No, it doesn't. There are two different things to consider. Mechanical vibrations generated by the falling of tree, and detection of those vibrations by human ear. It's the latter which we call as sound. Imagine two people standing next to each other with different hearing range say 20Hz-20kHz and 20Hz-22kHz. If an otherwise undetectable event takes place ...

The point is this: the existence of an object is not something that is independent of a subject. Colors exist because our eyes are able to process some physical phenomena and interpret it as a color manifestation. Otherwise, outside there's only energy (and perhaps not even that).

This does not seem so important for trees in woods, but the philosophical question extends to alien life on other ...

Without a measuring device to record it, there is a sense in which the recognisable properties of quantum particles such as electrons do not exist, just as the falling tree makes no sound at all. ‘Reality is merely an illusion,’ Einstein once admitted, ‘albeit a very persistent one.’ https://blog.oup.com/2011/02/quantum/

According to a conventional definition of the term "sound" When we define sound as the sensation of hearing by an observer when vibrating air hits the eardrums and is perceived by the mind then the air vibrations of a tree falling in the forest would not make a sound if there is no one hear to hear it. It is not an actual sound until the vibrating air ...
