Patent ID: 8687833

Claim:
A method of providing information for a fitting process of an individually shaped ear piece of a hearing device characterized by storing information for the fitting process during a manufacturing process of the individually shaped ear piece into a data storage means, the data storage means being arranged at the individually shaped ear piece, the information for the fitting process being at least one of: a diameter of a vent within the ear piece, a length of the vent, design information of an ear canal, an acoustic vent mass (AVM), a length of a shell of the ear piece, a design of the shell of the ear piece, a kind of hearing device to be used with the ear piece, a kind of receiver used within a hearing system or the ear piece, a side of the hearing device or the ear piece (right or left), a producer of the hearing device or the ear piece, a vent loss, a reduction of occlusion effect, a real ear occluded gain, a real ear to coupler difference for low frequency range, a microphone location effect, beamforming correction, an estimation of residual volume and distance to ear drum, a real ear to coupler difference for high frequency range, an estimation of feedback threshold, or an open ear gain.
