Hearing device and method for tuning hearing device par

A method for tuning a hearing device, comprising:

• obtaining a model comprising a parameterized objective function;
• obtaining a first test setting comprising one or more first test hearing device parameters;
• obtaining a second test setting based on the model, the second test setting comprising one or more second test hearing device parameters;
• outputting a first test signal according to the first test setting;
• outputting a second test signal according to the second test setting;
• obtaining a user input indicative of a preference for the first test setting or the second test setting as a preferred test setting;
• updating the model based on the preferred test setting;
• and
• updating the hearing device based on information associated with the preferred test setting;
• wherein the objective function ƒ{circumflex over (X)},Λ(X) is given by:
• ƒ{circumflex over (X)},Λ(X)=−((X−{circumflex over (X)})TΛ(X−{circumflex over (X)}))p,
• where X is a D-dimensional vector, {circumflex over (X)} is an argument of ƒ{circumflex over (x)},Λ, Λ is a D×D matrix, D is an integer, and p is a real-valued exponent.
