ORIGINAL: pahunkboy if a tree falls in a forest; and no one hears it- did it make a sound??? A soundwave is nothing more than air molecules bumping into one another and causing a wave similar to the way you create ripples in water by dropping a rock into it. That's called compression and rarefaction. In order to 'hear' the sound that wave will produce you have to have a transducer, such as an ear. Without a transducer, you can't convert the mechanical energy of the air molecules into sound. So, to answer the question, if a tree falls in the woods and no one is there to hear it, does it make a sound .. the answer is no, it does not. Nothing to do with philosophy though. This is straight up physics. Celeste edited for typo Thats pretty neat. However, what you claim to be straight up physics misses one philosophical point out: How can you be sure that this is the only way to hear a sound? Composers imagine music - no airwaves, no transducers. Are they hearing the sound? It can be as vivid as the real thing. You divide the process into two parts: hearing, which the ear does through receiving the soundwaves, and soundwaves which the tree makes. The original problem states, "does it [the tree] make a sound"? Presumably you are not suggesting the tree does not produce those physical air ripples when it falls? Sound(waves) and hearing are two components, but they are seperate. Sound as a received sense is not something the tree would make anyway, as you elegantly point out, that happens in us - so the only thing the tree can make is soundwaves. The ear does not convert the airwaves into sound, it converts the soundwaves into the sensation of hearing. We hear sound. One part is us (hearing), the other part is external stimulus (sound/soundwaves).We dont sound sound. Sound is a name for a particular electromagnetic spectrum of energy, is it not? It is therefore external and seperate to us. Thus I suggest that the tree is able to produce the sound regardless of observation.
