A surge protector is an appliance designed to protect electrical devices from voltage spikes. A surge protector attempts to limit the voltage supplied to an electric device by either blocking or by shorting to ground any unwanted voltages above a safe threshold. The surge energy rating is a measure of how much energy a surge protector can theoretically absorb in a single event, without failure.

The amplitude level of the undesired background noise, usually measured in decibels (db).
