I've been able to tell whether a TV or similar appliance is on or not by hearing a faint, high-pitched whine or hum.
I can hear a TV on standy. Have always been able to regardless of who's house I am in. We just have good, dog like hearing.

) it's just pitch perfect silence but if I'm in a house or built up area and I focus my ears I can hear background whine, like a muted TV noise but sort of /everywhere/.
