Simply increasing the size of a sound bore has no appreciable effect on the hearing aids response in the high frequencies. This finding is consistent with tubing resonances associated with the small internal diameter of the thin tube, which needs to be accounted for during the fitting process by possibly increasing gain in that frequency region through adjustments using the fitting software.
