[Merv and Sharon]

Your employer is wrong Ralphy. The problem with most plugs is that they are not individually moulded (disposables) and also if they they are well made and then fit really you well and fully occlude, you can hear little speech from other workers. Muffs cover a greater range of frequencies and give greater protection but they need to be good ones as well. They are also not very comfortable. Both could be good!
