Hi

I am extremely sorry to inform you dear but with 70% hearing impairment you are not eligible for Neet examination and thus you can't be a doctor

:(

This is because,

To be eligible for Neet examination , your hearing a impairment should have been less than 40% ,

Those with equal to or more than 40% of hearing impairment are not eligible for Neet examination.

Now,

your hearing impairment is 70 i. e more than 40 % and thus you are not eligible.

You can check the same on the page number 88  of neet 2021 information brochure.
