The term "ear trumpet" is an older term that was used to refer to a simple device that people with hearing difficulties would use to amplify sounds. This device has been replaced by more modern hearing aids, which are smaller, more discreet, and more effective. However, there are still several synonyms that can be used to describe an ear trumpet. Some of these include "hearing horn," "auditory horn," "listening cone," and "sound funnel." Each of these terms can be used to describe a device that is designed to help people hear sounds more clearly and louder than they would otherwise.
