From 2001 all employees who may be exposed to noise in their work
environment have been required to undergo hearing tests. The
legislation requires hearing tests to be performed by a competent and
registered audiometric technician using calibrated equipment. The
initial hearing test (the first test) is a Baseline. This comprises of
two hearing tests done on same day with a time interval between tests.
If the result is acceptable this test will be used throughout the
employees work life to determine the percentage (%) hearing loss.

to the Baseline is greater than 10% the employee must undergo a full
