What are some sources of noise that interferes with communication during a class lecture?
There are two types of noises that can interfere with communication during a class lecture. These noises can be classed as internal and external interference and communication barriers.
Internal Noise: mental distractions that a person can have thinking about other things that have nothing to do with the class lecture. Such as:
"What should I cook for dinner tonight?" or"I don’t think I passed my last exam."
When a person is not mentally focused on the sender’s message because of mental distractions from other matters, the receiver can lose a lot of the communication. This can definitely frustrate barriers to communication of the message.
- External Noise: noise distractions that can come from external sources such as other students having personal conversations during the lecture, especially in large university lecture halls.
Technology can also be an external noise distraction (and an internal one if it distracts your thoughts) because just everyone has a cell phone. Unless the instructor has specific instructions that cell phones are not allowed in the class lecture, students can easily be distracted by other students' reading their social media and abruptly laughing out loud or by constant alerts coming through various phone chimes or vibrating sounds.
My pet peeve was the leaf blowers outside the classroom window.
