Scientifically, the sun is incredibly loud—if sound could travel through the vacuum of space, it would be a deafening 100 decibels on Earth, which is roughly the volume of a jackhammer or a loud rock concert. The sun is a massive ball of nuclear fusion and turbulent plasma; these constant "storms" create sound waves of immense power. However, because space is a vacuum, there are no air molecules to vibrate and carry these waves to our ears. If the atmosphere extended all the way to the sun, the roar would be constant and potentially life-threatening to our hearing. Researchers at NASA use "helioseismology" to capture these vibrations and translate them into frequencies that humans can hear, resulting in a low, rhythmic "thrumming" or "humming" sound. So, while the sun is "silently" shining from our perspective, it is actually a roaring engine of energy that would drown out every other sound on our planet if physics allowed it to reach us.
