Hi Anjali,
As you are designing a filter for hearing-aid, a better choice would be to choose an adaptive filter. You can follow this link for designing an adaptive filter
https://www.mathworks.com/help/dsp/ug/overview-of-adaptive-filters-and-applications.html
You can even design your own filter using “filterDesigner”, specifying the type and order of filter, frequency specifications and many more. Here is the link to “filterDesigner” documentation:
