Noise

Not only does noise pose a risk to hearing, it can make people ill and diminish employees? performance
These are exactly the points we can explore and illustrate in the noise practical facility. The IAG workshops have a number of model workstations, at which seminar participants can learn the methods used to measure noise immission. Quantitative assessment of employees' noise exposure naturally leads to the question of how noise can be reduced.

Participants can perform experiments independently on machinery noise projection, room acoustics and enclosure of noise sources, depending on the length of the seminar. The ideal outcome is for participants to go back to their workplaces and apply their newly acquired knowledge in a noise-control programme that can serve as an example to others.
