Sound is a traveling wave which is an oscillation of pressure transmitted through a solid, liquid, or gas, composed of frequencies within the range of hearing and of a level sufficiently strong to be heard, or the sensation stimulated in organs of hearing by such vibrations. Sound waves are characterized by the generic properties of waves, which are frequency, wavelength, period, amplitude, intensity, speed, and direction (sometimes speed and direction are combined as a velocity vector, or wavelength and direction are combined as a wave vector). So each of the properties of sound, the frequency, wavelength, period, amplitude, intensity, speed, and direction all can control the loudness of the sound that can be perceived by humans. When we turn up the volume on a radio it changes the degree of sound intensity or audibility, thus changing the loudness.
