Dust collectors noise pollution


#1

Beginner: if i have dust collectors the sound of each of them is
measured at 55 Decibels. How many decibels for 2 machines working at
the same time? for 3, for 4, for 5 6.7.8.9.10. what is the maximum
level of decibels acceptable in a workshop? 8 hours a day. many thks
by advance for every replies

the limit is without hearing protection. see if you can locate an
environmental health person, i took the class at eastern kentucky
university over 30 years ago so i doing it from memory. i did
research paper on the sound level in a moving ambulance.

Noise is an interesting subject. The less of it, the better, but
here are some numbers. 120 db (decibel) is a pain threshold. At 120
db an actual physical pain is experienced. Anything bellow 40 db can
be considered quiet. It is important to know that decibel scale is
logarithmic. For every 6 db, the power of sound doubles, so 55 db is
8 times as powerful as 37 db.

Multiple sources of sound can be cumulative, but not necessarily so.
Two sound sources 180 degrees out of phase will cancel each other.
All depends on installation, room resonances, and etc… Mounting on
sound absorption materials like high density rubber, can
significantly reduce the noise. It is a difficult to give practical
advice because so much depends on room geometry and workbench
construction. If you know someone with loudspeaker design
experience, they can be very valuable to help to to mitigate the
noise.

On the same subject, I am planning to buy a compact dust collector
for my workbench. I have an aversion to machine noise, and I’m
looking for the quietest model available. I’m considering the Quatro
Basic Dust Collector (available at Otto Frei
http://www.ganoksin.com/gnkurl/quatro ) which is advertised as being
"whisper quiet". Does anyone have experience with this dust
collector? Does it function well, and is it really as quiet as a
whisper?

Thank you.
