摘要:
There is provided a method for determining a noise exposure level associated as the cause of an observed evolution of hearing acuity of an individual of known gender. The method comprises the following steps: 1) providing a first audiogram of the individual measured at age X and a second audiogram of the individual measured at age Y 2) inputting the individuals gender, age X, and a time period equal to Y−X in a statistical hearing threshold levels evolution prediction formula 3) calculating projected hearing loss audiograms specific to each of a plurality of possible noise level exposure values, using the prediction formula 4) comparing a pattern of each calculated projected audiogram with a pattern the second audiogram 5) selecting the projected audiogram that best fits the second audiogram and 6) assuming that the noise exposure level value associated with the selected projected audiogram is the noise exposure value that caused the evolution of hearing acuity observed between the first and the second audiograms. There is also provided systems for performing the method and methods for providing services to clients or enabling users regarding determination of real ear noise exposure values.
