An ear trumpet is a historical device used to amplify sound for people with hearing loss. It is shaped like a cone or horn, with a wide opening to collect sound and a narrow end placed near the ear. Think of it as an old-fashioned, acoustic hearing aid. It gathers and focuses sound waves. Ear trumpets were common before the invention of electronic hearing aids. They are now mostly seen as historical artifacts. While simple, they provided a valuable service to those with impaired hearing.
