This video covers: - How sound waves travel through materials - The idea that sound waves are longitudinal - How wavelength changes with speed - The structure of the human ear and how it works - How the range of human hearing changes...

Space is full of radio waves, plasma waves, magnetic waves, gravitational waves, and shock waves, all of which can travel in space without a medium. These waves are recorded by instruments that can sense these waves, and the data is...

This video breaks down the complex mechanics of sound and how sound travels. Students learn about vibration and sound waves, and even get to test their own instruments!

Have you ever put a seashell up to your ear and heard a roaring sound the sounds sort of like the ocean? Is it magic? No! It's science! Jessi and Squeaks explain what's up!

Squeaks is heading on a trip around the world! He's going to hear so many cool sounds, and wants Jessi to experience them, too. In this episode, he learns about how humans (and a couple of other animal guests) hear.

The ability to recognize sounds and identify their location is possible thanks to the auditory system. That's comprised of two main parts: the ear, and the brain. The ear's task is to convert sound energy into neural signals; the brain's...

We learn a lot about our surroundings thanks to sound. But... what is it exactly? Sound, that is. What is sound? And how does it travel? And what is this Doppler Effect that we've heard so much about? In this episode of Crash Course...

After a concert, you find it difficult to hear your friend rave about the show. It sounds like they're speaking from across the room, and it's tough to make out their voice over the ringing in your ears. But, by the next morning, the...

Learn all about how sound works with Jessi and Squeaks on SciShow Kids!

Movies take a lot of dramatic license where science is concerned, but who's getting it all wrong on the silver screen. From the g-force you would suffer when achieving lightspeed to what a nuclear bomb would sound like in space we...

This video is a detailed explanation of how our eyes and ears work, focusing on the process of vision and hearing. It discusses the different parts of the eye and their functions, such as the cornea, iris, lens, and retina. It also...

This video explains the basics of sound and how it is produced, transmitted, and perceived. Explore the physics of sound and acoustics. Acoustics is the study of mechanical waves and how they move through gas, liquids, and solids....

DIY SCI host Steve Spangler demonstrates how you can use a can and string to make some weird sounds and even talk to people!

This video explains how sound waves travel through the air, solids, and liquids to reach our ears. It explores how vibrations create sound waves, which are collected by our ears and make our eardrums vibrate. Our brain recognizes these...

Tamal Ray, anaesthetist and baker, Professor Charles Spence, experimental psychologist at the University of Oxford and chef Jozef Youssef embark on a journey to decode the science of flavour. Professor Spence and Jozef challenge Tamal to...

This video has kids practice first tapping out sounds to a short vowel word with blends. Then, they map it or turn the sounds into letters, and finally they spell the word. This is great practice for beginning readers and writers and...

Experts in neuroscience help us understand why the human brain is a marvel of structure and function. This video looks at how the nervous system allows our five senses to opperate, it looks at the specific processes which allow us to...

Learn Sound and Light for Kids | Round-Up Lesson | Kids Academy If you want to learn sound and light then you are at the right place as we will guide you through it all. Sound: The sound is a type of energy that is produced when...

Mr. Andersen explains how sound waves are created and perceived. A brief discussion of pitch and loudness are included. A generated sound of varying pitches is also included.

In this video Paul Andersen compares and contrasts mechanical and electromagnetic waves. Both types of waves transfer energy through oscillations but mechanical waves requires a medium. Several examples of each type of wave are included.

Have you ever wondered how your ears work? In this delightful and fascinating talk, biophysicist Jim Hudspeth demonstrates the wonderfully simple yet astonishingly powerful mechanics of hair cells, the microscopic powerhouses that make...
