- crazygringo 7y agoThanks, and someone else posted [1] so now I could look for more info on it! I'm now extremely curious -- what do noise-cancelling headphones do for you? You can see here [2] that Bose's QC35's reduce the lowest frequencies (down to 20 Hz) by between 10 and 30 dB -- and the Wikipedia link suggests that the Hum is in the range of 32-80 Hz, so is certainly covered. If they make a difference, that could indicate that you truly do have a kind of extreme sensitivity there, while if they don't, it could be another (real but non-auditory) phenomenon that your ear/brain is interpreting as sound, e.g. tinnitus.

Firstly, they would need to have very good microphone sensitivity to detect the (very?) low frequencies or at least the low sound pressures of those low freqs. Also, when I tried the new big Sony noise canceling headphones (very highly rated), I found the sensation somewhat unsettling. They did indeed shut out practically every external sound (in a big store, not at home in bed), but I perceived some kind of constant subtle positive air pressure in my head similar to what you feel about half a meter under water. My solution now in the rare case where I'm in a location that bothers me is to use some low speed fan to create lower frequency white noise. Also, either I've been luckier the last few years where I've lived or I'm becoming less sensitive to it, because I don't get bothered as often.
