Signal to Noise Ratio Testing
Hello All,
I am a student currently completing my final year project on a Sound Engineering Degree Course.
For this final project I have chosen to investigate the effects of wireless signal transmission in the live environment in comparison to wired transmission of signal.
To complete this project I aim to compare two Microphone systems of the same capsule, one obviously being wireless the other wired, when exposed to different forms of radio frequency interference and battery life / distance stresses. To compare the outcomes I would like to be able to assess;
Signal Strength
Signal to noise ratio
Frequency response,
Of each system under different stresses.
I would be very interested in any suggestions on how I may be able to use Electroacoustics Toolbox software to find the signal to noise ratio, as the other two tests I feel are fairly self explanatory.
Any feedback would be great as this is my first time using the software for testing rather than signal monitoring purposes.
Regards
Jon

When you measure frequency response with the Dual FFT Analyzer tool in Electroacoustics Toolbox, it will also calculate SNR (signal to noise ratio) as a function of frequency, so you'll already have that data.
If you want to measure SNR at discrete frequencies, you can use the FFT Analyzer tool. You just place a cursor at the test frequency and turn on the SNR calculation in the FFT Analyzer's info drawer.
