But today, as often, we have the boom boom boom of an Event happening in
a
large park about four miles away. Why does the bass part of 'music' have
to
be put out so loud?


It isn't louder. Bass has a lower wavelength than treble meaning it can
travel further without losing as much energy.

I am afraid that the absorption coefficient for sound under normal
atmospheric conditions is not very wavelength-dependent and does not explain
why brass instruments sound so loud. They sound loud because they really
can produce a hefty sound intensity.
