• As with presbycusis, spatial hearing loss varies with age.
• Presbycusis is the second most common illness next to arthritis in aged people.
• The impact of presbycusis on communication depends on both the severity of the condition and the communication partner.
• This type of presbycusis is manifested by a low-frequency hearing loss, with unimpaired speech recognition.
• Elderly hearing loss has a fancy name, presbycusis, but surprisingly little is known about what underlies it.
• The cause of presbycusis is a combination of genetics, cumulative environmental exposures and pathophysiological changes related to aging.
• Classically, audiograms in neural presbycusis show a moderate downward slope into higher frequencies with a gradual worsening over time.

• Presbycusis and other such hearing-related problems promote social withdrawal, as individuals begin to lose touch with the world around them.
• The most common kind of sensorineural hearing loss is age-related ( presbycusis ), followed by noise-induced hearing loss ( NIHL ).
• Presbycusis is the most common cause of hearing loss, afflicting one out of three persons by age 65, and one out of two by age 75.
• Noise, along with heredity, may be a primary factor in presbycusis, or age-related hearing loss, the most common kind of hearing loss in industrial society.
• Discrediting earlier notions of presbycusis, Rosen demonstrated that long term hearing loss is usually the product of chronic exposure to environmental noise in industrialized countries ( Rosen, 1965 ).
• Over the past century, leading otologists and neurotologic researchers have argued whether the finding of SNHL late in the course of otosclerosis is due to otosclerosis or simply to typical presbycusis.
• However, a recent study found that diabetes, atherosclerosis and hypertension had no correlation to presbycusis, suggesting that these are nosocusis ( acquired hearing loss ) factors, not intrinsic factors.
• Hearing loss within the "'speech banana "'can also hinder communication capabilities in adults, as in elderly people with age-related hearing loss ( presbycusis ).
• The sound can typically only be heard by people below 25 years of age, as the ability to hear high frequencies deteriorates in humans with age ( a phenomenon known as presbycusis ).
• Presbycusis is age related hearing loss, it could be described as " acquired " and it can / does involve recruitment . talk ) 07 : 15, 14 November 2013 ( UTC)
• Although some presbycusis may occur naturally with age, in many developed nations the cumulative impact of noise is sufficient to impair the hearing of a large fraction of the population over the course of a lifetime.
