Shvabaha experience

Shvabaha experience (D. Schwabach) is a method of differential diagnosis between defeat the conductive and sound perceiving device. Is to compare the duration of the perceived audio tuning fork through the bone in healthy and sick. For this pre-define the time of perception through the bone sound tuning fork With128 normal hearing and believe it is time to sound normal. For production experience leg tuning fork put on the crown studied and noted the time, during which the patient hears the sound of a tuning fork. If he hears the sound for a shorter time than the normal ("Schwabach shortened"), indicate disease sound perceiving device. If he hears the sound longer standards ("Schwabach extended"), this says about the disease sound carrying out device. Time perception of sound tuning fork through the bone of the patient can be compared with the time of the perception of normal hearing your doctor.
