Lecture rooms can get very noisy regardless of where you're sitting. This makes it difficult to understand the professor at times. Since the majority of professors are already connected to mics if there is a way to listen to the professor with a live streaming audio website or radio program this can allow students to listen with headphones for clearer understanding from their computers or phones. This may prove to be an effective addition to the teaching experience. A room password or local area network could be used to prevent people from viewing from home or other location.
