Finding Silence in a Noisy World

Recently, I experienced an unexpected moment of embarrassment. While walking my dog through my quiet Brooklyn neighborhood at twilight, I suddenly became aware of a sound I had never noticed before: the chirping of crickets. This realization dawned upon me because it was the first time I had walked through the area without my AirPods plugged into my ears.
Earlier this year, I made a startling revelation: I had been listening to too many podcasts, a habit that began as a distraction during lengthy subway rides, slowly morphing into an obsession over the pandemic. Soon, my quiet moments were crowded with the voices of others, and I realized I could no longer think my own thoughts—even in silence. Determined to reclaim my mental space, I decided to quit podcasts for a month.
The Transformative Power of Quitting
Quitting something you enjoy can dramatically alter your worldview, and in my case, it transformed my mental landscape. As weeks passed without podcasts, I noticed a renewed order in my thoughts. The absence of auditory distraction allowed me to concentrate on singular ideas; my attention span improved, I read more books, and even started to smile and interact more with my neighbors. Most importantly, I began to notice the crickets.
You might attribute my newfound mindfulness to a placebo effect—after all, once I decided to be more present, I indeed became so. But upon consulting psychologists and neuroscientists, I learned about the brain’s default mode network, which governs thought processes, perception, and executive function. By eliminating a continuous stream of external stimuli, I freed up cognitive bandwidth, making it easier to narrate my own life story.
The Cognitive Costs of Multitasking
- The human brain is incapable of true multitasking; what feels like multitasking is actually rapid task-switching, which has a cognitive cost.
- Silence activates the brain’s default mode, promoting self-reflection, planning, and daydreaming.
- Engaging in simple sensory experiences, like walking outside without headphones, can restore cognitive resources better than consuming media.
The idea that listening to podcasts while engaging in other tasks equates to multitasking came as a realization. Earl Miller, a professor of neuroscience at MIT, explained that our brains switch tasks rapidly, a process that incurs cognitive costs. Modern society is filled with distractions; smartphones and endless apps coerce us into splitting our attention, leading to diminished capacity to engage with the real world.
Evolution Meets Modern Distraction
Reflecting on my own life, I can’t solely blame smartphones. My distraction habits trace back to the ‘90s, when I found solace in my trusty Walkman, listening to mixtapes while working at my family’s restaurant. Fast forward to college in the early 2000s, and my first iPod brought more distractions with 10,000 songs at my fingertips. Over the years, this has escalated to the omnipresence of podcasts and other media filling my free moments.
Between 2015 and 2025, podcast listening in America surged by 355%. A substantial fraction of listeners devote over 10 hours each week to this medium. As journalist Sirena Bergman noted, dedicating 35 hours to podcasts raises important questions about their impact on our brains. The absence of silence—an essential backdrop for self-reflection and mental recovery—can lead to cognitive depletion.
The Science of Silence
Scientific research reinforces this notion. In a study published in 2005, medical researcher Luciano Bernardi found that silence led to physiological relaxation, lowering blood pressure and heart rates. Further studies indicate that silence facilitates neurogenesis; in one study, mice exposed to silence developed functioning neurons, unlike those subjected to sound.
Moreover, silence encourages internal dialogue—self-reflection happens most when our minds are free from external narratives. Dr. Marcus Raichle’s research into the brain’s default mode network revealed that the mind is most active while at rest, enabling self-reflection and creative thinking. During my podcast-less month, I could finally tune into the world around me, hearing birds sing and leaves rustle while contemplating my day.
The Importance of Breaks
Experiencing boredom, though initially uncomfortable, proved beneficial. While I missed the distraction of podcasts, I also discovered that silence could be a powerful form of relaxation. My daily tasks felt less burdensome; however, I recognized the cognitive struggle inherent in multitasking. It was increasingly clear that my attempts to listen to informative podcasts while engaged with mundane chores led to missing crucial information.
Human evolution has tailored our brains to focus intently on limited tasks rather than juggling multiple stimuli. As Miller articulated, our past equipped us for simpler environments; living in today’s fast-paced, information-saturated world overwhelms our cognitive abilities.
Finding Balance in Modern Life
While it is challenging to limit multitasking in the 21st century, I have learned the value of pausing to reconnect with the world around me. This practice enhances productivity and well-being. When faced with mental blocks, I now understand the importance of stepping away from screens entirely—embracing nature, engaging my senses, and allowing my thoughts to wander.
In reflecting on my journey, I now feel a newfound appreciation for quiet moments. Instead of constantly seeking distractions, I have begun to savor the sounds around me—finding joy in the rustling grass and the comforting song of crickets. The sweet sound of silence has transformed my daily experiences.
