A detailed analysis of risk factors for the development of sensorineural hearing loss (SNHL) was carried out in 199 forest workers. The hearing threshold of both ears at 4000 Hz was measured, and the effect of age, exposure to noise, blood pressure, presence of vibration induced white finger (VWF), tobacco smoking, plasma LDL-cholesterol concentration, and consumption of drugs were evaluated by...

During the past three to four decades, the incidence of acquired sensorineural hearing loss (SNHL) in children living in more developed countries has fallen, as a result of improved neonatal care and the widespread implementation of immunisation programmes. The overall decrease has been accompanied by a relative increase in the proportion of inherited forms of SNHL. The contribution made by one...

However, it is important to remember that modern adaptive directional and adaptive noise reduction features are criterion based; the input signal must have certain characteristics for these systems to activate.In contrast, compression is a "24/7" function in hearing aids all signals pass through the compression system. Multi-channel, non-linear (MCNL) amplification is widely considered to be th...

A prevailing complaint among individuals with sensorineural hearing loss (SNHL) is difficulty understanding speech, particularly under adverse listening conditions. The present investigation compared the speech-recognition abilities of listeners with mild to moderate degrees of SNHL to normal-hearing individuals with simulated hearing impairments, accomplished using spectrally shaped masking no...

Background: Hearing impairment is the most common otolaryngologic manifestation of aging. Objectives: Few studies have focused on Hearing Loss (HL) in the Iranian “normal” elderly population. This study aimed to evaluate audiological problems in the normal elderly people of the rural areas of Rasht City in the north of Iran. Materials & Methods: This cross-sectional study was conducted in 2...

introduction: conductive hearing loss due to chronic otitis media (com) can be treated by surgery. com, however, may be associated with functional damage to the inner ear. sensorineural hearing loss (snhl) due to com has been found to be significant by some authors, whereas it has been considered negligible by others. the present study aimed to answer the question does com cause snhl ? methods:...

Background. Evidence-based information on genetic sensorineural hearing loss in Latin America is limited, hindering the advancement of related clinical practice and development relevant healthcare policies field. This study describes sociodemographic characteristics a group Chilean participants with congenital, childhood, progressive or late-onset unknown etiology; all non-genetic causes were e...

OBJECTIVES/HYPOTHESIS To describe cochlear nerve deficiency and abnormalities of the internal auditory canal (IAC) associated with CHARGE (coloboma, heart defects, atresia choanae, retardation of growth and/or development, genital hypoplasia, and ear anomalies and/or deafness) syndrome. STUDY DESIGN Case series. METHODS In a tertiary children's hospital, children with CHARGE syndrome were e...

Although conventional structural MRI provides vital information in the evaluation of congenital sensorineural hearing loss (SNHL), it is relatively insensitive to white matter microstructure. Our objective was to evaluate possible changes in microstructure of the auditory pathway in children with congenital sensorineural hearing loss (SNHL), and the possible distinction between good and poor ou...
