The present invention relates to a method of establishing a hearing ability model for a person, the method including providing a representation of the distribution of hearing ability for a population of individuals. The method may comprise the steps) performing a hearing evaluation event, comprising a stimulus of a person tested and a conscious and/or subconscious response of the person, ii) registering an observation of the response related to the hearing evaluation event, and iii) establishing a hearing ability model representing the hearing ability of the person, based on the observation related to the hearing evaluation event and the representation of the distribution of the hearing ability for the population. Further the present invention relates to a system for establishing a hearing ability model of the hearing ability of a person. The system may comprise a data storage configured to store a representation of the distribution of the hearing ability of a population of individuals, a hearing evaluation device configured to perform a stimulus of a hearing evaluation event, a response observation device configured to observe and/or register a response related to the hearing evaluation event, and a processor configured to establish a hearing ability model representing the hearing ability of the person based on the observation related to the hearing evaluation event and the data set.
