A kind of design criterion for WOLA filterbanks used in digital hearing aids
Jie Cui · Applied Acoustics · 2010
A kind of design criterion for WOLA filterbanks used in multi-channel processing of digital hearing aids is presented.According to the new design criterion,the filter can be designed by window function,and the design can be simplified to the choice of windows lengths.Simulations of the two cases of amplification in multi-channel of linear chirp signal and speech signal are carried out.The results validate that the output signals of the designed filterbanks achieve the processing aim and have no aliasing.
