12 Σεπ 2023 · In this post, we’ve taken a comprehensive look at sound waves, starting with the basics of what type of wave sound is—a longitudinal wave. We discussed its key aspects like frequency, amplitude, and speed in various media, breaking down how these properties shape our auditory experiences.

large amplitude sound waves are loud; reflected sound is called an echo; the range of human hearing is 20 Hz to 20 000 Hz; sound waves with a frequency above 20 000 Hz are called...
An audio wave is the vibration of air molecules, which is how sound travels. A waveform describes a wave by graphing how an air molecule is displaced, over time. Amplitude is the strength of a wave's effect; the higher the amplitude, the more the air molecules are displaced.
21 Σεπ 2019 · What are Sound Waves? As you just learned, you hear when your ears process sound waves produced by an object. The object produces waves by vibrating. When an object vibrates, it pushes against the surrounding air. The vibrations cause the air to expand (called rarefaction) and compress.
