implemented.
Some questions that you probably have, and that RAP-ONE can answer:
What will the noise increase be if I add another machine?
What will the impact of that new machine be on noise doses perceived by the
workers?
What will the noise reduction be if I install a silencer on a vacuum cleaner or if I
add an acoustic treatment to the ceiling?
How can I be sure my noise reduction process is structured?
Estimate of Noise Doses Perceived by Workers
Is it time-consuming for you to evaluate the noise doses perceived by workers after
round shifts, the modifications brought to noise sources, or the noise treatments that
have been implemented in a room? RAP-ONE allows you to do those calculations in a
short amount of time. Use our 3-step process, and voila!
2) Define the various groups of workers (name and exposure time at each receiver)
3) Calculate the noise doses perceived by each worker ( image ).
Choice of Optimal Treatments
RAP-ONE not only predicts the efficiency of the acoustic treatments in terms of acoustic
attenuation, but also in terms of cost-efficiency (decrease in decibels per invested
dollar).
Using the previously entered data (potential treatment types, costs, noise reduction,
etc.), the program calculates every possible treatment combination and indicates the
most cost-efficient solution. With a click of the mouse, you can obtain the noise map of
that combination or of any other calculated combination (
image ).
The evaluation of the performance of various possible treatments is simple: Apply the
acoustic treatments being considered for the room using the Absorbing Panel or
Acoustic Barrier tools, and then click on the Calculate Noise Map button. The room’s
new noise map displays the noise levels obtained with the added treatments. A
similar process can be applied on the room’s noise sources (ex., adding a silencer).
1) Position the receivers with the Receivers tool
