Patent ID: 7605812

Claim:
A method for automatically modeling performed by a computer a hearing aid shell to create the hearing aid shell from the model, comprising: receiving a 3D geometric description of an undetailed hearing aid shell model; automatically extracting features and associated descriptors from the received shell model; classifying the extracted features by breaking the 3D geometric description into finite elements, and performing comparative operations on adjacent elements to discern the features; querying a database to determine if a stored shell model matches the received undetailed shell model or if stored features match one or more of the extracted features, and if yes, then implementing specific rules that have been previously stored and associated with the matched shell model or features on the received shell model to create the hearing aid shell model; if no, then implementing generalized binaural modeling rules based on the classified features to create the hearing aid shell model; and creating the hearing aid shell from the hearing aid shell model.
