Protocol and Instructions
for the BAER Tester
Dogs must be evaluated by
brainsterm auditory evoked response (BAER). Bone stimulation transducer
will be used in addition when conduction deafness is suspected
The examiner must be a person
recognized by the GDC to have expertise in the use of both systems of testing
and is agreeable to using the current GDC protocol. A list of acceptable
testers is available from GDC.
testing is done on canines at least 35 days old
signal sound presure level between 70 and 105 DB is used to obtain a response
with peaks I through V judged present at their appropriate latencies.
earphones will be used
restraint is optional.
work is done in such a manner that movement will not cause an artifact
that could be mistaken for a repopnse to a stimulus.
least 200 clicks will be used to obtain the response
masking tone is not considered necessary if recordings are made with electrodes
positioned along the midline and in the ipsilateral mastoid region; a masking
tone is necessaary if the electodes are placed along the midline at the
vertex and at T-1.
appropriate circumstances when an ear tests as deaf using air-conducted
stimuli and the possibility of conduction deafness exists (chronic otitis,
excess ear wax accumulation),
repeat testing with a bone stimulation transducer is recommended.
printed copy of the BAER Test tracing will be provided to the owner and
By certifying that a dog
has BAER BILATERAL hearing, the professional performing the test is making
this statement in accordance with their best clincal judgment. The GDC
has a system for appeal if there is significant reason to question the
GDC registration please mail:
this GDC application/release form, signed
by owner and the Tester:
a copy of the BAER test tracing;
a check for the appropriate
amount according to the attached fee schedule.
