Hearing Protector Device Compendium


Hearing Protector Devices

The Hearing Protector Device Compendium is a comprehensive searchable database of hearing protection devices. This web tool was created by the National Institute for Occupational Safety and Health to help workers and safety professionals select the most appropriate product for their unique environment. The tool identifies hearing protector devices by type, manufacturer, and noise exposure level. It also explains essential product features, including desired noise reduction ratings, mean attenuations, standard deviations of attenuations, protector construction and materials, and other features that can aid the selection of protectors for specific situations.

Many companies that were listed in the previous compendium have merged with other companies or have ceased to manufacturer or sell hearing protectors. In the pursuit of completeness all other manufacturers are invited to submit their data.
