In environments with extremely high noise levels, workers can use double protection, such as earplugs under the earmuffs, which include wireless technology. There are many types of assistive devices available to help people with hearing loss. These devices can amplify sounds, provide alerts, and help you communicate with other people. For example, alert systems work with doorbells, smoke detectors and alarm clocks to send visual signals or vibrations.
Devices that use keyboards, touchscreens, or text-to-speech technology can help you give and receive information more effectively. Learn more about the wide range of assistive devices available for people with hearing loss at the National Institute on Deafness and Other Communication Disorders. Custom earplugs are custom-made earplugs that are designed to fit the shape of the ear canal. Because of their shape, many people find them easier to insert and use for long periods of time.
