Where are you getting that you don't need hearing protection (again, talking center fire)? This is from the SilencerCentral webpage:
Shipped to YOUR Front Door. Nation’s Best Selling Multi-caliber 100% Titanium User-Servicable Silencer. Tested Quietest & Lightest. Pay While You Wait!
www.silencercentral.com
The BANISH 30-GOLD brings a user-serviceable, quick-detach suppressor design that is lighter weight, shorter, and quieter than anything we have ever tested. You won’t find a lighter and quieter can anywhere!
An exceptionally versatile suppressor, the BANISH 30-GOLD is rated for calibers from rimfire up to 300 RUM. All BANISH suppressors have been designed for unmatched sound suppression, and testing shows that the BANISH 30-GOLD reduces the report by 36 decibels. The average sound level heard by shooters from the BANISH 30-GOLD is 132.9 decibels!
133db is far louder than what anyone recommends the need for hearing protection.
So I'm curious how you are finding otherwise.
