Guys, we all feel that the voice is more powerful or we can say more hearable in winter or cold days but question is “WHY?”
In the cold winter morning, the world is breathing breath, and it seems that you can hear the pin drop from five blocks. When you did not actually hear that distant pins, you would have had a better chance in those cool temps. Because the sound in the hot atmosphere travels fast, it moves in cold climates. Let us explain.
People constantly talk about the speed of sound, but it actually varies depending on its atmosphere. The reason for this is that the sound is a wave of pressure that depends on the surrounding molecules to get where it goes and it can be fast or slow depending on the molecule. It travels faster than water in the air, for example, and travels faster than wood in water. When it comes to air, both humidity and temperature play a role in sound movement. Humility decreases air density (moist air feels heavy!), Which makes it travel a little bit faster. The heat converts air molecules into speed, so they are ready to push the pressure wavelengths at slow motion molecule. Because of that, heat travel too fast.
You probably feel like a straw in a glass of water, it seems to be broken in half. It is due to the origin of light: when it goes through the medium like water in the air, the rays of light rays. In particular, the speed of light slows down in water, which turns it towards the air-water boundaries (try it if you do not believe me!). When the wave reverses, moving from slow to medium, it moves away from the boundary.
In colder days, there is a hot air level on the cold pockets near the ground. When you shout to a friend on the street or listen to your bus (ultimately!), The sound direction that normally exits all directions is ignored by the hot air. Because the noise from the warm air increases rapidly in the air, the wave turns back to the hot air and to the ground. As such, the sound is capable of proceeding in cold climates.
There is a lot more that is quiet on the winter morning only than the sound speed. Snow absorbs the noise, so you can hear the tiny noise you hear from the ground in general. Many people like to stay in cold weather, either, there are fewer cars, pedestrians and animals to make furry. You can feel sad in the cold, but at least you have peace and tranquility as your reward.
