Abstract
The hearing aid system is used for hearing impair patient communication, but the hearing aid's main issues are improper communication, power dissipation, delay, matching error, and low complexity. Many existing filter bank techniques are developed to overcome these issues but still have the problem of delay, unwanted noise, etc. This paper has designed a Tuned Feed forward Variable Bandwidth Filter (TFVBF) to enhance the Hearing Aid System (HAS) by reducing unwanted noise, matching error, and complexity. Moreover, the developed technique is implemented in MATLAB and it achieve low rate in power consumption and delay. Thus, the gained performance metrics has enhanced the HAS's performance by reducing, unwanted noise, matching error, and complexity. Finally, the attained performance metrics of the developed technique using 50 bands are compared with existing replicas in terms of matching error, delay, power consumption, and complexity for checking the effectiveness of developed replica.
