REMEMBER!! The built-in microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore the maximum values are LIMITED by the hardware limitation, and very loud sound(100+ db) cannot be recognized. Moto Droid (max.100), Galaxy S3 (81dB), Galaxy Note (91dB), Galaxy S2 (98dB)...
SPL(sound pressure level) meter app uses your built-in microphone to measure noise volume in decibels(db), and shows a reference. We had calibrated many android devices with the actual sound level meter with dB(A).
See the 4-6th pictures. I had calibrated many android devices with an actual sound level meter. You can trust the result in routine-noise levels (40-70dB). But, please use it as an auxiliary tool.
* Pro version added Features :

** Not compatible with: Xperia(X8, X10 mini), LG(Optimus One, P350), GT-I9001, ZTE, etc
Microphones in Android devices are made to record human voice, therefore the maximum noise is limited and very loud sounds cannot be recognized (in most cases above 100dB). Sound Meter PRO is calibrated to be accurate in +-2.5 dB range of actual noise level and is probably by far the most accurate sound meter on Google play. We have adjusted Sound Meter PRO with the use of professional sound meter used by sound engineers and made required adjustments for many Android devices, including the most popular devices on the market today.
Levels of Noise In decibels (dB) according to American Academy of Audiology (www.audiology.org):
140 dB - Gun shots, fireworks
130 dB - Jackhammers, Ambulance
120 dB - Jet planes taking off
110 dB - Concerts, Car horns
100 dB - Snowmobiles
90 dB - Power tools
80 dB - Alarm clocks
70 dB - Traffic, vacuums
60 dB - Normal conversation
50 dB - Moderate rainfall
40 dB - Quiet library
30 dB - Whisper
20 dB - Leaves rusting
10 dB – Breathing
Why would you use Sound Meter PRO? Measure the noise your neighbors make, check new computers, refrigerators, air conditioning units before your buy them for noise levels and select the more quiet ones, to have less noise pollution in your home. Measure how loud your car, motorcycle is. Adjust the sound system for the party you are making to safe levels not to damage peoples hearing. Measure the noise in the apartment, house you are about to buy, it might be too noisy to live in and demand for extra noise insulation. Measure your love ones snoring levels and show them the graph after. Possibilities are endless, Sound Meter PRO is a must have app for every Android device.
This decibels of volume or decibel meter (dB meter), the noise meter, sound level meter (SPL meter).
The noise of their surroundings is the sound level meter to measure how much.
This shows that the referenced using your built-in microphone.
You can measure the number of Android devices in dB and the actual sound level meter.

Noise Sound Light level meter
dB Lux counter
It uses your built-in microphone and shows a reference. We had calibrated many android devices with the actual sound level meter with dB.
You have to know that the built-in microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore the maximum values are limited by the hardware limitation, and very loud sound (100+ db) cannot be recognized.
Remember that it's only a device for fun and please use it as an auxiliary tool.
- Display the Average, Peak and Max values with both nice and clear digital and analog layout
- Quick reference text to help you compare with real-life examples
- Plotted history of the Average values
- Record and export the data to email for further analysis
- Tap on Max value to reset it any time
- Adjustable sample rate, ranging from 4Hz to 20Hz
- Calibrate the measurements from -10dB to 10dB
- Enable/disable auto-lock screen
- Start or stop the tool at any time
- Beautiful, clean and intuitive design
- The built-in microphone is only sensitive from 0 to approximately 100 decibels
- Some devices do not have built-in microphone so in order to use the app, it is required to plug in an external microphone
- Even though we have tried our best to make the app as accurate as possible, this app is intended for entertainment purposes only
-- SPECIAL NOTE --

Sound Meter is handy tool - you may find amazing how loud your dog barks or your washing machine works!
Sound Meter features:
- Measuring sound level in decibels

- Graph shows the noise level for the past 30 sec
- Calibration possibility
- Screenshot of sound level graph
If you are searching for sound level meter, decibel meter, noise meter, sound pressure meter, dB meter or SPL meter then Sound Meter is the app you need.
Sound Meter uses microphone of your device to measure level of noise in decibels. Different device models have different microphone sensitivity, so you might need to calibrate Sound Meter a little. You can do it by going to Settings -> Calibrate and selecting appropriate sound delta value. Also, most microphones used in mobile devices are designed to work in the human speech sound range, therefore it might be vaguely sensitive to very high or very low noise levels and the app may not display them.
Sound Meter can be useful for various occasions. For example if you are looking for a flat and would like to chose a quiet one, you can measure sound level with this Sound Meter and then compare results and chose the quietest flat. It is vey easy to make screenshots of sound graph with Sound Meter so you can compare sound levels for various locations.
If you like this Sound Meter you can also try Sound Meter Pro app. Which does not contain ads.
Please, don’t downvote this Sound Meter if you don’t like something, or have any questions. Instead just mail us to email@example.com and we will try to help you with everything!

REMEMBER !! The micro phone was calibrated on the human voice (300-3400Hz, 40-60dB), the maximum value is Limited. The loud noise (100 + db) can not be recognized: Moto Droid (max.100) Galaxy S (81dB) Galaxy S2 (98dB) ...
Sound Level Meter uses your phone mic to measure the ambient noise in decibels.
See photos 4 and 5. Many devices were calibrated by a real indicator of the level meter level dB (A).
Measured value, maximum value, indicates the minimum value.
Smartphones microphone to measure the sound pressure level.
Smart phone microphone is optimized for voice bandwidth (40 ~ 60dB).
Other than voice bandwidth can have measurement errors.
Depending on the capabilities of the smartphone can be a measurement error.
If you want a detailed measurements over a wide bandwidth, it is better to buy a professional Sound Meter.
It uses a Fast Fourier Transform algorithm to implement a high precision A weighting filter and sophisticated digital signal processing techniques to achieve the best possible SPL readings out of your Android phone or tablet.
It displays the current, maximum and minimum values in decibels, and generates 3 kinds of sound pressure level versus time charts. The display can be turned upside down to allow pointing the mic at the sound source.
deciBel is supported by ads.

1. Due to microphone limitations on different devices the meter range is different, usually the low end of the scale cannot be achieved because of the microphone noise and the upper end of the scale is limited by the microphone distortion on high levels.
2. Devices employing AGC (Automatic Gain Control) that cannot be automatically disabled by this app will have significant measurement errors and limited range. This is not app's fault.
3. If you have measuring problems or doesn't work at all, try to disable "Use high sampling rate" in settings, restart the device and recalibrate.
