There are two main types of sound wave attenuation in air: sound beam diffusion and medium absorption. The attenuation coefficient of sound wave in air depends on the temperature and humidity of the air. Of course, sound is lost in air, and it travels so far because the initial intensity of the sound wave is very large.
