MSHA HEARING PROTECTOR LIST - July 2016

It is noted that the Environmental Protection Agency (EPA) has not updated its document for calculating the NRR Value to include the ANSI S-12.6-1984 standard data.Therefore, the majority of the values in this list reflect results obtained through the older ANSI S-3.19-1974 standard.

The NRR Value in this list may vary slightly from the manufacturer's value. If this occurs, the LARGER NRR Value should be used.

NOTE

Also, please note that the list contains some hearing protection devices that are no longer manufactured. However, because these devices may remain available to themining community through retail stores and other outlets, they are included in this list.

The Hearing Protector Factor List provides only an approximation of the dBA noise reduction offered by the hearing protector. Those hearing protectors which were testedaccording to the American National Standards Institute (ANSI) Test Method ANSI S-12.6-1984 are designated by (XX) after the model: Hearing protectors tested accordingto the early ANSI S-3.19-1974 method are designated by (X), while hearing protectors tested according to the oldest method, ANSI Z24.22-1957, are unmarked. The testingprocedures differ among the three methods and the results for a given hearing protector may vary. Because of this, a comparison of the factor for a hearing protector testedunder the 1957 method should not be made with factors obtained under the 1974 and 1984 methods.
