If suppressor usage is an irrational want, then why is their use mandated by law in several European countries that regulate firearms more strictly? Because they want to encourage assassination and poaching?
Short of stereos, I am not aware of any commercial product where the end user wants it to be louder than it has to be. Personally, I shoot my suppressed rifle with earplugs as well. You are still talking 110-100 decibels at the muzzle with suppressor and earplugs. With just suppressor or earplugs alone, you are barely under the OSHA standard for hearing safe.
I think you've been watching too many Hollywood movies Kochman.
