Most studies of hearing are based on Europeans or Asians or their descendants, in, e.g., N. America. There is little data on other human populations. The San people of southern Africa represent one of the oldest distinct human populations, being almost completely separate from all other groups for > 100k years. We report a study in young adults belonging to the Ju/’huansi of the Nyae Nyae San...

Distortion-product otoacoustic emission (DPOAE) level maps measured across audiological frequencies differ. Keefe JASA 111:249–260 (2002) suggested that if the distortion characteristics of the basilar membrane (BM) are uniform along a large part of its length, the differences in DPOAE level maps across frequencies from 0.5 kHz to 8 kHz should reflect the forward and reverse transmission of...

It is well established that middle ear transmission is influenced by posture. This phenomenon is associated with variations in intracranial pressure (ICP) when a subject transitions from an upright to a supine position. Typically, this transition leads to an increase in ICP. The resulting rise in endocranial fluid pressure alters middle ear (ME) impedance, generally producing an increase in...

The ability to understand speech in adverse listening conditions, such as in the presence of masking noise, is severely degraded in people with hearing loss. The mechanisms that underly these speech deficits are still not fully understood. A healthy auditory efferent system has been argued to facilitate understanding speech in noise. Evidence from computational auditory models that include the...

Researchers and clinicians measured the gross action potentials from the round window or the scalp to investigate the physiological state of the auditory nerve. However, the generators underlying these responses are not fully understood. By combining intraoperative auditory nerve recordings with computational modeling, we show that the unitary action potential recorded directly on the nerve is...

Amplitude- and latency-growth functions of auditory evoked potentials are classical measures of peripheral auditory function, yet existing datasets suffer from insufficient age control, small sample sizes, and insufficiently detailed stimulus calibration — all of which limit their precision for validating computational models. This study provides a rigorously controlled reference dataset by...

Frequency-following responses (FFR) may be sensitive to auditory nerve degeneration and auditory processing deficits beyond what is captured by the clinical audiogram. The clinical potential of this measure relies on robust, quick and reliable acquisition in the clinic. Multiway canonical component analysis (MCCA) presents a way of utilizing common response patterns across multiple channels...
