Extended high frequencies (EHF), above 8 kHz, represent a region of the human hearing
spectrum that is generally ignored by clinicians and researchers alike. This article is a …

While human vocalizations generate acoustical energy at frequencies up to (and beyond) 20
kHz, the energy at frequencies above about 5 kHz has traditionally been neglected in …

Objective: The aim of the present study was to study patterns in the extended spectrum of the
human hearing (0.125 to 20 kHz) in order to obtain reference thresholds. Then, we compare …

Mammals localize sounds using information from their two ears. Localization in real-world
conditions is challenging, as echoes provide erroneous information and noises mask parts …

Monaural spectral features are important for human sound-source localization in sagittal
planes, including front-back discrimination and elevation perception. These directional …

Anecdotally, middle-aged listeners report difficulty conversing in social settings, even when
they have normal audiometric thresholds [1–3]. Moreover, young adult listeners with" …

A fundamental principle of neuroscience is that each species' and individual's sensory
systems are tailored to meet the demands placed upon them by their environments and …

At frequencies above 3 kHz, the tympanic membrane vibrates chaotically. By having many
resonances, the eardrum can transmit the broadest possible bandwidth of sound with …

Objectives: The hypothesis that extending the audible frequency bandwidth beyond the
range currently implemented in most hearing aids can improve speech understanding was …

Audiometric testing in research and in clinical settings rarely considers frequencies above 8
kHz. However, the sensitivity of young healthy ears extends to 20 kHz, and there is …
