UGC NET Questions (Paper – 1)

In communication theory, noise is a broad term covering anything that reduces the fidelity of the message as it moves from sender to receiver. This may include physical noise like loud sounds, technical noise like poor signal quality, or psychological noise like biases and preoccupations. Such interference can cause misinterpretation or loss of information. Recognizing noise helps communicators design strategies to minimize its impact.

Option A:
Option A treats any sound used to attract attention as noise, but such sounds can be part of deliberate communication rather than interference. Noise refers to unwanted factors, not purposeful signals.

Option B:
Option B correctly defines noise as any factor that distorts or interferes with accurate reception of the message. It includes physical, technical and psychological sources of interference and is the standard definition used in communication models.

Option C:
Option C is too narrow because it limits noise only to traffic sounds. While traffic is one example of physical noise, many other sources such as construction, classroom chatter or humming equipment can also interfere.

Option D:
Option D restricts noise to technical problems in electronic media, ignoring non technical and face to face situations. Physical and psychological factors can create noise even without any electronic devices.
