Hi there! I'm Dr. Emily Carter, and I'm a marine biologist with over 20 years of experience studying the ocean and its inhabitants. My research has taken me all over the world, from the coral reefs of Australia to the deep sea trenches of the Pacific. I'm passionate about understanding how marine animals use sound to communicate and navigate in their underwater world, and I'm particularly interested in the impact of human-made noise on marine life.
Let's dive into your question: Can humans hear sound underwater?
The short answer is yes, but it's a bit more complicated than that.
You see, our ears are designed to work in air, not water. When we're on land, sound waves travel through the air and enter our ear canal, causing the eardrum to vibrate. These vibrations are then passed along to the tiny bones in the middle ear – the malleus, incus, and stapes – which amplify the sound and transmit it to the inner ear. The inner ear contains the cochlea, a fluid-filled structure that converts the vibrations into electrical signals that our brain interprets as sound.
Underwater, things work a bit differently. Water is much denser than air, meaning sound waves travel about four times faster through water than they do through air. This difference in density also affects how sound waves interact with our ears. When our head is submerged in water, the sound waves don't pass through the ear canal and vibrate the eardrum as efficiently. Instead, much of the sound energy is transmitted to our skull bones, which then vibrate and transmit the sound to the inner ear.
However, this bone conduction method of hearing underwater is not as effective as our normal hearing in air. We lose a lot of the higher frequencies, making it difficult to understand speech and distinguish between different sounds. Imagine trying to have a conversation in a crowded room with your fingers plugged in your ears – you can still hear something, but it's muffled and unclear. That's kind of what it's like trying to hear underwater.
There are ways to improve our underwater hearing, of course. Divers often wear specialized equipment, like full-face diving masks or underwater communication systems, which create an air space around the ears and transmit sound more effectively. These devices allow divers to communicate with each other and hear important sounds underwater.
Furthermore, some evidence suggests that with training and experience, humans can learn to interpret sounds underwater more effectively. Experienced divers and swimmers, for instance, can often identify the direction and distance of sounds underwater better than someone who's just dipped their toes in the water. This adaptation might be due to the brain learning to better process the sounds transmitted through bone conduction.
In conclusion, while humans can technically hear underwater, our hearing is significantly less effective than it is in air. The denser medium of water, the loss of high frequencies, and the reliance on bone conduction all contribute to a muffled and less clear soundscape underwater. However, with the help of technology or training, we can improve our ability to perceive and interpret the fascinating world of sound beneath the waves.

On land, sound travels through air conduction. This means that sound waves travel through the air, causing your eardrum to vibrate. ... Researchers have determined that bone conduction allows us to hear sounds underwater that are much higher in pitch than sounds we hear on land.
