It is the friction of electrons that cause the sound. More current flow then more sound.

Whille f***ing also some sound is produced

SCRs don't make sound, but the SCR drive and power supply electronics will if they are switch mode and/or running a pulse modulated signal. Other examples are computer switchmode power supplies, variable frequency drives and old light dimmer switches.

You may or may not be able to hear them depending on switching frequency, resonance, background noise, hearing sensitivity, etc.
