The two sounds differ primarily in: (d) timbre

Work Step by Step

Since the notes have equal loudness, the intensity level and the amplitude are equal. Since the fundamental frequency is the same, the pitch and the wavelength are equal. However, we will be able to hear a difference between the notes from the trombone and the bassoon because the relative amplitudes of the overtones they produce will differ. This is what gives each instrument its characteristic sound, and it is called timbre. The two sounds differ primarily in: (d) timbre
