form plug

No single hearing protection device delivers by itself great protection against dangerous sound levels than disposable foam plugs. When inserted correctly into the ear canal, these inexpensive dandies reduce noise levels by about 35 to 45 decibels. And you can get even greater protection by wearing them in conjunction with a good pair of muff-style protectors.
