The Myth of Absolute Silence
Silence is often seen as a rare commodity in our fast-paced world. With noise pollution from traffic, construction, and even the hum of electronic devices, finding a quiet moment can be a challenge. Yet, even in the most silent places in the world, there is no such thing as absolute silence. This may come as a surprise, but the truth is that even in the quietest places, there is always some sound. In this article, we will explore why there is no such thing as absolute silence and what happens when we experience the quietest places in the world.
The Science Behind Sound
The concept of absolute silence may seem simple enough, but it is actually impossible to achieve. Sound is created when something vibrates, and the molecules in the air around that object vibrate in response, producing sound waves. Therefore, to achieve absolute silence, there would have to be no molecules present to vibrate. In other words, there would have to be a complete vacuum. Even in the most soundproof room, there will still be some air molecules present that will cause some level of sound.
The Quietest Place on Earth
The idea of absolute silence is not just a theoretical concept but can also be experienced in real life. For example, the anechoic chamber, located in Orfield Laboratories in Minneapolis, is known as the quietest place on earth. It is a soundproof room that absorbs almost all sound waves, making it so quiet that it can even cause hallucinations. However, even in this room, you can still hear sounds, and these sounds are not external sounds but internal ones.
Internal Sounds in a Quiet Environment
When you are in the quietest place on earth, your body’s internal sounds become much more noticeable. You may hear your heart beating or the sound of blood flowing in your veins. These sounds are always present in our bodies, but they are usually masked by external noises. In a quiet environment, these sounds become more prominent, and you become more aware of them.
Our Brains Generate Internal Noise
Moreover, our ears and brains are designed to perceive sound. Even if there is no external sound, our ears will pick up on any internal sounds that are present, such as the sound of our breathing or our heartbeat. In fact, even if we were to completely block out all sound, our brains would still generate some internal noise. This phenomenon is known as spontaneous neural activity, and it is the result of neurons firing in the brain.
Embracing the Beauty of Silence
The idea of absolute silence is an intriguing concept, but it is unattainable in the real world. Even in the quietest places on earth, there will always be some sound, and our bodies’ internal sounds become more noticeable. Silence, however, can still be a powerful experience. It allows us to disconnect from the outside world and focus on our internal world, leading to a sense of calm and inner peace. So the next time you find yourself in a quiet place, take a moment to appreciate the sounds of your own body and embrace the beauty of silence.

Book Recommendation
If you are interested in exploring the topic of silence and the sounds of the natural world, a book that I would highly recommend is “The Great Animal Orchestra” by Bernie Krause. In this book, Krause shares his experiences recording the sounds of the natural world and how these sounds can be an indicator of the health of our planet. The author’s background as a musician and sound ecologist offers a unique perspective on the importance of listening to the sounds of nature and the impact that human noise pollution is having on our environment. The book is both informative and inspiring, and it offers a deep insight into the power of sound in our lives.
Documentary/ Video
If you’re interested in exploring the topic of silence and the sounds of the natural world, I would recommend the documentary “In Pursuit of Silence.” This film takes viewers on a journey around the world to explore the impact of noise on our lives and the benefits of silence. The documentary highlights the work of artists, scientists, and activists who are advocating for the preservation of quiet spaces and the importance of listening to the sounds of nature.
