    Presbycusis or age-related hearing loss is a bilaterally symmetric sensorineural hearing loss associated exclusively with age, excluding any other causes of hearing loss. Presbycusis is very relevant because of its high prevalence, and its consequences (e.g., alterations in communication, social isolation, depression, dementia), and the economic impact. This paper reports the first attempt to estimate the prevalence of presbycusis in an otologically normal population, i.e., without previous ear disease, exposure to noise, or potentially ototoxic substances, or familial hearing loss. A total of 4290 subjects from 5 to 90 years old were included in the study. No statistically significant differences were found between right and left ear, nor between males and females, in any of the age groups. Presbycusis was detected over 60 years following the WHO classification; although the results vary depending on the classification used. Moderate hearing loss (≥ 41dB) was detected in the population over 72 years. None of the subjects had severe or profound hearing impairment. The prevalence of presbycusis increased with age, being 100% in individuals aged 80 years and older. The prevalence of presbycusis is highly variable depending on the pure-tone averaged frequencies and the classification system used; therefore, a common classification system should be used. An otologically normal population is needed to establish the prevalence of presbycusis as in non-screened populations it is the hearing level including all types of hearing loss that is measured, but not presbycusis itself.
