What is the effect of temperature on velocity of sound?
Formula for speed of sound c = 331 + 0.6 × ϑ ϑ = temperature in degrees celsius. At ϑ = 20°C we get a speed of sound c = 331 + 0.6 × 20 = 343 m/s. 1 °C change of temperature is equal to 60 cm/s change of speed of sound. The speed of sound changes clearly with temperature, a little bit with humidity − but not with air pressure (atmospheric pressure). The words "sound pressure at sea level" are incorrect and misleading in the case of "speed of sound". The temperature indication, however, is absolutely necessary. The changing of atmospheric pressure does not change the sound of musical instruments in a concert hall or in a room. Look at link: "Temperature Dependence of Physical Entities".
What causes sound to change?
Sound can change due to variations in the frequency, amplitude, or quality of the sound waves. Factors like distance from the sound source, obstacles in the sound path, and environmental conditions can also affect how sound is perceived. Additionally, alterations in the medium through which sound travels, such as changes in temperature or pressure, can impact the speed and intensity of sound waves.
Is sound produced when there are increases in pressure or oscillations in pressure?
Yes, sound is produced when there are changes in pressure that cause the particles in a medium to oscillate. The pressure variations create sound waves that travel through the medium, such as air or water, and are detected by our ears as sound.
What would be an observable change in sound when the frequency changes?
An observable change in sound when the frequency changes is a difference in pitch. As the frequency increases, the pitch becomes higher, and as the frequency decreases, the pitch becomes lower. This change in pitch is due to the direct relationship between frequency and pitch in sound waves.
What does high pressure do to sound?
High pressure can increase the speed of sound transmission and alter the frequency of sound waves. It can also affect the way sound is perceived by the human ear, potentially causing discomfort or distortion in hearing.
What property of sound is affected by change in air temperature?
The speed, and therefore also the wavelength (for sound of a given frequency), are affected by temperature.
What is a property of sound that changes with frequency?
If you change sound's frequency and hold the velocity constant, the sound's wavelength also changes. If you change sound's frequency and keep the wavelength constant, then velocity also changes.
A medium can effect speed of sound by changes in what?
When you change density and temperature you effect the way sound travels through a medium.
How much does the velocity of sound changes for every 1 degree change in temperature?
0.61 meters a second
What would be the observable change in the sound when the frequency changes?

The velocity of sound in air is independent of change in what variable?
The velocity of sound in air is independent of changes in frequency. Sound waves travel at a constant speed determined by the properties of the medium they are traveling through, such as air temperature and pressure.
Explain why the speed of sound changes if the temperature of the medium changes?
The speed of sound depends upon elasticity and inertia of the medium which in turn depend upon the temperature of the medium.That's why speed of sound depends upon the temperature of the medium.
What property of a sound wave changes when a sound gets soft?
The amplitude of a sound wave is perceived as the sound's loudness.
When temperature increses the speed of sound changes?
Yes, it does.
Why does the speed of sound change if the temperature of the medium change?
The speed of sound is directly proportional to the temperature of the medium. This is because temperature affects the average speed of the molecules in the medium, which in turn affects how quickly sound waves can travel through it. As temperature increases, the speed of sound also increases due to the higher molecular activity.
What is a betacism?
A betacism is a sound change in which the B sound changes into a V sound.
