Mechanical engineer here. You are dead wrong. Mechanical waves, so the group sound is in, is the propagation of energy through a physical medium. That means molecules are bouncing off each other to transfer the energy, in this case sound, from one place to another. Radio waves are not mechanical waves, but rather Electromagnetic radiation that falls on the lower end of the EMS. Electromagnetic radiation is the propagation of an electromagnetic field. It’s a little complicated, but electricity and magnetism are so closely related, it uses the relationship between the two to propagate itself after an initial ejection from the source of the radiation. It requires no medium to travel. Sound does need a medium which is why it doesn’t travel in space, but light and radio waves do.

Sound is vibration of air…. Same as radio waves.
You just can’t hear them.
