An earplug or shooting earplug is a device that is meant to be inserted in the wearer’s ear canal to protect the wearer from hearing loud noises, from gun noises to your snoring roommate. Earplugs can be either disposable or non-disposable, with foam and silicone ones generally being disposable or for use a relatively limited amount of times, while solid ones generally are regarded as non-disposable. Ear plugs are worn by industrial and construction workers who work within the hearing distance of loud machinery, and are used by militaries around the world during training and simulations. Since earplugs reduce the sound volume, earplugs are often used to help prevent hearing loss and tinnitus. Musicians who perform music styles for their loud nature, especially heavy metal music, often wear earplugs to prevent their own performances from damaging their hearing. Put in ear flights before your next trip, which helps reduce the air pressure changes generated by rapid altitude changes during takeoff and landing. Wearing earplugs anytime you’re exposed to noise above a level that allows normal conversation can help prevent long term loss of hearing. Situations where you should consider hearing protection include operating a lawn mower or other lawn and garden power equipment, attending a loud concert, and any occupational exposure that involves loud machinery.
