Application "Sound Meter HQ" calculates sound level (noise level) of surroundings with the help of built-in microphone. Result of the measurements are displayed in decibels on the screen of you phone.
IMPORTANT:
This tool is not a professional device to measure decibels. It uses built-in microphone, which was created to capture human's voice. Such a microphone isn't able to capture sounds above ~ 90-100 dB.
Maximum value differs depending on kind of microphone you have. Additionally some devices are equipped with AGC (Automatic Gain Control). This system can additionally disturb correct sound pressure level measurement.
Calculated value of noise level is displayed with the help of indicator on the gauge. Range of measurements from environment is between 0-140 dB. Besides current measurement the application displays also minimum and maximum level of the sound.
You can clear minimum and maximum measurements any time by using "Reset" button.
Additionally the application displays noise power in descriptive way. Available descriptive sound thresholds:
10 dB - Breathing
20 dB - Rustling leaves
30 dB – Whisper
40 dB – Quiet library
50 dB – Moderate rainfall
60 dB – Normal conversation
70 dB – Vacuum cleaner
80 dB – Food blender
