When announcing messages, why is it important to hold the microphone at a 45-degree angle?

Holding the microphone at a 45-degree angle is important primarily to avoid feedback and improve clarity. When a microphone is positioned too close to the speaker’s mouth or pointed directly at the speakers (especially in a loud environment), it can create a feedback loop—a loud screeching or whistling sound that occurs when amplified sound from speakers is picked up by the microphone and re-amplified. By angling the microphone, it reduces the chances of capturing this feedback while also allowing the speaker's voice to be clearly directed into the microphone. This positioning facilitates better sound quality and ensures that the audience receives clear and intelligible announcements.

Other considerations, such as making it easier for everyone to hear or making the speaker appear professional, are secondary to the fundamental purpose of sound clarity and avoiding feedback. While these attributes can enhance the experience, the primary reason for the 45-degree angle is to ensure clear audio transmission without interference.
