Question
Consider the audibility curves in the graph above. Suppose all animals listed in the graph are present, and a sound with a frequency of 5000 Hz is played. Which of the following statements would be correct?
Group of answer choices
The brachiosaurus perceived the greatest loudness of the 5,000 Hz sound
A sound of 1,000 Hz would need greater amplitude than the 5,000 Hz sound for the great tit to perceive the same loudness
A sound of 10,000 Hz would need greater amplitude than the 5,000 Hz sound for the dog to perceive the same loudness
A sound of 9,000 Hz would be perceived as louder for the human than the dog.
