Question

Is Sound louder in Hot or Cold air?

Answer 1

Hint: In physics, sound is a vibration that travels through a transmission media such as a gas, liquid, or solid as an acoustic wave. Sound is the receipt of such waves and the brain's perception of them in human physiology and psychology. Only acoustic waves with frequencies in the audio frequency range (about 20 Hz to 20 kHz) elicit an auditory perception in humans.

Complete answer:
Sound waves travel quicker in warm air and slower in cold air as a function of temperature. As a result, some portions of the wave will travel quicker than others as it travels through the atmosphere. If the air near the surface is colder than the air higher in the sky, the top of a sound wave will move quicker than the bottom, tilting and refracting the wave back toward the earth. Sound would leave an interstate or highway, travel up into the sky, and then be bent back down to the surface toward the colder air in this scenario. This implies that the sound will be stronger, and you will be able to hear the traffic noise from a greater distance.
It's quite hot on the surface during the day, so sound refracts the other way, up into the atmosphere and away from our ears. When a thunderstorm comes in on a hot summer day, the refraction sends the sound up away from you, so you don't hear it until it's nearly on top of you. When it's cold and the refraction is back down toward the surface at night, though, you may hear thunder from a great distance away. The wind's influence is more about sound distortion. As a sound wave travels through the air, it encounters wind, which causes certain components to accelerate and others to slow down. Because sound waves do not spread as a single wave on a windy day, they will be unclear when they reach your ear.

Note:
In chilly air, sound is amplified. This is because sound waves tend to refract more when the temperature drops, and they are generally refracted towards the earth. Furthermore, the sound's intensity will be increased. For example, when the direction of sound refraction changes at night as the temperature drops and the air becomes chilly, the sound will be louder. Furthermore, in cold air or cold weather, sound travels further.
