How many hearing tests can you do in a session?

It depends on a number of factors such as how long we need to drive to get there and whether shifts are worked, but as a guide, for a large site with shifts being worked, the maximum we can do in a week is around 200. To do that we have two technicians operating one unit, one doing days and then the second doing evenings and nights so we are in effect testing from 9am to about 1.30am each day.
