Abstract
The tone decay test (in any case called the cutoff tone decay test or TTDT) is used in audiology to distinguish and measure hear-capable weariness. It was made by Raymond Carhart in 1957. In people with customary hearing, a tone whose power is only hardly over their complete constraint of hearing can be heard tenaciously for 60 seconds. The tone decay test makes an extent of the "decibels of decay", for instance the amount of decibels over the patient's all out constraint of hearing that are required for the tone to be heard for 60 seconds. A decay of some place in the scope of 15 and 20 decibels is definite of cochlear hearing setback. A decay of more than 25 decibels is illustrative of damage to the vestibulocochlear nerve.
