To prevent noise-induced hearing loss, electronic hearing protection devices are used to reduce the strength of surrounding noise and enhance the lower sounds.

Electronic hearing protection devices are primarily designed to protect the inner ear from direct loud noise exposure. Most electronic hearing protection devices merely cover the outer ear region with the device's ear plugs or cushions, and provide a seal for the outer ear with the device's cushion or liners. In normal settings, the wearer can maintain complete reception of external noises. Electronic hearing protection devices may be essential for persons who have severe allergies to noise or dust.The devices are available to people over the age of eighteen, with the most prevalent versions being "over-the-counter" devices that can be purchased without a doctor's prescription and the more advanced "intra-oral" devices that are delivered by specially trained health care professionals.

Sounds-induced hearing loss affects people because their ears become overly sensitive to outside noise or their surroundings. It can occur in any part of the hearing pathway, including the inner ear, middle ear, outer ear, or brain. A build-up of wax in the auditory canal is one of the reasons of this disorder. If left untreated, it might result in permanent damage and/or hearing loss. When exposed to loud noises for an extended period of time, one of the first steps in coping with this is to wear suitable safety equipment, such as earplugs and other Noise Reduction Devices.For instance, in September 2020, the advanced communication solutions developing company, Cardo Crew, launched Mesh Communication Technology for PPE makers and the construction workers in the U.K. to avoid the occurrence of hearing problems.

Earmuffs and earplugs are some of the electronic hearing protection devices used today. These are custom-made earpieces with cushions inside to keep the ear canal free from wax and dirt. They can either be worn in the ears or else be worn over the ears. They are perfect for individuals working in industrial or manufacturing environments where noise can be loud and constant. Earmuffs are perfect for railroad workers who need to keep their ears protected from the grinding noise of the wheels on the train tracks, as well as those in aviation who have to wear protective devices while in flight.
