IMPLEMENTATION OF NOVEL ALGORITHM FOR AUDITORY COMPENSATION IN HEARING AIDS USING STFT ALGORITHM

Audiogram is the graphic record drawn from the results of hearing tests with an audiometer, which charts the threshold of hearing at various frequencies against sound intensity in decibels.

description	Audiogram is the graphic record drawn from the results of hearing tests with an audiometer, which charts the threshold of hearing at various frequencies against sound intensity in decibels. This paper presents the work on auditory compensation (also known as audiogram equalizer) implemented with the help of Short Time Fourier Transform (STFT) algorithm. For humans normal hearing ranges from -10dB to 15dB, although 0dB from 250Hz to 8 kHz is reckoned as the average normal hearing. An audiogram is obtained to determine the frequency range the listener is audibly challenged to. STFT algorithm is employed to determine the frequency range of audio signal which is to be selectively amplified as per the audiogram. The present work uses verilog language to implement STFT algorithm. The entire system is developed on Zynq Evaluation and Development Board (Zedboard) using Vivado.
