Re: Question on air scrubbers / machine noise levels

[Guest guest]

I believe the noise to which you are referring may be caused by vibrations from rotating machines.... motors, drums, blowers, air handlers, etc, etc. Much of those vibrations may be removed [absorbed] by vibration dampers installed at the point where the device is mounted. Dampers are needed with refrigerators, washing machines, spin dryers and air handlers. However with air handlers the installation is more involved as mounting is often not onto a fixed surface. In the industrial environment vibration dampers are readily used for all machinery. In the home noise often comes from old air ducts that tend to rattle and be noisy when vibrated by the air handler. Ken ------------------------- Question on air scrubbers / machine noise levelsSo the questions are:1. Have any of you wondered if the db levels from the machine noise of the equipment exceed thresholds for say, and 8 hour work day? 2. Are we, as an industry, causing noise pollution while remediating environmental contaminants (ironic if true)?2. Are there any commercial noise reducing products or applications or techniques in use right now that can reduce the background noise?I'm wondering if anyone on this board can help me with this. We get involved in a remediation project, we determine everything from PPE plans to air change rates within containments, we determine RH requirements, etc. Often, we are remediating part of a structure that is still occupied, be it a residence or workplace.I have not actually measured the noise levels, but I do know that complaints from both workers and homwowners are common, and I have had a good number of remediation contractors call me and ask me to stress to the client the importance of not shutting the machines off no matter how annoying they are.This noise is constant, can be in place for days, and can really add up - a bedroom that has a water loss may have air movers and dehu's in it for 2-5 days, then if there is mold found, you can add an air scrubber in there, dehu still in place since the return vent is sealed off and no conditioned air is entering, and so a homeowner could deal with this for upwards of 10 days.

One additional thought... If you are contending with temporary portable equipment like commercial fans or dehumidifiers then a vibration pad or two placed under the portable machine should dampen [decrease] much of the noise caused by the vibrating motors. Also the device should have been well maintained so that it does not rattle in a loose container. Dehunidifiers can be noisy because their construction is flimsy and the sheet metal housing simply rattles with age. If such is the case and can't be solved otherwise I'd also investigate noise cancelling sound generators now being developed that are suppose to cancel annoying acoustic vibrations. See: http://en.wikipedia.org/wiki/Active_noise_control for a complete explanation.
