Audiology & Presbycusis Info

Natural High-Frequency Roll-off: Age-related hearing loss (Presbycusis) naturally degrades stereocilia hair cells in the basal turn of the cochlea, which respond to frequencies above 12kHz.

Testing Equipment Note: Ensure your headphones or phone speakers support flat high-frequency extension without hardware DAC clipping.

Medical Disclaimer: This diagnostic tool is for acoustic calibration and self-testing. Consult an ENT or Audiologist for clinical audiograms.
