Computer-based audiometry allows for novel applications, including remote testing and automation, that may improve the accessibility and efficiency of hearing assessment in various clinical and occupational health settings. This study describes the validity of computer-based, diagnostic air and forehead bone conduction audiometry when compared wtih conventional industry standard audiometry in a...

An Audiometric Survey was carried out on two batteries of 4 Fd Regt RA (n-84) who were exposed to massive levels of impulse noise during "OP CORPORATE". A control group (n-30) was obtained from the remaining battery which did not serve in the Falklands, and it was matched well in age, service and job. They completed a questionnaire, were physically examined and had an audiogram using the MAICO ...

INTRODUCTION Tinnitus is a difficult to treat symptom, with different responses in patients. It is classified in different ways, according to its origin and associated diseases. OBJECTIVE to propose a single and measurable classification of persistent tinnitus, through its perception as sounds of nature or of daily life and its comparison with pure tone or noise, of high or low pitch, present...

Measures of the sound pressure level (SPL) near the eardrum were determined at discrete frequencies between 500 and 4000 Hz on 50 ears using TDH-39P and ER-3A earphones with the attenuator of an audiometer fixed at 90 dB HL. Results revealed significant differences in the measured SPL between the two earphones at all test frequencies. Results also revealed large intersubject differences in the ...

OF THE many diagnostic instruments now available to the practitioner none is so satisfactory to use as the audiometer. Antibiotics and the affluent society may be responsible for the virtual disappearance of acute mastoiditis in children as seen by the general practitioner in south-east England, but deafness is still common in adolescents. A child who has apparently recovered from acute otitis ...

Portability of equipment is an increasingly important component in the practice of audiology. We report on a new device, the OtoID, that supports evidence-based ototoxicity testing protocols, provides capability for hearing testing on the hospital treatment unit, and can automate patient self-testing. The purpose of this article is to report on the validation and verification of the OtoID porta...
