The characteristic of a sound wave that is related to loudness is 'intensity'.
Объяснение
## Step 1The loudness of a sound is determined by the amplitude or intensity of the sound wave. The amplitude of a wave is the maximum extent of a vibration or oscillation, measured from the position of equilibrium. In the context of sound waves, the amplitude is related to the loudness of the sound.## Step 2The frequency of a sound wave is related to the pitch of the sound, not its loudness. The frequency of a wave is the number of waves that pass a point in a given period of time.## Step 3The wavenumber is the spatial frequency of a wave, which is the number of wavelengths per unit distance. It is not directly related to the loudness of the sound.## Step 4The wavelength is the distance between successive crests of a wave. It is related to the pitch of the sound, not its loudness.
