how headphones changed the world
To visit a modern office place is to walk into a room with a dozen songs playing simultaneously but to hear none of them. Up to half of younger workers listen to music on their headphones, and the vast majority thinks it makes us better at our jobs. In survey after survey, we report with confidence that music makes us happier, better at concentrating, and more productive.
Science says we're full of it. Listening to music hurts our ability to recall other stimuli, and any pop song -- loud or soft -- reduces overall performance for both extraverts and introverts. A Taiwanese study linked music with lyrics to lower scores on concentration tests for college students, and other research have shown music with words scrambles our brains' verbal-processing skills. "As silence had the best overall performance it would still be advisable that people work in silence," one report dryly concluded.
If headphones are so bad for productivity, why do so many people at work have headphones?
There is an economic answer: The United States has moved from a farming/manufacturing economy to a service economy, and more jobs "demand higher levels of concentration, reflection and creativity." This leads to a logistical answer: With 70 percent of office workers in cubicles or open work spaces, it's more important to create one's own cocoon of sound. That brings us to a psychological answer: There is evidence that music relaxes our muscles, improves our mood, and can even moderately reduce blood pressure, heart rate, and anxiety. What music steals in acute concentration, it returns to us in the form of good vibes.
That brings us finally to our final cultural answer: Headphones give us absolute control over our audio-environment, allowing us to privatize our public spaces. This is an important development for dense office
