Which example demonstrates internal noise during communication?

Internal noise in communication refers to psychological barriers or impairments that affect the clarity and effectiveness of a message. This can include distractions that are mental or psychological rather than physical. The choice of long meetings without snacks or breaks exemplifies internal noise because it can lead to decreased focus and cognitive fatigue among participants. When individuals are hungry or fatigued, their ability to engage attentively with the material being presented diminishes, creating an internal barrier to effective communication. This kind of noise originates from within the individuals involved in the communication process, impacting their interpretation and response to the message being conveyed.

In contrast, the other examples provided relate more to external distractions. For instance, loud environments or visual distractions constitute external noise, as they involve physical interruptions to the communication process rather than psychological ones. Similarly, people talking over each other is also an external issue affecting the flow of communication rather than internal mental processes impacting message reception.
