Classical T/C level fitting for children: play audiometry
When a child is old enough (roughly it should be possible to do play audiometry at the age of 2 years, but obviously it depends on the developmental skills of the child in question), he or she can be conditioned to perform a certain task upon hearing the stimulus, for instance putting a peg in a board. This can be a very reliable indicator for thresholds if the task is performed well, but is very time consuming since the child needs to be trained and each electrode needs to be tested. Also, for setting C-levels the method is less reliable since most children will not have the cognitive skills and/or auditory experience to judge ‘comfortable loudness’. One option is to have the child point to ‘scaling pictures’ such as the ones displayed below, but this may be very hard to do with very small children, scaling loudness is more difficult and requires more skill from the child than just indicating threshold through play audiometry.
Example of paediatric loudness scale pictures.
Advantages: Can be reliable in setting T-levels.
Disadvantages: Time consuming, not suitable for the youngest children, setting C-levels is more difficult.
