Abstract
Hearing sensitivity changes throughout a person’s lifetime. This work aimed to describe changes in pure-tone audiometric (PTA) thresholds that occur in the transition from young adulthood to middle age in 121 adults with normal or nearly normal hearing. Results showed that older people had worse high-frequency (4000-8000 Hz) thresholds but unexpectedly better low-frequency (125-500 Hz) thresholds than younger individuals, suggesting that hearing sensitivity in the low-frequency range may improve with age. The improvement of low-frequency thresholds may be part of a central compensation for age-related deterioration of high-frequency hearing sensitivity. Further studies of age-related changes in low-frequency hearing sensitivity are needed to confirm our findings.

The file contains information about the pure-tone audiometric (PTA) thresholds of 121 adults. Thresholds were obtained using a calibrated clinical audiometer (Affinity 2.0, Interacoustics, Denmark) with a circumaural headset and measured in dB HL (hearing level). Each participant’s thresholds were averaged between the ears for each tested frequency.
The file contains the following fields:
- A unique participant ID (Participant_ID)
- Participant sex (Sex)
- Participant age (Age)
- Frequencies at which thresholds were measured: F125_Hz, F250_Hz, F500_Hz, F1000_Hz, F2000_Hz, F2000_Hz, F4000_Hz, F8000_Hz
Methods
Pure-tone audiometric (PTA) thresholds were collected from 121 participants aged between 18 and 47 years. The thresholds were obtained at octave frequencies between 125 and 8000 Hz.
