2. How is sound measured?

WebA sound wave is a pressure wave; regions of high (compressions) and low pressure (rarefactions) are established as the result of the vibrations of the sound source. These compressions and rarefactions result because sound a. is more dense than air and thus has more inertia, causing the bunching up of sound. Web8 de jul. de 2024 · The energy in a sound wave is measured in units called decibels. Amplitude refers to the force of a sound wave, and it is usually measured in dBA which implies decibels of sound pressure. Research has shown that the softest sound level that can be heard by humans is 0 dBA and a normal speaking voice is around 65 dBA.
