COMD3700.2a Exam Study Guidewhen was the tuning fork adopted as an instrument for testing hearing? - Answer over a
century ago
A diagnostic statement made on the basis of a tuning fork is absolutely limited to.... -
Answer the pitch of the fork used because hearing sensitivity is often different for
different pitches
Schwabach Test - Answer (1890) bone-conduction test that compares the hearing of a
patient with that of an examiner
What does the Schwabach Test assume? - Answer that the examiner has normal
hearing, which is a major limitation of the test
normal Schwabach - Answer the examiner and the patient stop hearing the tone at
approximately the same time
diminished Schwabach - Answer patient stops hearing the tone much sooner than the
examiner; indicates patient has sensorineural hearing loss; hearing by bone conduction
is impaired
(Schwabach) diminished 10 seconds - Answer examiner hears the tone for 10 seconds
longer than the patient
why will some patients with conductive hearing loss hear the tone in the Schwabach test
longer than the examiner? - Answer in some conductive hearing losses, the patient's
hearing in the low-pitch range may appear to be better than normal
prolonged Schwabach - Answer patient hears tone longer than examiner; in some
conductive hearing losses the patient's hearing in the low-pitch range may appear to be
better than normal
Why is it difficult to interpret Schwabach results in the case of mixed hearing losses? -
Answer both inner ears are close together and embedded in the bones of the skull, so it
is impossible to stimulate one and not the other; therefore if there is a difference in the
sensitivity of the two ears, a patient will respond to sound heard through the better ear
which causes a false normal Schwabach
Rinne Test - Answer compares sensitivity by bone conduction to sensitivity by air
conduction; patients states whether tone sound louder when tuning fork is placed on
mastiod process or held next to the opening of the ear
positive Rinne - Answer (Rinne) patient hears louder tone when fork is held close to ear
than when it is placed on the mastoid process;
also occurs when patients have sensorineural hearing loss because the attenuation
produced by a problem in the sensorineural mechanism causes the same degree of loss
