Question

Answer 1

Answer:

Kat should get a whistle that emits sounds in the range of 23 and 54,000 Hz.

Explanation:

The hearing range is the frequency range that can be heard by the animals, including humans.    

Generally, the hearing range of humans is about 20 to 20,000 Hz and the hearing range of dogs is around 67 to 45,000 Hz

Dog whistles are the whistles which emits ultrasonic sound and are used for training dogs. Generally, the dog whistles are within the range of 23 to 54,000 Hz and thus, can not be heard by the humans.
