چکیده
This paper describes a design of digital hearing aids. This study shows that design of Infinite Impulse Response (IIR) digital filter with Teaching-learning-based-optimization (TLBO) gives good result in digital hearing aids. TLBO algorithm is used to optimize the filter coefficient of IIR filter. The error between desired magnitude response and actual magnitude response will be minimized by this algorithm. Three audiograms have been used to verify that high accuracy can be achieved with direct IIR filter. The results of our study indicate that proposed design is much simpler and able to maximize hearing.
