no. use of the terminology "trumpet" in Revelation is an analogy whereby a trumpet is used to signify a "call to action" or a "notification/signification of an event activation/occurrence. they serve to assist those who watch and prepare for these events prior to their onset as well as to verify their having come to pass so that the watcher knows and understands what he is witnessing as the events unfold, who the players are, and where exactly he stands in the timeline of a multiple event scenario.

it has nothing to do with real trumpets and/or the sound they make other than in allegorical correlation to the fact that when a trumpet is sounded in battle it is done to signify the onset of an event and/or to deliver a "call to action" for the troops in battle accordingly.
