From the "meep meep" of the smallest scooter to the "BLLLAAAAAGGGGGHHH" of the largest seagoing container vessel, vehicles seem to have horn sounds that, in an auditory way, seem to indicate their mass. Of course, nothing prevents a designer from putting a "large" sounding semi truck horn into a mini automobile, it seems one would only do this for a joke and indeed, I can imagine it would make people laugh because of the unexpected mismatch between the vehicle and its warning sound.
Are there actual engineering guidelines that drive such design decisions? Presumably, from a psychological acceptability standpoint or from safety or general human-machine interface principles?
Note to audience: I tried my best to find the most appropriate SE mini-site. We have "Sound Design" which seems to relate to music; and "User Experience" which doesn't say so but seems 100% related to software design.
Note to site moderators: A tag for usability engineering or human machine interface design would be helpful.
