Age-related hearing loss (ARHL or presbyacusis) is an increasingly common form of sensorineural hearing loss (SNHL) as a result of changing demographics, and the auditory brainstem response (ABR) is a common experimental and clinical tool in audiology and neurology. Some of the changes that occur in the aging auditory system may significantly influence the interpretation of the ABR in compariso...

The aim of this study was to highlight the clinical characteristics of tinnitus and to attempt a quantitative assessment in relation to any underlying etiologies. We undertook to study a population of 123 patients attending a tinnitus clinic between 1998 and 2000. Their answers on a questionnaire allowed detailed evaluation of the characteristics of tinnitus, including such variables as the cir...

Hearing thresholds in elderly humans without a history of noise exposure commonly show a profile of a flat loss at low frequencies coupled with a loss that increases with frequency above approximately 2 kHz. This profile and the relatively robust distortion product otoacoustic emissions that are found in elderly subjects challenge the common belief that age-related hearing loss (presbyacusis) i...

A review of large-scale surveys of hearing over the past 50 years reveals a "gender-reversal" phenomenon in the average audiograms of the elderly. Above 1 kHz males show greater average loss than females, but below 1 kHz females show greater average loss than males. The effect increases with both age and degree of hearing loss. The difference is present whether or not the elderly persons compla...

The purpose of the study was to determine the effect of tinnitus and total effect of tinnitus and the hearing loss function on the distortion product otoacoustic emission. Tinnitus patients were selected to exhibit normal hearing and such tinnitus patients who exhibited the increasing or notch-like sensorineural hearing loss. It was found that the cochlear hearing activity expressed in terms of...

Age-related hearing loss (ARHL) or presbyacusis is a progressive loss of hearing sensitivity that is predominately associated with sensory or transduction neuro-cell degeneration in the peripheral and central auditory systems. Increased production of reactive oxygen species (ROS) and inflammatory response were frequently found in aging cochleae. In addition, inflammasomes are likely responsible...

The average asymmetry between the hearing threshold levels in the left and right ears was analyzed in a random population (n = 3487) representing a normal population. Males and females of age groups 5-10 years, 15-50 years and over 50 years were analyzed separately. A significant average inferiority of the hearing in the left ear was found at high frequencies, especially at 3-6 kHz, among adult...
