Figure 2, below, illustrates the noise output
from a very loud RPM™ class where the noise
level was 99 dB. At this level, it’s only safe
to be exposed for 20 minutes. A 50-minute
class like this is exposing the instructor to
2.5 times the daily workplace noise limit.
You’ll notice also that apart from the first few
minutes of warm up and the last couple of
minutes of cool down, the noise level pretty
much hovered between 94 and 102 dB
throughout the class. The instructor cranked
up the volume and left it there!
So what are some ways to use music in
your classes and lower your risk? A better

alternative might be to mix it up and use volume
as a way of creating interest and variation in the
class. Volume could also be used as a way of
introducing interval training during a class: you
could use low volume to indicate a low intensity
period and follow it up with a higher volume to
mark a high intensity period.
Better still, experiment with tempo. The
advice from physiologists is that music
tempo is the most important factor for
increasing exercise speed and heart rate.
Research conducted in cycle classes
shows that increasing the tempo of music
significantly increases cyclists’ pedal power,
speed, and heart rate, so look for tracks with
higher beats per minute rather than simply
turning up the volume.
You could also explore other creative
solutions to get your clients motivated.
Why not consider using visual rather than
auditory stimuli – or spice up your timetable
by holding some ‘quiet’ classes? Advertise
these to your participants and get their
feedback – you might be surprised by how
many people turn up.
