![]() ![]() When we talk about sound speed, we mean the speed at which sound waves travel in an elastic medium. The speed of sound varies with the medium through which it travels. It is defined as the dynamic propagation of waves through various mediums. As a result, the speed of sound is greatest in solids and lowest in gases. The greater the elasticity and the lower the mass, the greater the sound speed. Hence, the speed of sound defines how quickly it can propagate in some medium.The speed of sound in a given medium is determined by its elasticity and density. ![]() The term “speed of sound” refers to the velocity of sound waves in an elastic medium. ![]() The speed of sound is determined by the properties of the medium in which the transmission occurs. Sound wave propagation in a dynamic environment is known as the speed of sound. In the following section, we will learn how to calculate the speed of sound in various mediums. The distance travelled by any sound per unit of time is defined as the speed of sound. The velocity of the wave, also known as the speed, is the amount of distance travelled by a wave in one second in metres per second.Īs sound waves travel through a medium, they contract and expand the medium's parts. Each vibration of the vibrating body that produces the sound corresponds to a wave. It is the amount of time required to generate a single complete wave, or cycle. The time period is nearly inverse to the frequency. Sound frequency is measured in hertz (Hz) and is independent of the medium through which the sound travels. A low-frequency sound contains fewer waves than a high-frequency sound. ![]() The frequency of a sound is the number of sound waves produced per second. The amplitude is more precisely defined as the maximum displacement of the particles disturbed by a sound wave as it travels through a medium. Consider the height of the wave as opposed to its length. The amplitude of a given wave is its size. It is the distance between the centres of two consecutive rarefactions or compressions, or the combined length of a compression and the adjacent rarefaction. The wavelength is the distance that one wave travels before repeating itself. Sound is a longitudinal wave that experiences compressions and rarefactions as it travels through a medium. The wavelength is possibly the most important characteristic of sound waves. Sound waves have five main characteristics: wavelength, amplitude, frequency, time period, and velocity. Infrasonic sound refers to sound waves with frequencies less than 20 hertz. Ultrasound is defined as sound waves above 20 kHz that are inaudible to humans. These represent sound waves with wavelengths ranging from 17 metres (56 feet) to 1.7 centimetres in air at atmospheric pressure (0.67 in). Only acoustic waves with frequencies in the 20 Hz to 20 kHz range, known as the audio frequency range, elicit auditory perception in humans. It is the reception of such waves and their perception by the brain in human physiology and psychology. Sound is defined in Physics as a vibration that travels as an acoustic wave through a transmission medium such as a gas, liquid, or solid. While frequency refers to the number of vibrations produced by a single particle per unit of time, speed refers to the distance travelled by the disturbance per unit of time. The speed of sound in air, like the speed of any wave, refers to how quickly the disturbance is passed from particle to particle. As sound waves travel through a medium, they alternately contract and expand the parts of the medium through which they travel. When one particle is disturbed, it exerts a force on the next adjacent particle, causing that particle to be disturbed and the energy to be transported through the medium. A sound wave is a pressure disturbance that propagates through a medium via particle-to-particle interaction. ![]()
