This project is for matlab development of a virtual sound level meter. The program will read in a .wav file and allow the user to analyze it as one would analyze a sound field with a sound level meter..

This tutorial/demo presents the design of a sound level meter in Matlab. The Data Acquisition Toolbox is used to implement a real-time spectrum analyzer. The decibel meter is implemented in the frequency domain using Parseval's relation. Documentation is provided in the included PDF. Further information is available at: http://mesh.brown.edu/dlanman..

Sound Level Meter is in the 4th set of the Smart Tools collection (noise).

SPL(sound pressure level) meter app uses your phone mic to measure noise volume in decibels(db), and shows a reference.

REMEMBER!! The smart phone microphones were aligned to human voice (300-3400Hz, 40-60dB). Therefore the maximum values are LIMITED by the manufacturers and the very loud sound(100+ db) cannot be recognized. Moto Droid(max.100), Galaxy S3(81dB), Galaxy Note(91dB), Galaxy S2(98dB)...

Best Sound Meter (sound pressure level) is an app which can measure the actual sound level meter with dB.
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.

Sound Meter for Android allows you to measure environmental noise with your mobile phone.

SPL(Sound Pressure Level) meter uses your phones microphone to measure noise volume in decibels(db)and shows a graph for you to visualize the measurement.

Note that mobile phone microphones were aligned to human voice at 300-3400Hz (40-60dB).

The maximum values are LIMITED by phone manufacturers, so very loud sound at 110+ dB may not be very accurate.

***How to use***

The app automatically displays the SPL measurement when you start it, the graph shows you the maximum and minimum values within 8 seconds.
