X Curve, Averaging, SPL Chart Recorder, Noise Criteria, White/Pink Noise, Sine, Square, Triangle, Sweep, Ramp and Impulse signals & loudspeaker polarity checker, L/R select. RTA Store & Load, Hann windows, "Keep Screen On", pinch to zoom, scroll to center.
Exclusive ISO 1/3 Octave Calibration - correct for your phone's microphone response. Octave calibration discs are moved up or down to obtain a flat response, and match the overall SPL to that of an external meter. Save/Restore of Cal files (Dayton Audio iMM-6 also supported).

AudioTool FFTs sets of samples recorded at the microphone. Aliasing reduced by Hann windowing. SPL calculated in realtime. Spectra may be saved as files on the SD card, then loaded and displayed with the live spectrum. The "Store" button stores the current live spectrum - "Load" shows a list of stored spectra to select.
To hide the buttons, tap the screen. To restore them, tap again. To zoom the scale, pinch the screen. To move the scale, drag it up or down (left or right).
The deciBel meter uses IIR filters and exponential averaging to calculate Flat, A and C weighted response at speeds of Fast, Medium and Slow speeds.
A pair of cursors can be shown on the RTA and Chart Recorder displays: each can be moved to any position, and will display the SPL & time/frequency values there. Initially, both cursors are positioned mid-screen - simply drag them to a new position with the fingertip. The cursors can be turned on and off in the Menu.
The loudspeaker polarity checker can be used to check whether a loudspeaker is wired in phase: connect the AudioTool output to the speaker under test, select "Polarity" from the signal generator screen, then return to the RTA screen. If the speaker is out of phase (polarity reversed) AudioTool will show "Pol ---", otherwise "Pol +++" if the speaker is in phase.
The Noise Criteria (available from the Menu) function shows a set of NC contours overlaid on the 1/1 Octave RTA display and the calculated real time current NC value is also shown.
The Chart Recorder shows a moving trace of the SPL measurements over the last few minutes.
RT60 measurements can be made by starting the RT60 component using the "RT60" button, and then using a loud clap (or similar) to trigger the measurement. RT60 can also be used with Pink Noise from the AudioTool generator. RT60 times measure how much reverberation or echo there is in a room or auditorium.
The Signal Generator generates White and Pink Noise, Sine, Square, Triangle and Ramp waves, Sine Wave Sweeps and Impulses. The generator uses multiple cycled buffers, refreshed randomly so ensuring truly random White/Pink noise. Pink Noise algorithm uses Kemmet's method to adjust White into Pink.
The frequency accuracy of the generated periodic signals is typically around 1%. Sine wave fidelity is good throughout most of the audio range. Other signals' leading and trailing edges show ringing and decreasing frequency response artifacts in the upper ranges, depending on the Android used.

Harmonicity is a measure of the sound energy in the harmonics relative to the rest of the spectrum.
Harmocity varies with age, gender & which vowel you pronounce. Higher harmonicity values indicate a purer sound. Whilst lower jitter and shimmer values indicate a purer sound.
This meter is supposed to be used with a continuous consistent sound, e.g. Pronoucing a vowel, or a tone from a speaker/instrument. Rapidly changing tone/sound will give nonsensical output.
FOR INDICATION ONLY. Harmonicity will vary depending on how close the source is to the microphone. Microphone sensitivity varies with frequency and from device to device. Even amoungst scientific literature, it is difficult to find consistency in absolute reported values.
Jitter is a measure of the frequency variation of the sound. The relative jitter is shown as a %.
Shimmer is a measure of the amplitude variation of the sound. The relative shimmer is shown as a %.
Autodetects sound – App will only start measuring when a sound is detected.
Averaging - After 0.7s, the app will start averaging the Harmonicity, Jitter, Shimmer and freqency values. This will continue until the sound is stopped at which point the last 0.7s of data is removed from the averaged values.
Musical Note – The current detected frequency is converted into a note based on western 12 tone equal temperament. Use to tune your guitar or other instrument if you wish.
Pause button – Useful if in a noisy environment and measurement doesn't auto stop.
FFT Spectrum – Autoscaling Sound Intensity between 0 and 2 kHz.
Range: 100 Hz to 2 kHz fundamental harmonic frequency detection.
Internet Permission is for link to website with more info/user guide for app.
The fast fourier transform (size 8192) is performed on the last 0.74s of data to produce a frequency spectrum (0 to 5.5 kHz with 1.35Hz resolution). This frequency spectrum is windowed between 100 and 4 kHz with linear fall offs to zero at 50 and 5 kHz. The fundamental frequency is determined from polynomial fitting to peaks. The harmonic energy is determined from the sum of the FFT signal at the harmonic freuquency plus 8 Hz either side. The noise is the sum of the rest of the FFT. The ratio of harmonic to noise energy is the Harmoicity and is displayed in decibels.
