0001-2 5. A plane flies toward a stationary siren at ¼ the speed of sound. Then the plane stands still on the ground and the siren is driven away from it at ¼ the speed of sound. In both cases, a person sitting in the plane will hear the same frequency of sound from the siren. A) True B) False 6. The just noticeable difference (JND) of hearing is larger for softer sounds. For example, a 1 kHz sound that starts at 80 dB has a JND of about 0.5 dB, while the same 1 kHZ sound that starts at 30 dB has a JND of about 1 dB. Which statement below best describes the interpretation of this experimental result? A)
