Abstract
<b>Introduction:</b> The exposure to unsafe sound levels is considered a risk factor for developing noise-induced hearing loss (NIHL). Personal listening devices (PLDs) represent a common source of recreational noise among young adults. First changes of NIHL could be detected at extended high frequencies (EHFs).<b>Aim:</b> This pilot study aimed to analyze hearing thresholds at conventional frequencies (CFs) and EHFs in young adults due to the PLD use.<b>Methods:</b> Hearing thresholds of 114 otologically normal adults aged 18 to 30 years unexposed to occupational noise were assessed using conventional and extended high-frequency audiometry. Data on PLD use, leisure time noise exposure, health and lifestyle, were acquired using a questionnaire.<b>Results:</b> Differences in hearing thresholds were found at CFs but not at EHFs according to the listening frequency (daily vs less frequent listening); duration of one PLD use of more than 30 minutes; and total listening time ≥7 hours/week. Only the highest frequency was affected by loud volume listening.<b>Conclusions:</b> Changes in hearing thresholds were found at CFs, whereby long duration, high volume and daily use were associated with lower hearing thresholds in otologically healthy adults.
