Sound waves are longitudinal waves that travel through a medium like air or water. When we think about sound, we often think about how loud it is (amplitude, or intensity) and its pitch (frequency).

2023年7月23日 · Sound Waves: A great collection of interactive science lessons from the University of Salford, which explains what sound waves are and the different ways in which they behave.

In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. [1]

2024年12月13日 · The study of sound should begin with the properties of sound waves. There are two basic types of wave, transverse and longitudinal, differentiated by the way in which the wave is propagated.

2023年11月8日 · Sound waves are fundamentally pressure waves, traveling through the compression and rarefaction of particles within a medium. Sound waves consist of areas where particles are bunched together, followed by areas where they're spread apart.

2021年7月27日 · Sound waves are a type of energy that’s released when an object vibrates. Those acoustic waves travel from their source through air or another medium, and when they …

2025年1月8日 · Explore the science of sound, from how sound waves travel to their applications in music, medicine, and technology. Discover the principles of acoustics and how sound impacts our daily lives.

We don't pay much attention to sound, but it's everywhere and affects our daily lives. How do sound waves work and how do we use them? Click here to learn more.

2019年9月12日 · Find out more about studying sound under water and read about what is needed for sound to be heard, and how sound travels through water to understand some of the key science concepts.

Sound waves are produced by all vibrating objects. Loudspeakers work by converting electrical energy into kinetic energy. This vibrates the cone which creates the sound waves.
