A nurse is conducting an audiometry test to differentiate between loudness and intensity of sound for a patient with suspected hearing loss. Which statement correctly distinguishes loudness from intensity?

Loudness is measured in hertz (Hz), and intensity is measured in decibels (dB).

Intensity refers to the frequency of the sound waves, while loudness refers to the duration of the sound heard.

Loudness is the subjective perception of sound by the patient, while intensity is the objective measurement of sound energy in decibels.

Loudness and intensity are both objective measurements and can be directly measured using audiometry equipment.
