Validity of pure-tone hearing screening at well-child visits.
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...
متن کامل[Subjective intraoperative hearing self-assessment in patients after stapedotomy comparing to postoperative pure-tone audiometry].
UNLABELLED In otosclerosis patients the most common procedure followed at Otosurgical Dept. Medical University of Lodz is stapedotomy with insertion of teflon-piston prosthesis. When surgery is finished a whisper hearing test is done from the 1 meter distance for brief intraoperative hearing improvement assessment. There is a number of patient who report subjective intraoperative hearing improv...
متن کاملPure-tone octave masking in listeners with sensorineural hearing loss.
Pure-tone octave masking was investigated in 14 listeners with sensorineural hearing loss to examine the hypothesis that the sensorineural ear introduces abnormal harmonic distortion. Thresholds for a test signal at f2, masked by a masking signal at fl, (where fz = 2fl ) were obtained as a function of the level of the fl masker for four different ft frequencies (250, 500, 1000, and 2000 Hz) and...
متن کاملPure tone pitch perception and low-frequency hearing loss.
Pitch perception for pure tones was investigated in a group of listeners with low-frequency sensorineural hearing loss. Pitch judgments from each listener were compared with results from psycho-acoustic tasks which provide information on the "place" of cochlear response. The pitch measures employed were: (1) binaural pure-tone pitch matching in a listener with unilateral hearing loss, (2) octav...
متن کاملPure-tone octave masking in normal-hearing listeners.
Octave masking was investigated at four different frequencies (250, 500, 1000, and 2000 Hz) as a function of intensity of the masker and phase of the test signal. Slopes of phase-locked octave masking were found to increase with masking signal frequency, from 0.80 dB/dB at 250 Hz to 3.0 dB/dB at 2000 Hz. The monaural octave-masking phase effect was considerably larger for masking signals at low...
