Tentang db meter sound test(Sonomètre)

Sebuah tes suara db meteran (Sonomètre) mengukur suara yang bergerak melalui udara

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.

Manual Signal Generator

Sinus

Pink and white noise with a user-defined frequency range

Wav file with RMS and Peak level calibration

Equalization using calibration measurements or any user-defined curves

Optional USB button available for frequency signal generator and level control

Multimeter

Average, maximum, minimum (RMS and Peak) with overload indication

Linear and exponential calculation time (fast, slow and user-defined)

A, B, C and user-defined weights Selectable Max / Min values ​​with Pass / Fail indication

Real Time Analyzer

octave filters with true recursive digital filters

Average, Maximum, Minimum level with overload and real-time indicators

A, B and C and user-defined weighting filters

Complies with ANSI S1.11 and IEC 1260 linear and exponential standards (fast, slow and user-defined)

Oscilloscope

release

Delta Slider

Selectable graphic zoom

View the spectrum of the current waveform

Spectrum analyzer

FFT with arbitrary number of spectral lines (limited only by the speed and memory of the computer)

Hanman, Hamming, Blackman-Harris, Blackman, Blackman, Flat top, 4 Term Blackman-Harris and 7 Term Blackman-Harris

release

Complex or power average

Average, Maximum, Minimum level with overload and real-time indicators

Average calculation time (linear and exponential)

A, B, C and user-defined weights

Pure tonne frequency and amplitude extraction

Delta and Harmonic slider with THD playback

Selectable graphic zoom

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
