Age of Hearing
Determine the ‘biological’ age of ears based on the hearing threshold of a person
To determine the biological age
of a person’s ears the tool compares the current hearing threshold with the statistical distribution of hearing thresholds related to age and gender (ISO 7029:2017)
Chronological age is the number of years a person has been alive. The biological age takes many lifestyle factors into consideration including bad listening habits (loud music) and exposure to noise at work.
The distribution of hearing thresholds in relation to age and gender for otologically normal persons within the age limits from 18 years to 80 years and for the range of audiometric frequencies from 125 Hz to 8 000.
This tells how many additional years need to be added to the chronological age due to exposure to high noise levels. Or, if people hear better than usual at this age, they have younger ears.
This makes it much easier for professionals to explain the result of the hearing test (i.e. audiogram), motivate people to protect their ears and encourage behavioural change.
