About this app

Application "Sound Meter HQ Pro" uses built-in microphone to calculate sound level (noise level) of surrounding. Result of the measurements is displayed in decibels on the screen of you phone.

DISCLAIMER:
Don't treat this utility app as a professional device to measure decibels. This tool uses built-in microphone, which was designed to capture human's voice. Such microphone is not able to capture sounds above ~90 - 100 dB (Maximum value differs depending on kind of microphone you have). In addition, some devices are equipped with AGC (Automatic Gain Control). This system can also disturb correct sound pressure level measurement.

Measured noise level is presented with the help of indicator on the gauge. Loudness level varies between 0 and 140 dB. Besides live noise measurement the application displays also minimum and maximum registered level of the sound. You can clear it any time by using "Reset" button.

Moreover our tool displays noise power in descriptive way. Available descriptive sound measure 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 (100m away)
140 dB – Shotgun

Decibel meter calibration:
If you have access or you possess professional sound pressure level measurements device (SPL meter) you can use it to calibrate our app. Firstly, check current decibel reading on scientific measurement device. Next open our calibration menu (calibration icon under MAX value) i our app and set the same value using +,- buttons.

Features of application:
🔈 quick reaction to sound level change
🔉 decibel level presented on the gauge and in the descriptive way
🔊minimum and maximum measurements levels.
🔊possibility of calibration the result according to professional device.

Ratings and reviews

I love that this app has no ads! It would be even better if the instructions on how to calibrate were on the app. I did find them here on the PlayStore listing, however. I don't have the equipment needed to calibrate, so it doesn't matter anyways! Just glad to have something to help me preserve my hearing by avoiding excessive noise levels. Thanks!!!

No adds. Thank you The thing at the top telling you what ever day sound matches your current spl is annoying. It moves around way too much, distracting your eyes. For me even an analog style graphic is annoying. Mimum screen motion is ideal, all I want is the number. I have not done any tests to check the accuracy of the reading. I was bullied into writing this review by the app notifications which happened like 4 times while having the app for 20 mins This is way better than having ads thanks

Pretty decent sound level meter. I adjusted it a bit, to bring it to agreement with my pro-level meter...but it was fairly accurate as downloaded. I really like the fact that the app doesn't require a bunch of unrelated permissions. It doesn't have a lot of fancy features, but then again - why would it need them? It is simple and effective. Well done.
