Decibels: Sound Level dB Meter

Do you want to measure sound level? This is a smart sound level meter app for iPhone!
Our decibel meter uses your built-in microphone to measure sound volume in decibels (dB) and also displays samples on graph.
Sound Meter work efficiently to find the level of environmental noise including acoustic. Sound Detector is known as SPL Meter or Decibel Meter (dB Meter). Through Sound Detector or Noise Detector you can easily detect too much loud or too much low sound in order to prevent your hearing functionality.

dB Meter is a full of features dBA sound level meter (noise meter) with exclusive accuracy of sound frequency measurements calibrated with a professional decibel meter.
Sound meter is an indispensable tool for your daily life, no matter what you do, where you stay, it is a practical noise detector to help you avoid noise pollution that harms your hearing and affect your rest. Our sound meter app can provide accurate decibel data and show you how the decibel goes.

Microphones in IOS 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). Decibels: Sound Level dB Meter 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 App Store. We have adjusted Decibels: Sound Level dB Meter with the use of professional sound meter used by sound engineers and made required adjustments for many IOS devices, including the most popular devices on the market today.

Features:
- Indicates decibel by gauge
- Display the current noise reference
- Display min/avg/max decibel values
- Display Elapsed time of decibel
- Show the reference value for each type of environment as the sound level we are measuring.
- Save data & View history.
- Can calibrate the decibel for each devices
