Extended high-frequency audiometry in research and clinical practice
The sensitivity of young healthy ears extends up to 20 kHz, and recent research indicates that testing in the Extended High-Frequency (EHF) region, above 8 kHz, could provide valuable additional information.
Basal cochlear regions that operate in the EHF range are particularly sensitive to the effects of aging, disease, ototoxic drugs, and possibly noise exposure. Consequently, EHF loss could serve as an early indicator of damage, aiding in diagnosis and monitoring of hearing health.
Moreover, EHF loss has an impact on sound localization and may also directly affect speech perception in noisy environments.
The Inventis audiometers, Cello and Piano Plus, are the ideal solutions for High-Frequency audiometry! They enable the determination of the hearing threshold within the frequency range of 8 kHz to 20 kHz, in air conduction using the supplied high-frequency headphones, or in free field.
