Any evidence of this? I worked in audiology for my entire 30's and tested my own hearing (biocalibration) once a week. Never once saw a reduction in my hearing thresholds (250Hz - 8kHz) Nor have I read any supporting documentation that agrees with a reduction of 8kHz thresholds before the age of 55.
