Programmers, or so to speak all IT professionals, put in their best efforts to make computing, browsing, maintenance and record keeping easier for millions of computer users. Since programming requires focus, mental dexterity and a problem-solving mind-set, we see programmers and other computer professionals employing different means to be at their creative best. One of those ways is to use headphones at work. It helps them to be in their creative zone; and as they shut down all external audio stimuli with people around them, it helps them focus better on their work.
As we know that programming involves designing, writing, testing, debugging and maintaining source code of computer programs by using programming languages like C++, C#, Python, Smalltalk, Java, etc, programmers are supposed to have knowledge of the application domain, specialized algorithms and formal logic, and are supposed not to commit mistakes. Therefore, to eliminate any probable chances of any error, they use headphones, which act as a Do Not Disturb sign. Wearing headphones is a signal that you don’t want to be disturbed, whether you are in the mood of music or you do so just to avoid flyers from people around you.
During their occasional or frequent jaunts in trains or planes when it gets too noisy out there, headphones can help programmers limit their sensory input from the outside world and minimize distractions.
