Terms & Conditions.
When used properly, EarPeace reduces sound pressure by 75% while maintaining sound quality. EarPeace has a federally required Noise Reduction Rating of 11 to 17 decibels. This means that 80% of people will get more than 11 decibels of protection and 20% of people will get more than 17 decibels of protection. This range is due to variables such as ear canal size and proper adherence to instructions. Each order comes with two cases; each case has one set of earplugs plus one extra plug. Plugs are made of hypoallergenic silicone. Case is made of aluminum.
