Have you ever thought about how sound travels? I remember being mesmerized by the “telephone can” I made as a child, the string connecting my voice to my friend’s ear seeming like magic. But as I learned more, I realized that sound, unlike my wanderlust, can’t travel everywhere. It needs a medium, and there are places, or rather, states of being, where sound simply can’t exist.
The Silent Vacuum and Beyond
Sound travels through the vibration of particles. Imagine dropping a pebble in a pond – the ripples are like sound waves, spreading outwards. Just as those ripples need water, sound waves need a medium like air, water, or even solids like walls to propagate.
So, What Can Sound Not Travel Through?
The Void of Space
The most well-known answer is a vacuum, like the vast expanse of outer space. Astronauts might witness breathtaking explosions of light from distant stars, but they wouldn’t hear a thing. Why? Because space is largely a vacuum, devoid of the matter that sound waves need to travel.
“Imagine standing on the moon,” says Dr. Emily Carter, author of “The Soundscape of the Universe,” “You could see the Earth, a vibrant blue and green oasis, but utter silence would envelop you.”
Perfect Vacuums on Earth?
Creating a perfect vacuum on Earth is a challenge, but we get close. Specialized chambers used in scientific research, for example, can achieve near-perfect vacuums.
Other States of Matter
While sound travels effectively through solids and liquids, certain states of matter, like extremely hot plasma, can disrupt sound waves due to their high energy and chaotic particle movement.

Exploring the Sounds (and Silences) of Our World
Understanding where sound can’t travel highlights just how precious the symphony of our planet is. From the crashing waves of the Pacific Ocean to the rustling leaves in Kyoto’s Sagano Bamboo Forest, our world is a tapestry of sound.

Sound and Travel: FAQs
Can sound travel through water?
Yes, sound travels faster and further in water than in air. That’s why whales can communicate across vast distances in the ocean.
Is sound affected by altitude?
Yes, sound travels slower at higher altitudes because the air is less dense.
Why is it so quiet after a snowfall?
Freshly fallen snow absorbs sound waves, creating a unique sense of stillness.
