"Pulse" is extremely vague. A pulse of what? Electric shock?

  Yes, they are trying to be euphemistic. These are dog collars made for cows.

  Yes, the sound of a pulse of electricity similar to the fence they're already familiar with. Cows are typically kept in pens with high-voltage electric fencing. The energizer fires a 3,000V pulse, lasting about 300 microseconds, every second or two. This 1Hz impulse is often audible as a repetitive hum if you stand near the wire. By replicating the sound I expect you could suggest the cattle move somewhere else.

    my cows are too smart for electric fences. i set one up to separate 2 herds with a bull in each herd. the bulls will fight if the ladies are in season. they watched me set up the fence worked out that I placed the control box up at the same time the the fence got all zappy they pulled all the wires out of the control box. Cows are a lot smarter than people give them credit for.
