Is there such a thing. In my house at night, I hear a hum, similar in frequency to an AC compressor or refrigerator hum, even sort of changes intensity. But I cannot locate any possible source for the noise. Was wondering if it's me.
Anyone know if this happens, or is it always the high test tone type noise?
