Although most commonly associated with a moving object emitting a tone (like a car or train), a sound may also be doppler shifted if the listener is moving or (even less obvious) if the air medium is moving between a stationary tone and stationary listener.
My question is: If the only way allowed to observe a tone generating object is by listening once, can a distinction be made whether the object, the listener, or the air is moving?
Additional constraints are:
- The tone generator frequency at its source is fixed and known
- Only one listener observation may be made yielding a single frequency from which (taken with constraint #1) the amount of doppler shift can be determined.
I'm not sure I'm allowed to say this (since this is my first question ever to post here), but I think the answer is no, but wanted to make sure I considered everything. (Apologies for my wordiness & thanks for your time)
