I get this weird phenomenon you're describing to an extent - phantom sounds, like bass or low frequencies. I have used a bedside white noise machine turned to brown noise to block low frequency rumbling of loud trucks and bass music but it has this terrifying effect of making me think I hear low frequencies that aren't actually there. It's maddening.
