Normative Data of Extended High Frequency Audiometry in Normal Hearing Subjects with Different Aged Groups.

ABSTRACT: Background/Objectives: Conventional audiometry assesses hearing in the frequency range of 250-8000 Hz, while humans can detect sounds from 20 to 20,000 Hz. Hearing sensitivity above 8000 Hz can be assessed through "Extended high-frequency audiometry (EHFA)", which is useful for early detection and monitoring of hearing loss and counseling for tinnitus patients. Despite its usefulness, age significantly affects hearing sensitivity. Currently, there are no standard hearing thresholds in the EHF range categorized by age groups in Thailand. In this study, the aim was to determine normative EHFA data across different age groups in a healthy Thai population. Methods: This study included 134 participants aged 18-70 years, categorized into five age groups. All participants had normal
