In some occasions that require high concentration and quietness, such as exams, meetings or psychological counseling, mobile phone jammers can effectively eliminate the interference caused by mobile phones and help attendees or participants stay focused. By creating a "mobile phone-free" environment, people can better devote themselves to the current task, reduce anxiety and distraction, and thus improve their emotional state.
