"A professor at the college explained to his students that this theory of hearing is similar to piano strings. If you sound a note with a tuning fork near a piano, the piano string tuned to that note will vibrate." This statement is an example of the place theory.

Explanation:

Each of the sound is originated from a specific source or reference point, and that the different sounds thus posses a more different features then the rest, while we have to make our concepts clear about the sound waves that each bit of the sound wave posses a more different pitch and that is also due to the unique form of vibration inside the space under consideration. While, the origin of the sound wave must be taken into account and its position inside a given medium.
