Your question: "Do(es) someone know how the ear physically can close to the lower level?" A simplistic explanation is that the brain perceives an "over-load" and translates that to the muscles around the ear canal. My olde teacher calls that "Ear Fatigue". It is, indeed, a real physical phenomenon. Also, if the "over-load" is too great, the brain will create Tinitus, (ringing in the ear(s)). The actual medical explanations are much more complicated that my explanation. A person to inquire to would be Diane Hoffstetter. She will be giving a two part class, at the Pacific North West Regional, this coming March, (27, 28, 29), in Portland, Oregon. Just had to get in a commercial. <G> Hope you all have a joyous and busy Holiday Season! Joe Garrett, RPT, (Oregon) Been There, Didn't Like It, So I'm Here To Stay! [G}
