Is there anything that can be done to stop it?
Answer:
Probably has to do with elections.
Electronics will emit high pitch noise if they contain inductors or transformers that the voltage on them is being switched at audio frequencies. That is usually a sign of a cheap product badly designed, unless it is an old TV set (where this is done on purpose). Don%26#39;t know what you%26#39;re talking about. Whatever it is, it is certainly defective. You should return it to wherever you bought it.
