Sound measurement with DASYLab
Sound power measurement with DASYLab
In this short presentation I will show you how to install and use the sound level and sound power module for DASYLab.
The sensitivity values of the measurement microphones can be determined directly in DASYlab using a microphone calibrator.
The sound level values at the output of the sound level module can be connected to the inputs of the sound power module.
After entering the correction values for the measuring chamber, you will receive the sound power value at the output in this example Lw(A).

With these DASYLab Add-On modules you may determine sound power levels easy and according to standards. These modules share the following tasks:
The SLM module (Sound Level Measurement) determines a sound pressure level in dB from a time signal (should be a microphone signal in most cases).
The SPM module (Sound Power Measurement) determines the sound power from some sound pressure levels regarding all correction terms necessary.
Inputs
The SLM-module has 1 to 16 inputs, which may be switched on and off by the ‚+‘ – and ‚-‘ – buttons.
The Inputs expect time signals coming from microphone inputs having a scan rate of some kHz. If the Scan rate is too low, the time weightings and frequency weightings cannot be calculated exactly.
With scan rates below 100 Hz a warning message is displayed, because correct time weightings cannot be calculated exactly.
With scan rates below 30 kHz a warning message is displayed, because correct time frequency cannot be calculated exactly.
Outputs
The SLM-module has one output for each input. With at output rate of approximately 20 ms the level in dB of the appertaining input signal is calculated.
