UNLABELLED The authors evaluated pure tone audiometry with and without specific ear protectors. AIM The purpose of this case control study was to measure the level of sound attenuation by earplugs. MATERIAL AND METHODS The evaluation included sixty ears of 30 subjects of both sexes, aged between 20 and 58 years, of various professional activities, with normal hearing thresholds, and followi...

OBJECTIVE To estimate the sensitivity and specificity of pure-tone audiometry hearing screening in the primary care setting. DESIGN Prospective cohort study. SETTING Eight academic and private pediatric practices. PARTICIPANTS A subset of children from a convenience sample of 1061 children between 3 and 19 years of age were screened for hearing loss using pure-tone audiometry. Interventio...

A cross-sectional study was conducted on patients attending a primary care facility to determine the prevalence of self reported hearing loss using a single question, "Do you have hearing loss?" Pure tone audiometry was performed to compare the accuracy of the self report. A total of 111 patients were recruited. The prevalence of self reported hearing loss using a single question and pure tone ...

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...

OBJECTIVES This study directly compared the accuracy of two audiometry-based tests for screening school children for hearing impairment: the currently used test, pure tone screen and a device newly applied to children, HearCheck Screener. DESIGN Two-gate case-control diagnostic test accuracy study. SETTING AND PARTICIPANTS Hearing impaired children ('intended cases') aged 4-6 years were rec...
