Question

the loudness of a sound is determined by the: frequency of the sound wave medium through which it travels amplitude of the sound wave wavelength of the sound wave

Explanation:

The loudness of a sound is directly related to the amplitude of the sound wave. A larger amplitude means more energy is carried by the wave, resulting in a louder sound. Frequency determines pitch, the medium affects speed and attenuation, and wavelength is related to frequency and speed (not loudness).

Answer:

Amplitude of the sound wave
