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).
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)...
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 :
- Sound Meter and Vibrometer are integrated
- Statistic menu with saving log data
- CSV file exporting
- Level notification
- Line-chart duration
- More models are calibrated
- No ads
* Do you want more tools?

Professional sound level meter for your device.
It measures loudness or sound pressure (SPL) in decibels.
■ direct reading in dB
■ 0 to 100dB+ (decibels) range
■ fast meter response
■ max/min values display
■ selectable falloff speed
■ 5% max error (device dependent)
■ A and C weighting method
■ predefined and custom calibration
■ vibrating alert on defined value
■ source: microphone or music played
■ classic vintage analog look
■ meter rotation
■ 2 meter faces
■ 18 case skins
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) 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.
This app is able to emit high frequency sounds (ultrasonic sounds) which irritate all small insects.
Mosquitos can take that sound as the sound of their enemies (e.g. dragonflies, bats). They will keep away from the source of the sound. Just turn the repellent sound on and keep your mobile phone near you. No
mosquito bites any more!
Most of the humans can't hear sound above 17 khZ. Our app gives you the availability to set sound frequency from 9 kHz to 23 kHz! Set frequency in way that you can'thear the sound and don't worry, mosquitos will hear the sound for sure!
Remeber: Turn your volume to max while playing sound.
This app will not give 100% chance of success. There are a lot of mosquito species in the world and some of them may be resistant to ultrasonic sounds.Moreover some of built-in phone speakers are not able to produce high
That not all! We have bonus. The app is also a cool live wallpaper (one wallpaper) and widget (you can place direct link to this app on your home screen).
Environmental Noise Pollution Threatens Hearing and Health.
Measure noise with your smart phone using this app.
It is easy to use!
This is a Sound Pressure Level Meter.(SPL)
This Sound Meter calculates the Decibel level of the sound.(dB,Unit of measurement)
1. I don't guarantee that this app will work out well. And don't guarantee perfect efficiency(result,effect,effectiveness).
2. Protect your hearing(health) with exposing loud noises in a noisy environment. Do not use with Excessive Noise!
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.
