Final answer:
No, it is inappropriate to talk on a cell phone during a presentation, even in a whisper, as it is disrespectful and can be a distraction to others.
Step-by-step explanation:
It is generally considered to be disrespectful and inappropriate to talk on a cell phone while attending a presentation, even if you are whispering. The emergence of mobile phones has necessitated the development of new social norms and behaviors. In public settings, including presentations and performances, attendees are expected to pay attention and show respect to others by minimizing distractions. Texting, a technology that enables silent communication, is a more acceptable alternative in situations where urgent communication is necessary. In academic settings, students are encouraged to focus on class activities and put their phones away to avoid multitasking, which studies have shown to harm academic performance. Furthermore, the expectation of turning off cell phones is a common practice out of courtesy in various social situations, such as during theater performances, evidenced by the polite reminder from the onstage actors.
