An early pilot study has indicated that
the binaurally measured sound level at the ears doesn’t differ much between
different practice rooms, however the subjective loudness does. It seems as the
subjective loudness is influenced mostly by the later arriving sound and the
character of the sound. This study goes in depth with this problem for
classical trumpet players since they are exposed to high levels. The main goal
is to indicate better ways for acoustic consultants and end users to find
parameters with high correlation to the perceived loudness that can be
predicted and measured. In Sweden the legislation for maximum sound exposure
levels for musicians at work is the same as for factory workers. The
legislation only takes into account the measured sound levels. However the risk
for hearing problems, like tinnitus and hyperacusis is also influenced by
stressors. The perceived loudness is therefore important from a sound health
point of view.
