How can I get rid of the slight buzzing sound from my S60 smartphone?

Q. How can I get rid of the slight buzzing/hissing sound from my S60 smartphone? It's there whenever the phone's screen is lit. Is this buzz normal?

A. Yes and no! It's quite normal for PDAs and smartphones to emit a slight buzzing noise. There aren't any moving parts but the various electronic systems and oscillators do give off a little audio noise. Chief among these is usually the LCD screen.

On S60 smartphones, you can usually significantly reduce the noise by turning the display up to full brightness (in 'Settings | Display').

If anyone can shed more light on this (in terms of electronics theory), please comment below!
