Abstract:
1. An automated fitting procedure for a hearing aid device, comprising: providing initial setup for the hearing aid device; the initial setup includes at least calculating initial settings from hearing loss data, performing an ear environment calibration, or playing sound samples in background; searching for optimized volume settings using first predefined volume step sizes selected to provide convergence toward the optimized volume settings; searching for optimized volume settings using second predefined volume step sizes selected to refine the optimal volume settings, the first predefined volume step sizes being larger than the second predefined volume step sizes; searching for optimized equalization settings using first predefined equalization step sizes selected to provide convergence toward the optimized equalization settings; searching for optimized equalization settings using second predefined equalization step sizes selected to refine the optimal equalization settings, the second predefined equalization step sizes being smaller than the first predefined equalization step sizes; and programming the hearing aid device for calibration and acoustic feedback cancellation in accordance with the optimized volume settings and the optimized equalization settings; wherein said optimized volume settings and said optimized equalization settings each include at least a first, second, third, fourth, and fifth setting, respectively, and said searching for optimized volume settings and said searching for optimized equalization settings each comprises conducting adaptive paired comparisons, including: comparing said first setting to said second setting; if said first setting is preferred, comparing said first setting to said fourth setting; if said first setting is still preferred, applying said first setting; if said fourth setting is preferred instead, comparing said fourth setting to said fifth setting; if said fourth setting is still preferred, applying said fourth setting; and if said fifth setting is preferred instead, applying said fifth setting.
