Pure Tone Audiometry

چکیده
Pure tone audiometry is the standard behavioral assessment of an individual’s hearing. The results of pure tone audiometry are recorded on a chart or form called an audiogram. In most cases a pure tone audiogram is easy to obtain and provides information about peripheral hearing acuity across the frequencies used in speech. It allows for a quick view of how well, or how poorly, an individual can hear specific frequencies and for a comparison of one ear to the other. In the presence of a hearing loss, the pure tone audiogram often allows a clinician to make some inferences which, when viewed in conjunction with the patient’s case history, can help lead to a diagnosis or determine the likely etiology of the hearing loss. The following is a summary of how a pure tone audiogram is obtained and interpreted.

Theory and practice of pure tone audiometry
Pure tone audiometry indicates what hearing thresholds (dB) are required to just be able to perceive a tone at different frequencies (Hz). A pure tone audiology threshold at a specific frequency is the decibel level at which a sound is perceived 50% of the time. The decibel scale used in pure tone audiometry is dB Hearing Level (dB HL). The dB HL intensity scale is based on normal human hearing...
متن کاملComparing pure-tone audiometry and auditory steady state response for the measurement of hearing loss.
OBJECTIVE To compare pure-tone audiometry and auditory steady state response (ASSR) to measure hearing loss based on the severity of hearing loss in frequencies. STUDY DESIGN AND SETTING A total of 105 subjects (168 ears, 64 male and 41 female) were enrolled in this study. We determined hearing level by measurement of pure-tone audiometry and ASSR on the same day for each subject. RESULTS P...

متن کاملPure tone audiometry and impedance screening of school entrant children by nurses: evaluation in a practical setting.
BACKGROUND Screening for hearing loss in English children at entry to school (age 5-6 years) is usually by pure tone audiometry sweep undertaken by school nurses. This study aimed to compare the validity and screening rates of pure tone audiometry with impedance screening in these children. METHODS Two stage pure tone audiometry and impedance methods of screening were compared in 610 school e...
متن کاملEvaluation of pure tone audiometry and impedance screening in infant schoolchildren.
STUDY OBJECTIVE The aims were (1) to evaluate impedance measurements against pure tone audiometry as a screening method for the detection of middle ear changes associated with hearing loss in infant school children; (2) to estimate the costs of the health authority of each method. DESIGN The study involved two stage screening in which both methods were offered, pure tone audiometry being carr...
