I had the same experience when visiting an anechoic chamber. I think the explanation is that without external stimuli, your brain cranks up the input gain to the max, at which point you begin to hear the ambient "neural noise" from your auditory circuitry. People taking DMT or ayahuasca also often experience an extremely high-pitched sound as the drug kicks in, which also suggests a neurological basis for the phenomenon.
- detritus 5y agoI must try an anechoic chamber one day - I must! I never got the 'nee-naw nee-naws' from DMT or Ayahuasca when I did such things, but I absolutely did when going deep on Nitrous Oxide. DMT was always entirely (and oh my gosh so absolutely) visual for me.
- ddingus 5y agoAnother way to do this, that might be less stressful or painful, is to just spend a week out in nature. We go four week long Outdoor Adventures, where nothing works except for AM radio late at night. After a few days, hearing very significantly improves. On the last trip we took a Macbook, and watch the movie about 4 days in, and we're shocked at just how great that laptop sounded! It seems very loud and amazing, where in an ordinary City environment it's just normal acceptable sound. Any of you that get a chance to try this really should, it's dramatic. And it makes me really appreciate the audio engineering that went into those devices. A lot of that engineering won't ever be heard by people for in urban environments, but it is there, the work was done, and the results are pretty fantastic.
