Can art pave the way for a politically divided nation to move forward? Artist, cultural strategist and TED Fellow Marc Bamuthi Joseph reflects on the role of art, forgiveness and remembrance in the pursuit of public healing — especially...

We often use decibels, a measure of sound pressure, to describe how loud something is - but loudness is caused by how we perceive sounds, and the two often don't line up.

Microphones keep getting smaller and smaller, but have you ever asked what it would be like to have a bigger one in the form of a shirt? And though we tend to incorrectly think that we’re having two-way conversations with our pets, we...

Pupil outcome: I can explain how sound waves cause sounds to be heard, and describe the range and limits of human hearing. Key learning points: - Sound waves cause our eardrums, tiny bones within our ears, and the cochlea to vibrate. -...

The decibel is used to measure sound levels. It is represented by dB and is widely used in signals, communication, and electronics. The term decibel can be used to express an absolute value or a change in value (+1 dB or -1 dB). Decibels...

Different instruments can produce a wide variety of different sounds and notes, but why is this? Revealing how scientific principles combine to make music. Physics - Waves - Learning Points. Musical instruments are designed based on the...

In this fascinating video, Researcher Tim Holly uncovers the hidden world of mouse songs, revealing how the presence of a female mouse triggers high-pitched singing in male mice. By using specialized technology to make these ultrasonic...

This is a lecture video discussing the properties and uses of ultrasound. The video begins by explaining the frequency of sound waves detectable by the human ear, and how ultrasound waves operate beyond the human hearing range. The video...

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...

This video is a lesson about sound and how it works. It covers topics such as the definition of sound, how sound is produced through vibrations, the different types of waves (transverse and longitudinal), the speed of sound in different...
