Decibel Measurement for Noise. Sound Meter Test.

Decibel (dB) Meter in your pocket. DB Sound Metter is feature rich sound meter app, ultra-precise noise meter & environmental noise detector app. The sound level meter (SLP) will show decibels of noise level of any room or environment you want to measure: traffic, stadium noise, concert, at your home, noise from outside etc.

Sound level meter with exclusive accuracy of measurements. Calibrated with professional high-precision decibel meter. This app will use the phone microphone to measure environmental noise decibels (dB) and show a value for reference. Sound meter is also known as sound level meter, decibel meter (dB meter), noise meter, sound pressure level meter (spl meter).

We have made this dB Meter for that you could save on purchasing of professional sound level meters which cost hundreds of dollars. At the same time we love beautiful design and we like to surprise, therefore, having acquired our dB Meter you also receive the graceful and extremely convenient app with intuitive interface. "decibel meter app (db meter) is best sound level meter app for Android. This app can uses your built-in microphone to measure sound decibels and show displays line chart on screen.

Please note that dB Meter - Decibel Measurement Tool app is not a replacement for a professional device and should be used for private purposes only. It provides a simple way to measure audio volumes in your environment. The app shows the approximate dB (decibel) level, also known as Sound Pressure Level (SPL).

Sound level meter(or SPL) app is shows a decibel values by measure the environmental noise, displays measured dB values in various forms. You can experience tidy graphic design with high frame by this smart sound meter app. Levels of Noise In decibels (dB) according to American Academy of audiology, From 0 dB to 150 dB between the division, for example: 60 dB is "Normal conversation ".

Features:
- Unique and attractive design.
- Exclusive simplicity and convenience of use.
- Highly accurate measurements.
- Lux quality.

The high decibel value will be harmful to your physical and mental health and hearing function. You'd better avoid exposure in noisy environments. SPL(sound pressure level) meter app uses your embedded microphone to measure noise volume in decibels(db), and shows a reference. 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).

DB Chart
150-160 dB = Eardrum rupture

140 decibel = Aircraft carrier deck.

130 dB = Jet take-off (100 meters), gun blast at close range.

120 dB= Human pain threshold, loud rock concert.

110 decibel = Serious hearing damage if sustained for more than 1 hour.

100 dB = Serious hearing damage if sustained for more than 8 hours.

90 decibel = Likely hearing damage if sustained for more than 8 hours.

80 decibel = Potential but unlikely hearing damage if sustained for more than 8 hours.

70 dB = Just annoying, but probably safe.

60 dB= Typical conversational volume.

50 dB = A quiet, library conversation.

40 decibel = A whisper.

30 dB= Barely audible sound.

20 decibel= Threshold of human hearing.

This tool doesn’t fully replace the sound level meter device. It gives good enough and precise measurement.

It has highly reliable, pre-calibrated measurements and supports dBA, dBC. It turns your Android device into a professional sound level meter, precisely measures the sound pressure level (SPL) all around you. DB Sound Meter is a comprehensive sound level meter app that will display max and minimum db levels so you can view and know how much actually the sound noise is compared to the gauge.

Program calibration:
If you have an access to professional sound pressure level (SPL) measurements device you can use it for calibrating the application.
