I get that a bit late at night, I think from the noise of the fridge compressor motor that reverberates against the wall. If I put in an earplug it stops.

- blunte 9y agoFor low frequency sounds, earplugs make it worse - they reduce higher frequency sounds much much more than they reduce the vlf sounds. The result is a more acute awareness of the annoying low freq sound. But hey, if it works for you, great!
