WEBER EXPERIENCE

From Big Medical Encyclopedia

WEBER EXPERIENCE (E. The N of Weber, 1795 — 1878, is mute. the anatomist and the physiologist) — a method of differential diagnosis of defeats of the sound carrying out and sound perceiving departments of an ear by means of the sounding tuning fork or bone phone of the audiometer. It is offered by E. Weber in 1829. At V.'s statement by the lake use a tuning fork of a low tonality more often. The leg of the sounding tuning fork is put on the middle of a darkness (or on a nose bridge or the middle of a chin). In the absence of pathology of an ear or at uniform decrease in hearing on both sides inspected hears a sound of a tuning fork equally in both ears; at the same time he specifies that he hears a sound in the middle of the head (lateralization of a sound does not occur). At hemilesion of the sound carrying out device (e.g., at purulent average otitis) the sound of a tuning fork will be heard in a sore ear, at bilateral defeat — in worse the hearing ear (lateralization is worse than the hearing ear aside). At hemilesion of the sound perceiving device the sound of a tuning fork will be better perceived by a healthy ear, at bilateral defeat — it is better the hearing ear (lateralization is better than the hearing ear aside).

Century of the lake can be made also by means of bone phone of the audiometer. Unlike tuning forks which fluctuations quickly fade the sound at a research the audiometer has constant loudness that allows the patient to define his lateralization more precisely. Results in. lakes on «the acoustical passport» note the shooters sent to the relevant party.
