Protocol Scoring Rules
OAE1: GSI Default
■ Scores the test result as PASS when all three responses are at or above the
Pass/Refer line and each response is individually scored as a Pass.
■ Scores the test result as REFER when at least one response is below the Pass/Refer
line and its response is individually scored as a Refer.
■ Scores the test result as NOISE when at least one response is individually scored as
noise.
OAE4: 2 OUT OF 3
■ Scores the test result as PASS when at least 2 out of 3 responses are at or above the
Pass/Refer line and these 2 responses are individually scored as Pass.
■ Scores the test result as REFER when at least 2 out of 3 responses are below the
Pass/Refer line and these 2 responses are individually scored as Refer.
■ Scores the test result as NOISE when at least 2 out of 3 responses are individually
scored as Noise.
■ If one response is PASS, one is REFER, and one is NOISE, the test result is scored
as NOISE.
Selection of protocol OAE 1 versus OAE 4 depends upon the program's
performance objective for hearing screening.
It is possible to save and print one ear with OAE 1 and the other ear with
OAE 4.

protocols and may be overwritten.
The OAE 4 protocol is loaded into the GSI 70 DMS program when the first
test results for OAE 4 are collected from the Screener.

Protocol Scoring Rules
OAE1: GSI Default
■ Scores the test result as PASS when all three responses are at or above the Pass/
Refer line and each response is individually scored as a Pass.
■ Scores the test result as REFER when at least one response is below the Pass/Refer
line and its response is individually scored as a Refer.
■ Scores the test result as NOISE when at least one response is individually scored as
noise.
OAE 4: 2 OUT OF 3
■ Scores the test result as PASS when at least 2 out of 3 responses are at or above the
Pass/Refer line and these 2 responses are individually scored as Pass.
■ Scores the test result as REFER when at least 2 out of 3 responses are below the
Pass/Refer line and these 2 responses are individually scored as Refer.
■ Scores the test result as NOISE when at least 2 out of 3 responses are individually
scored as Noise.
■ If one response is PASS, one is REFER, and one is NOISE, the test result is scored
as NOISE.
Selection of protocol OAE 1 versus OAE 4 depends upon the program's
performance objective for hearing screening.
If the results for the left and right ears are run with both default protocols
(i.e., OAE 1 and OAE 4), the right and left ear results will be paired for printout in
the time sequence that they were acquired.
