the mean noise levels were measured in the different sections of six representative mills in the isfahan area, and audiometric measurements were made in 282 male workers employed in these mills. the mean noise levels were on average 95 dba in the weaving sections and 88 d ba in the spinning sections. the audiometric findings showed a significant loss of gearing in the textile workers as compare...

OBJECTIVE To further examine the reliability of categorical loudness scaling (CLS) for individual loudness categories and for the slope of the CLS functions. And, to evaluate the relationship between CLS and audiometric threshold. DESIGN CLS functions were obtained in 74 subjects, 58 with hearing loss and 16 with normal hearing. CLS functions were measured at three frequencies (1, 2, and 4 kH...

various dimensions of the human vestibular aqueduct were evaluated in two groups, patient and control, and these measurements were compared. both groups were examined clinically, followed by audiometric evaluation and temporal bone high resolution ct scan. it was found that in approximately one third of the patient group (with idiopathic snhl), the vestibular aqueduct was 1.5 mm or larger. also...

OBJECTIVE Supra-aural audiometric headphones are generally not recommended for use in measuring the attenuation of earplugs, because contact between the headphone and pinna and/or earplug could alter the attenuation obtained, and because of concerns of non-comparability between modes of excitation from supra-aural headphones and the sound-field procedure required by the standardized method. In ...

The early fitting of infants with hearing aids relies largely on the verification of amplification characteristics using simulated real ear measurements (REM) that are matched to prescription targets derived from audiometric thresholds. The audibility of different parts of the speech spectrum can be inferred from the audiometric thresholds and the estimated applied gain, and is expressed as the...

UNLABELLED Teachers frequently report auditory symptoms and excessive noise in classrooms, but noise level measurements are not done routinely. Study model - a prospective clinical trial. AIM To study auditory symptoms and audiometric exams of teachers and classroom noise levels. MATERIAL AND METHOD Data from two groups, GI (40 teachers) and GII (40 voluntaries) were studied as follows: age...

UNLABELLED Hearing loss in the elderly is one of the most incapacitating communication disorders, preventing them to fully perform their tasks in society. AIM This study aimed to determine what is the best tool that together with the audiometric tests better represents the hearing loss reported by the elderly and which frequencies in the audiometric test must be considered to determine the he...
