Hi Everyone I am finishing up a small workshop with a concrete floor, plaster skimmed block walls and a 3m/10ft painted OSB ceiling. Right now the space is empty so it feels more live\louder than it will once full of machines cabinets etc but still clearly it needs something done about the acoustics.
I have been looking into sound absorbing panels of various types (melamine foams) and it appears that while they would be easy to install and not too expensive they are most effective with frequencies over 2 kHz while my research indicates that the bulk of the spectrum produced by manual machines (a couple lathes, a manual mill with max 6.5k rpm) and those sorts of things is below 2 kHz. Having a physics background I am well aware of the wavelengths of lower frequency sounds (on the order of meters) and the fact that foam is going to do nothing to attenuate them. Does the higher frequency attenuation still make a significant difference in terms of comfort etc? It does seem that high frequency noise is more annoying than lower anyway.
Does anyone have experience as to the most effective way to acoustically treat a workshop space? Or should I just wear earplugs all the time which I should probably be doing anyway
thanks
Luke
