Answer:
In order to have a successful lecture, we must be prepared for many possible problems. Some of the most common are:
- Uncomfortable temperatures in the room
- Poor acoustics in the room
- Dying microphones
- Disruptive sounds like coughing, sneezing, or ringing phones.
Before any lecture starts planning and preparation can help reduce these issues.
Heating and cooling are very important to the comfort of the lecturer and the audience. During the winter months it is important to have heaters ready to go. In addition, having extra space heaters is also helpful if some part of the room is colder than others. The same can be said for air conditioning in the summer. Having a fan with you can help cool you off or a personal portable air conditioner works well for small rooms.
