Abstract Background Rheumatoid arthritis (RA) is an inflammatory autoimmune disorder that has cardinal articular and peri-articular symptoms. Extra-articular manifestations (EAMs) are also reported among RA patients. In the current study, we assessed hearing function in 50 An extensive audiological assessment including pure tone audiometry (PTA), extended high-frequency (EHFA), tympanometry, ac...
CONCLUSION High frequency immittance measurements demonstrate promise in clarifying middle ear status for neonates but age- and gender-specific norms should be consulted. OBJECTIVE To describe high frequency immittance measurements using a 1000 Hz probe tone for a sample of 278 neonatal ears (0-4 weeks of age) in order to compile normative tympanometric and acoustic reflex criteria. SUBJECT...

The recent discovery of oto-acoustic emissions [see Zurek, J. Acoust. Soc. Am. 78, 340-344 (1985)] and the newer measures of the micromechanics of the inner ear have generated renewed interest in quantitative descriptions of the biomechanics of the cochlea. Active elements (mechanical force generators) are thought to be essential for producing the high sensitivity and sharp tuning typically ass...
