Do electric fences make any noise?

Answer 1

Yes, even when operating properly, electric fences can generate noise.

Two types are common: clicking and radio noise. Clicking is part of normal fence operation when a charger releases energy that travels along the fence.

Although it does not affect fence operation, radio noise is not normal and must be fixed according to the Federal Communications Commission rules as the sounds can disrupt radios and television reception, telephones, and other communications devices.

Almost all radio noise generated by electric fences is caused by a spark or arcing of the electrical current across fence hardware.

This type of interference produces a characteristic tick-tick-tick sound that can disrupt communications at distances of up to a mile.

Typical sources of arcing include bad splices in fence wire and gate hooks. Fence wire acts as an antenna to broadcast the arc.

While some electric fence systems have audible alarms or warning devices to indicate when the fence is active or when there is a fault in the system, electric fences themselves do not produce sound.

Electric fences themselves do not make noise. However, some electric fence systems may include components such as energizers or controllers, which can produce a clicking or humming sound when they are operating.
