Final answer:
The lapel microphone is typically used in television news and interview programs for its discretion and consistent audio capture while allowing hands-free operation.
Step-by-step explanation:
In television news and interview programs where participants are seated, the microphone of choice is usually the lapel microphone. These microphones are also known as body microphones or wireless microphones. Unlike hand-held microphones that are preferred by singers for their minimal alteration to sound, lapel mics offer discretion and convenience in a seated setting.
They are small devices, typically clipped to the clothing, allowing for hands-free operation and ensuring that the microphone is consistently placed close to the mouth for clear audio capture. These wireless devices operate on a radio system and are managed by the sound board, meaning they can be turned on or off as needed during the production. Although they are generally reliable, it's important for the sound team to secure them properly to avoid any odd sounds or background noise interference.
