Ya know they use to make BIG ears, for hearing issues, could use them and cut them down, one smaller for the better ear..
They had a few different names...
The best thing you can do.. Take care of what you got left.. You can learn to listen around it.. believe it or not.. You’ll learn... I’m a retired HD mechanic, you know how many of my fellow mec friends are deaf, A LOT. NO MORE LOUD.. plug those babies... I lived with muffs and plugs my whole life....Still do in my personal shop.. I never waver.. Take care of them FIRST....I’m 65 and still hear above 16KHZ, and some lose in the 60-200hz region, very little... No leaf blowers, lawn mowers, gunshots (especially magnums), heavy equipment idling or just running.. concerts (partial plug um). Be wise....
