This video explains how microphones and speakers work by using electromagnetic induction and motor effects, respectively. The video goes on to describe the inner workings of a microphone, which includes a conducting coil attached to a...

Professor Geraint Lewis, astrophysicist at University of Sydney, takes up the challenge to explain a proposed theory of everything in the time it takes to ride an elevator from ground floor to penthouse.

Almost every second of the day you are surrounded by sounds. Through easy-to-understand examples, this program helps students grasp how sounds are formed andhow sound travels. Special attention is given to the different characteristics...

In this video, we explore the first part of the pathway of audition (hearing). We will trace the movement of a sound wave from the outside environment through the ear canal and up to the oval window.

In this live-action program viewers will learn that the larynx is an organ in the neck. It is crucial for speech and breathing. Students will come to understand the larynx controls airflow during breathing, protects the airway during...

Headphones work by converting electrical signals into sound waves through the use of an electromagnet and a cone. The diaphragm cone inside the driver assembly vibrates when triggered by an alternating current, creating sound waves that...

Thomas Edison, the man who invented the light bulb, also came up with the basic idea for how to record sound. He attached a needle to the diaphragm of a telephone receiver, which etched sound vibrations onto a quickly moving paper. This...

Can you change vibration speed? #VeritasiumContest

In this Nature League Field Trip, Brit sits down with Dr. Laurie Slovarp to explore the ways that humans and non-human animals make sounds. A special thanks to Dr. Slovarp for collaborating on this Nature League Field Trip.

In this video, I talk about how hearing takes place, starting with the soundwaves entering the ear, hitting the eardrum, and being transfered to the internal ear. Enjoy the process. I hope you can hear it :)

In this video, I show how Sound is accurately transferred to the inner ear. Since there is fluid inside the cochlea, impedance matching needs to take place. It happens due to the 1.3 to 1 ratio of movement between the maleus, incus and...

In this video, I talk about how the brain processes information on the different pitches that we hear. I'm warning you - it starts off a little scary, but by the end of the video, you will have a good idea of how we hear different...

In this video, I talk about the organ of corti, which is found on top of the basiliar membrane inside the cochlea. When the basilar membrane vibrates up and down, that causes the organ of Corti to move up and down, and the tectorial...

In this video, I show the details of how the bending of the stereocilia on the inner hair cells results in the release of neurotransmitters, which ultimately results in hearing. Enjoy.

Waves transfer energy from one place to another. You should already know how to describe them in terms of frequency, wavelength and amplitude In this video we’re going to look at the two ways they can be classified. Waves are produced as...

Explore the fascinating function of whiskers in animals. We will learn how whiskers aid vision, serving as touch receptors, and providing a heightened sense of feeling. The whiskers play a crucial role in helping animals navigate their...

This video explains how sound waves can be displayed on an oscilloscope and how the amplitude and frequency of the waveform relate to the loudness and pitch of the sound. The video uses examples of different sound waves and the...

This live-action video program is about the word Sound Energy. The program is designed to reinforce and support a student's comprehension and retention of the word Sound Energy through use of video footage, photographs, diagrams and...

Use physics to create cool patterns on a vibrating plate. How is this like a guitar string or a singing wine glass?

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....

This lecture video explains how sound waves propagate, transfer from air to a solid, and how the human ear works. The video then explains how sound waves interact with solids, including reflection, absorption, and transmission. The video...

It explains the characteristics of sound, namely amplitude, time period and frequency of a vibration. It talks about loudness, pitch and quality of sound.
