WebSound waves are longitudinal waves that must pass through a medium, such as air. Echoes are reflections of sounds. The frequency of ultrasound is above 20 kHz. … 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.

In human physiology and … WebSound waves can be measured according to several different paradigms: amplitude, wavelength, frequency, speed, and, at times, phase. Each of these is associated with certain characteristics, such as loudness and pitch with amplitude; rarefactions and compressions with frequency; distance with wavelength; and elasticity and inertia with speed.

WebThe hertz (symbol: Hz) is the unit of frequency in the International System of Units (SI), equivalent to one event (or cycle) per second. The hertz is an SI derived unit whose expression in terms of SI base units is s −1, meaning that one hertz is the reciprocal of one second. It is named after Heinrich Rudolf Hertz (1857–1894), the first person to provide … Web14 de abr. de 2024 · The intensity of sound is measured in decibels (dB), and exposure to sounds at or above 85 dB can cause hearing damage if exposure is prolonged or repeated. For example, a rock concert or music played through headphones at a high volume can reach levels of 100 dB or more, which can cause damage to the hair cells in the inner ear.
