'Quasi free-field' audiometry: proposal for a modified transducer system. 1984

E De Seta, and G A Bertoli, and R Filipo

The authors studied a group of 13 young adults by using high-frequency techniques in 'quasi free-field' conditions, as suggested by Osterhammel, and comparing the results with those obtained by means of an original method suggested by the present study group. The data relative to this last-mentioned technique confirmed it as being valid on the grounds of test-retest findings and standard deviation. It is concluded that both methods are equally effective for the study of the physiology of the ear, but that the present method is less practical from the clinical point of view.

D001299 Audiometry The testing of the acuity of the sense of hearing to determine the thresholds of the lowest intensity levels at which an individual can hear a set of tones. The frequencies between 125 and 8000 Hz are used to test air conduction thresholds and the frequencies between 250 and 4000 Hz are used to test bone conduction thresholds. Audiometries
