Anything requiring specialist playback systems (Surround, Atmos, Binaural, etc.) will require specific recording techniques and/or special mixing & playback equipment. (Yes, I know, all of you experienced audio types will say that it's just the placement of the sounds into the expanded sound space, but we are automatically thinking about the mix before we begin; neophytes don't think this way yet.) Unless your project is that one-in-a-billion quality plus lots-of-luck project, the odds are your film will be shown at mid and low level festivals with mediocre sound systems and, subsequently, on laptops, smart phones and ear buds, so the effect of high end "3D" audio will be lost.
Your blind protagonist has only hearing (at least in your project; in reality blind folks also rely on touch, taste and smell) so your project will require a highly "stylized" approach to the sound. This will occur mostly in the mixing state of the project, although great attention will need to be made to every other aspect of the production and post production audio. When you get to your protagonists POV the audio could/should become extremely defined. This MUST be supported by the visuals, at least in the initial part of the film, so that the audience understands the "sonic language" of the project - the blind protagonists aural perspective versus that of the other characters. There are many ways of accomplishing this, and you should probably use them all. As an example… When a large object, lets say a bowling ball, is dropped into deep water, you can hear the ball "slap" the water, the hollow "bloop" of the hole the ball makes, the "clap" as the water collapses back into the hole, the "rush" of the water climbing in to the air and finally the individual drops of water raining back into the body of water. This all happens in about 1.5 seconds Your blind protagonist will hear this amount of exaggerated detail of a water drop into a filled sink taking less than half a second. Most people just hear the heel/toe of a footstep, your blind protagonist will hear the entire "roll" of the footstep and every grain of sand being crushed/moved as well as the "swish" of clothing, breathing, etc.
Your protagonist will be extremely sensitive to every sonic detail of his/her world So, in my opinion, you will need to establish this POV both sonically and visually at the outset of the film to firmly embed the difference in the ears & eyes of the audience. You may want to check out "Daredevil" (2003); some good ideas there. There is also the TV series "Longstreet" (1971-1972) about a blind insurance investigator. He relied heavily on his guide dog, but a few interesting ideas there as well. (Just for fun, a fair number of 70s TV notables guest starred, including Bruce Lee.) You may also find this interesting; it's about a blind man who uses echolocation:
As a final suggestion you should spend a day blind; I did this twice and it is a fascinating journey.
Yes, I am available for consult and/or audio post and relatively affordable.
Good luck.
