Noise as interference – UGC NET Question

Noise is any unwanted interference that distorts or obscures the message as it travels through the channel. Static in a microphone changes or masks parts of the teacher's voice. This makes it harder for students to understand,so it clearly functions as noise. The concept comes directly from engineering models like Shannon's.

Option A:
Channel refers to the medium of transmission,such as air or electronic signals,not the distortion.

Option B:
Feedback is the receiver's response,which is purposeful and not random interference.

Option C:
Noise is the interference (static/distortion) that reduces message clarity,so microphone static is noise.

Option D:
Redundancy means deliberate repetition of message elements to improve clarity,rather than accidental distortion.
