6.4.2.5 The Table

These tables hold the numerical values of the response probability and noise reached for each of the stimuli
presented.
In the example shown below the lowest intensity that provided a response for 500Hz is 15dB, for 1000Hz is
25dB, for 2000Hz is 25dB, and for 4000Hz 15dB is the indicated in green.
When no detection occurs, e.g. 15dB at 1kHz only made it to 56% of the response criteria and is therefore
indicated in red. If the same intensity is tested more than once, then the one with the lowest noise will be
shown in the table if of the same if all are a Refer result.
But should both a Pass and Refer be present on the same frequency a Pass is automatically shown in the
table.
Next to the detection score the noise is calculated and displayed during testing.
Stop criteria
Some clinics use a stop criteria of 15nV for residual noise, when testing with multiple stimuli on adults
(both 40Hz and 90Hz). If however the response values are higher than 80% or exhibit steady growth as a
function of reduced residual noise, then lower residual noise values may be more appropriate before decid-
ing to stop the test.
For sleeping children/new-borns, a stricter stopping rule of 10nV for residual noise is often applied, as
this can typically be achieved within a reasonable time frame.
The color coding is the same as on the graphs, so ongoing recordings are black, recordings at 100% are
green and curves not reaching 100% are red.
