Abstract: | A new four-channel loudness compensation method was proposed based on human auditory,especially on presbycusis.The filter-bands designed for sub-band loudness compensation was given by using quadrature minor filter bank(QMFB).The signal at senile hearing loss was SIMULATE d using a LOW-PASS FILTER.Results of simulation and experiments on DSP show that,energy loss in high bands of hearing loss patients is well compensated. |
