Hearing Protector Device Compendium

The NIOSH Hearing Protector Device (HPD) Compendium is no longer available. The NIOSH HPD Compendium represented an effort to collect data published by manufacturers of hearing protectors sold in the United States. It was a comprehensive searchable database of hearing protection devices to help workers and safety professionals select the most appropriate product for their unique environment. Many companies that were listed in the previous NIOSH HPD Compendium have merged with other companies or have ceased to manufacture or sell hearing protectors. Many manufacturers have their own websites which help the consumer choose what would be the best protection for themselves or their employees. Company websites are updated with new products as they become available and old products deleted when removed. Visit the manufacturer of your choice to find information on appropriate hearing protection.
