What is the type of audio monitor that is typically worn on the body during events?

The type of audio monitor typically worn on the body during events is known as an ear monitor. This device is designed to fit snugly into the ear, allowing the wearer, such as a performer or speaker, to hear audio cues, music, or other sound elements without being affected by ambient noise. Ear monitors provide a personalized audio experience while ensuring auditory clarity, which is essential in a live event setting where sound quality can significantly impact performance.

In live event settings, ear monitors are particularly advantageous because they help maintain audio balance without requiring loudspeakers that could create feedback or disturb the audience. This can enhance communication on stage between performers and help them stay in sync with organized sound elements.

The other choices describe alternative forms of audio equipment but do not specifically refer to the commonly used body-worn audio monitoring system. For instance, a headset monitor is indeed worn on the head and may have built-in microphones but does not fit the more specialized definition typically used in event planning for an in-ear monitoring system. Survey monitors and table monitors serve different purposes and are not worn, which further clarifies why ear monitors are the correct choice in the context of the question.
