About Sound Meter HQ
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
90 dB – Power tools
100 dB – Motorcycle
110 dB – Rock concert
120 dB – Chain saw
130 dB – Jet takeoff (100 m. away)
140 dB – Shotgun
Program calibration:
If you have an access to professional sound pressure level (SPL) measurements device you can use it for calibrating the application. Check current dB reading on scientific measurement device and with the help of calibration menu (calibration icon under MAX value) set the same value using +,- buttons.
Features of application:
- dB level presented on the gauge and in the descriptive way
- quick reaction on sound level change
- possibility of calibration the result according to professional device.
- minimum and maximum measurements levels.

Works great on my S7! I'm also reading reviews and I have to laugh. Right on the app it says this isn't a professional device it uses a cell phone microphone that most phones will only pick up 90 to 100db's. So if your system in your car hits 138.9 and the mic in your phone is limited to around 100db's then guess what? Your not going to get a 138.9. There's nothing wrong with the app there's something wrong with you! Read instructions before you give something a 1 star review. By the way if you spend more than $20 on a POS old model cell phone the app might just work a little better.
