Does a tree falling over in a forest make a sound if there is no receptor (human or animal ear) to hear it? In your answer, describe why you think it does or does not. Describe how you would test your hypothesis. Use relevant terms.

Yes. A tree falling over in a forest makes a sound even there is no receptor (human or animal ear) to hear it.

In terms of physics, sound is a vibration that travels through a transmission medium like a gas, liquid, or solid as an acoustic wave. Sound is the reception of these waves and the brain's perception of them in terms of human physiology and psychology. Only acoustic waves with frequencies between roughly 20 Hz and 20 kHz, or the audio frequency range, can cause a human to have an auditory sensation.

If sound is defined as air vibrations, then the falling tree most definitely creates sound because it causes air vibrations. A recorder with a microphone could undoubtedly capture those vibrations as sound even if no one or any other animal was around to hear it.
