Why does the speed of sound vary with altitude?
The speed of sound, which is influenced by the temperature and altitude, can vary under normal atmospheric conditions. This variation occurs because the medium through which sound waves travel does not always respond adiabatically and the speed of sound can also be influenced by its frequency. It is important to consider the limitations of the concept of speed of sound when extreme attenuation is involved.
Does noise increase with speed?
Many people initially believe that the noise from a vehicle increases with its speed. However, researchers have gone beyond this intuition and conducted studies to measure this phenomenon. It has been found that a 10 km/h increase in speed within a distance of 7.5 m leads to a measurable increase in noise level.
Is the noise more pronounced during cold weather?
Due to the difference in speed of sound between warm and cold air, sound waves tend to deflect away from warm air and towards the ground. Consequently, this phenomenon enables sound to travel greater distances in cold weather. However, it is worth noting that various factors contribute to the quietness of winter mornings beyond the influence of sound velocity.

Does sound travel further in cold weather than warm?
Is it true that sound travels further in cold weather than in warm weather? The answer is yes, and this can be explained by the fact that the speed of sound is slower at colder temperatures. The phenomenon is related to the vibration of molecules, which occurs at a slower pace in lower temperatures.
As a result, when sound encounters cold air, it moves at a reduced speed, allowing it to travel further. This difference in speed can affect how sound is perceived, leading to variations in the way it sounds in different temperatures.
So, to summarize, in cold weather, sound travels farther due to the slower vibration of molecules caused by the lower temperature.
Why is sound so quiet in winter?
The reason sound can travel farther in cold weather is due to the speed of sound being faster in warmer air compared to colder air. This causes the sound wave to bend away from the warmer air and back towards the ground. However, it is important to note that the quietness of winter mornings is influenced by various other factors, not just the speed of sound.
As a result, the sound wave bends away from the warm air and back towards the ground, allowing sound to travel a greater distance. Nevertheless, it is crucial to recognize that the tranquility experienced on winter mornings is impacted by numerous additional elements aside from the speed of sound.
