The reason thos jackhammer operators use hearing protection is because it is a constant noise. As a noise continues it builds up the damage. a constant jackhammer noise would eventually damage the ear while a shorter duration may cause slight adn temporary hearing loss. Biggest mistake I made was not wearing hearing protection when firing a 7 mm mag in a box blind. The gun has porting/muzzel brake and the noise bounced off the wall and came back to me and my dad. we both have lost hearing in our left ear but my dad has had some other things happen that aggravated it.
