Hearing aid for controlling hearing sense compensation with suitable parameters internally tailored

A hearing aid comprising:

• an acoustic signal-to-electric signal converting means for converting a first sound to a first electric signal, and implemented by a microphone;
• an electric signal-to-acoustic signal converting means for converting a second electric signal to a second sound, said electric signal-to-acoustic signal converting means including an earphone;
• a signal modifying means connected between said acoustic signal-to-electric signal converting means and said electric signal-to-acoustic signal converting means, and responsive to a third electric signal representative of hearing aid parameters so as to modify said first electric signal to said second electric signal, said signal modifying means including an analog-to-digital converter connected to said microphone for converting said first electric signal from an analog form to a digital form, a signal modifier connected to said analog-to-digital converter and responsive to said third electric signal for modifying said first electric signal to said second electric signal compensating a hearing sense of a user, an amplifier connected to said signal modifier for amplifying said second electric signal and a digital-to-analog converter connected to said amplifier for converting said second electric signal from said digital form to said analog form;
• a memory means including a plurality of memory sub-means for respectively storing a plurality of pieces of hearing aid data information in a readable manner;
• a working condition modifying means responsive to an instruction for working conditions for producing a fourth electric signal representative of a ratio of interpolation;
• and
• a parameter generating means responsive to said fourth electric signal so as to produce said third electric signal from said plurality of pieces of hearing aid data information through an interpolation at said ratio represented by said fourth electric signal,
• wherein said working condition modifying means includes a switching means for generating a fifth electric signal representative of said working conditions, an instructor connected to said switching means for producing said fourth electric signal and a sixth electric signal representative of a user's request for modification, and a first controller connected to said instructor for receiving said sixth electric signal,
• wherein said memory means and said parameter generating means are configured to cause said parameter generating means to produce said third electric signal,
• wherein said parameter generating means includes an interpolator, supplied with said pieces of hearing aid data information and responsive to said fourth electric signal for carrying out said interpolation, and a second controller connected to said interpolator for producing said third electric signal from the result of said interpolation, and
• wherein said ratio of interpolation is computed by said instructor based on receipt of said sixth electric signal which corresponds to the user's request for modification of said working conditions, the user's request for modification being inputted through said switching means.
