Absolutely sir. I think the Otologist I cited has published some of his studies in some journals on hearing issues. He was one of the guys that developed the cochlear implants as well.
He became very passionate on hearing protection due to the fact he lost hearing in a hunting trip when a fellow hunter he was with fired a .375 H&H Mag about 24" from his left ear.
He felt there is some merit to physiological changes in ear canals on a daily which prompted him to stop recommending molded custom plugs.
I have raced high performance outboards since my teen years and greatly damaged my hearing from that along with shooting when young without hearing protection.
I still race and shoot a lot so I've taken his knowledgeable advice as to what is best for me to preserve what hearing I have left.
I had him make me a pair of custom plugs a few years back. I used them often, but still noticed that the protection would change from day to day as he said…..I could noticeably hear the sound difference each day when I would put them in. Some days they would fit nice and snug…other days they would fit loose. I wear some type of hearing protection on some days literally all day being around the performance outboards. I've gone to strictly using the Howard Leight plugs….but you gotta take the time putting them in right and holding them in your ear canals until they expand correctly. Even with speeds up to 100 mph in boats, I've never had them work their way out. To the contrary, I've had to pull them out with forceps at the end of a race day because they work further down my canals and I could not grab them with my fingers to remove them.
I will add that the doc also said everyone should consciously make sure that they shoot with their mouths closed as sound waves can travel up the Eustachian tube to the inner ear as well….an interesting point.
He is a very noted and well known Otologist/Neurologist and has had some ground breaking research and procedures in hearing and balance issues and also some ground breaking research in concussion protocols in athletes.
I know of some other audiologist that have come to the same mindset on custom plugs as well as he.
It will be great if you guys come up with a material to compensate for those subtle changes. Small differences in NRR Decibels can make a lot of difference in protecting your ears long term.
Good discussion sir. Thank you.
When you do bring your new product out I want to be one of the first to get them…I'll pay whatever to protect what hearing I have left!
I think you will be setting on a gold mine!!

Boat racing is like a beautiful woman.......expensive, high maintenance, but well worth the fun!
