Alternatively, continuously rubbing a piece of paper between the thumb and index finger produces a consistent broadband sound. If the tragus is rubbed at the same time, this will provide sufficient masking in most tests except for use of a loud voice. Masking the other ear: putting a finger in the other ear is insufficient.This may be used for initial assessment but formal audiometry is preferable.It is possible to have scores less than 0, which indicates better-than-average hearing. Hearing loss of 100 dB is nearly equivalent to complete deafness for that particular frequency. Normal hearing: less than 25 dB in adults and 15 dB in children.The hearing level is quantified relative to 'normal' hearing in decibels (dB), with higher numbers of dB indicating worse hearing. Methods of hearing assessment in infants and young children are discussed in the separate Hearing Testing and Screening in Young Children article. Other relevant separate articles include Hearing Problems and Deafness in Children.
There is a high rate of occult hearing loss in the elderly, who report sadness, depression, social isolation and insecurity physical, emotional, mental and social well-being all improve once hearing aids are used. As well as ensuring effective screening for problems in children, it is essential to consider and arrange appropriate tests for any child or adult with possible hearing impairment. Hearing impairment may be very variable in severity but can cause severe communication difficulties leading to profound educational, social and psychological problems.
