db meter sound test(Sonomètre)

DBメーター音試験（Sonomètre）は、空気を通過音を測定します

Sound test Decibel (dB) is also known as sound level meter, decibel counter (dBmeter), noise meter, sound pressure level counter (SPC counter)

It generates all test signals, performs an analysis and displays the results according to the user's configuration.

Tests are quickly created from a large library of predefined steps using the simple "sequence editor"

point-and-click: Text programming is not required. User-defined steps can be added to the library,

and the custom LabView code can even be integrated into a sequence to extend its capabilities.

 A sequence can be as simple as 3 steps to simply play a test signal and acquire and display the response,

 or as complex.

 This Sound tester is a speaker test includes a real-time virtual analyzer, a multimeter, a signal generator, a spectrum analyzer and an oscilloscope.

Although it is an extremely powerful and flexible product, its capabilities can be described in 3 parts:

Test sequences - how the tests are configured by the operator

Virtual Instruments - Software Implementation of Standard Audio Test Equipment

Data analysis - the different analyzes that SoundCheck can perform on your data

The Sound Meter (or SPL) application displays decibel values ​​by measuring environmental noise, displaying measured dB values ​​in various forms. .

This application will use the phone's microphone to measure environmental noise decibel (dB) and display a value for reference.

With this application, you can easily measure the current level of environmental noise. Simple and easy to operate.

1. Indicates the decibelle per gauge

2. Display the current noise reference

3. Display of minimum / minimum decibels

4. Can calibrate the decibel for each device

The microphones of most devices are aligned with the human voice and the maximum values ​​are limited by the hardware. Very noisy sounds
