If the patient responds before the signal is presented, the message

2.3.2 Automatic Screening
Screening audiometry is a quick and simple way to identify patients in need of thorough audiological evaluation.
The test involves presenting tones at a predefined Hearing Level, the screening level. The patient is either able or unable
to hear the presented tone. The results show whether the Hearing Thresholds are better or worse than the defined
screening level.
Screening audiometry can be combined with Threshold determination of the frequencies where the screening level is not
audible.
