How to listen to the calculated sound (sound synthesis of electrical machines)?

MANATEE electromagnetic and vibroacoustic software allows you to synthesize the sound produced by an electrical machine at fixed speed or variable speed (source of electromagnetically-excited noise only, but an additional noise source can be added).

Once the simulation is run the following command launches the sound synthesis:

>>play_noise

The quality of the variable-speed sound synthesis process can be improved using these guidelines. The variable speed sound synthesis can be carried either using the variable speed mode (Input.Simu.is_varspeed=1) or using the spectrogram synthesization technique (Input.Simu.is_spectro_synthesis=1).

An example of PWM sound at fixed speed generated with MANATEE (asynchronous switching at 4800 Hz) can be listened here:
