Low deep hum, heard mostly at night as I'm a poor sleeper it wakes me up, been happening a number of years now, need to sleep with a fan on to cancel the noise out. My oldest son has Asperger's but says he never heard a hum, though he is hearing sensitive to vacuum cleaner, washing machine ect. My youngest daughter who is 5 is also noise sensitive she hears it too. I don't know if this is tied in with this study but I an RH negative.

it is like an uneven engine, it doesn't seem to be the AC that is an even hum for example but more like an idling car engine but it feels like coming from the walls. It is not a "sound" but …
