A speakerphone allows a user to communicate by voice with minimal physical operation requirements. This is a useful feature for people who have physical impairments. Note: although speakerphones offer significant amplification, users who are hard of hearing often do not find them suitable for use, possibly due to sound distortion and the clipping many speakerphones induce in order to solve the problem of bi-directional operation without feedback.
