The side of the house is 0/000 meter away from expressway/kloc. Is it noisy?

Houses near expressway 1km are very noisy. And it's not far from the expressway, about 1km. For example, when a big truck passes by, you can hear the sound of that engine. Especially in the dead of night. Very noisy. But when it comes to transportation, it is more convenient.

In real life, the farther away expressway is from the noise source, the lower the noise is. Usually, noise will have a decay process in the air. However, sound waves will also be disturbed by surrounding greening and wind speed, blocked or absorbed by low-rise greening and buildings, and the noise will be reduced after repeated refraction and reflection, while high-rise buildings will be more noisy when they are completely exposed to the three-dimensional propagation of sound waves. In addition to traffic noise, residents living in high-rise buildings are often affected by wind noise, and wind may also become a noise source.
