Answer: modes of travel

Sound is a mechanical longitudinal wave, whose main characteristic is that it necessarily needs a medium to propagate; unlike electromagnetic waves (radio waves) that are transverse waves and can propagate in vacuum.

Therefore, the main difference between both waves is their different modes of travel, while sound needs a medium to travel, radio waves not.
