Why do motorcyclists talk loudly to motorcyclists?

Sound travels not only directly to the ear, but also through refraction, so people's voice becomes very quiet in an empty place.

When riding a motorcycle at a high speed, because people can only hear the sound of others directly, there is no refraction, so they can't hear clearly with the roar of motor. Therefore, cyclists should speak loudly to cyclists.
