The actual SPL value on site will be between the stated SPL and SWL depending on
the acoustic environment in the machine room.
•
In a typical machine room without any noise absorbing materials, the actual SPL will be
approximately 14 dBA higher than the stated SPL (free field value).
•
Checking the actual SPL must therefore always be accompanied by measurements of
the acoustic environment of the machine room. Alternatively, ISO 9614-2 could be fol-
lowed at the installation site to obtain SWL comparable values.
•
Be aware of local/national requirements for the use of ear protection. Generally, it is
recommended to use ear protection in machine rooms.
