Final answer:
The sound emitted by a dog whistle is beyond the absolute threshold of human hearing and is an example of a stimulation that is beyond our absolute threshold.
Step-by-step explanation:
The sound emitted by a dog whistle is beyond the absolute threshold of human hearing because it is too high to be detected by human ears. This is an example of a stimulation that is beyond our absolute threshold.
Humans can normally hear frequencies ranging from approximately 20 to 20,000 Hz. Sounds above 20,000 Hz are called ultrasound. Dogs can hear sounds as high as 30,000 Hz, which is why they can respond to the sound of a dog whistle, producing sound outside the range of human hearing.
Therefore, the correct answer is C) Ultrasonic Threshold.
