Noise exposure risk assessment and noise reduction at workplaces facilitated by the use of information technology achievements
there is also a link to a recorded sound signal. The machine
can be listened to by clicking on the link. It is possible to
include signals for the sound of the machine before and
after actions to reduce the noise have been performed.
The data sheet of this machine can be seen in Figures 2a
and 2b.
Information is given on the machine and the sound pressure
level measurement. Both the A- weighted equivalent level
and the A-weighted octave band levels are presented. In the
Comment field (“Kommentar”) information on this machine
compared to other similar machines is given. Possible noise
mitigation measures (“Möjliga åtgärder”) is also stated

data presentation, all departments and workshops can
be accessed. There is also a link to the ordinary report,
with the result of personal noise exposure measurements
compared to action and limit values. Some educational
material on principles for noise reduction is available at the
link “Principer för bullerbekämpning”.
Interactive training on noise and measures
against noise at the workplace
An important task for employers at companies with noise
exposure levels at or above the lower action values is
to provide training on risks of noise exposure. Prevent,
which is an organization owned by Swedish employers
and employee organizations, has published an interactive
training tool program distributed on a CD based on a
manuscript made by ÅF-Ingemansson. The tool is called
“Ljud och oljud”, which means “Sound and noise” and is
made in the Swedish language.
The tool is the first complete tool to create a good sound
environment in all types of workplaces. It was produced
with the purpose to aid employers and personnel all the
way from the identification of sound as annoying, interfering
or hearing damaging to the reduction of noise. It can be
used by those who want to learn more, to choose noise
mitigation measures, to hire a consultant, to buy new
machines or rebuild their premises. It has two levels, one
for non-specialists in companies and one for experts-to-be.
There are more than 150 examples of how noise problems
have been solved in different types of workplaces.
