COMM 101 Video Five- Channel and Noise

by Adam Jenkins

📚 Main topics

ChannelThe channel is how a message travels from its source to its receiver. It includes the senses used to receive the message and any technology involved, such as phones and cell towers. 0:00
NoiseNoise is anything that interferes with communication or makes it ineffective. The four types discussed are physical, physiological, psychological, and semantic noise. 0:31
Physical noisePhysical noise occurs when the message, or part of it, fails to reach the receiver because the channel is blocked or disrupted, such as by a loud alarm or a cell phone dead spot. 1:01
Physiological noisePhysiological noise involves a bodily impairment or disability, such as blindness or hearing loss, that can make communication difficult. 2:03
Psychological noisePsychological noise occurs when someone is unwilling or unable to devote the necessary mental energy to communication. Distraction is one example. 2:33
Semantic noiseSemantic noise arises when people interpret the same word differently, so their intended meanings do not match. 3:35

✨ Key takeaways

Distinguish the noise typesPhysical noise disrupts the channel; physiological noise involves the body; psychological noise involves mental attention or energy; semantic noise involves differences in meaning. 1:01
Words can mean different things to different peopleEven when people speak the same language, a word such as “bottle” may bring different objects to mind. 4:06

🧠 Lessons learned

Pay attention to the communication processRecognizing what channel carries a message and what kind of noise may interfere can help explain why communication breaks down. 0:00
Check for shared meaningsPeople may assume they understand one another while attaching different meanings to the same words. 4:38

🏁 Conclusion/next steps

Consider possible barriersWhen communication is ineffective, consider whether the channel was disrupted, a physical or mental condition affected communication, attention was diverted, or the words were interpreted differently. 4:38

Transcript excerpt

0:00 our next smcr model element is the channel and the channel is important but pretty simple pretty straightforward the channel is just how is it that the message is getting from the source to the receiver so for example right now you're getting my message through your sense of hearing because i have a spoken part of my message you're getting it through your sense of sight because i've written part to the message anytime you're using technology to that's also part of the the channel so if you're making a phone call your phone's part of the channel the cell towers part of the

0:31 channel the other person's phone is part of the channel because it gets the message from the source to the receiver our last concept here at the smcr model stuff is this idea of noise and the way we use the word noise in this class it's a little bit different than the way you'd use the word noise in everyday conversation for our purposes noise is anything that causes the communication to go bad anything that causes us to have ineffective communication the good news is there's only four types of noise bad news is three of them start
