Presentation of the device
Audiometry is a behavioural test for the rapid assessment of hearing ability. Using an acoustic stimulator, sounds,
words or sentences at different sound intensities are presented to the subject. The subject reports his or her perception to
the operator who, depending on the test used, can determine an absolute threshold of perception or an intelligibility
threshold.
1.2.1
Intended use
The
AUDI
O
SCHOOL
is designed for screening, documentation and monitoring of hearing function. It is intended for
use by health care personnel in schools and workplaces who require a screening approach (large-scale screening cam-
paign). Screening audiometry is a behavioural test for rapid assessment of hearing ability. The subject is presented with
sounds of varying loudness via a stimulator. The subject transmits his or her perception to the operator, who can detect
normal hearing (20db threshold), or a decrease in hearing acuity by determining an absolute threshold of perception. In
screening, transduction is performed via the normal auditory pathway using an air conduction transducer.
The
AUDI
O
SCHOOL
is intended for the following audiological tests:
