muse generator sound proofing
muse generator sound proofing
(OP)
All,
Any suggestions on how to sound proof or minimize the noise coming from 3 muse generators(1500kw each).We are thinking of installing a 20 feet wall around the perimeter but I know if this approach is the best.Maybe one of you already encountered this kind of problem. These DG's are in close proximity to traffic and housing area.
Thanks in advance.

Putting a wall (block or brick) around can actually make the situation worse by reflecting the noise.
It could also affect airflow and cause overheating of the sets.
Can we have some more details - like how much niose you want to reduce (in dB(A) at what distance?

If so, any sound attenuation will have to be done external to the package, as trying to add sound damping to those units takes an already marginal air flow unit and causes ambient capability problems. I have seen many people try and "fix" surplus units with poor operational results.
How long in this particular site? If longer term, more than a year, a sound wall is likely your best option. We put four of these units in service a few years ago in Hawaii using hay bales as a sound barrier, only marginally effective, but enough to keep the neighbors complaints down until the new units could be installed.
If you need the generators long term and can't get new units then the best solution if you need sound attenuated units is to repackage the MUSE units, and you'll likely need to include the radiator in the list of things not reusable.

I note that block walled buildings have been suggested. This approach was used when a customer wanted less noise pollution than was afforded by the concrete block enclosure.
We also had good results adding a labyrinth to the air discharge path. We would add a small room (about 2 ft. or 3 ft. by the width of the building) in front of the air discharge so that the air flow was diverted up and then back over the roof of the generator shed. The exhaust would also be piped up this space. Fiberglass on this wall where the air discharge strikes it is effective.

These were not considered "tactical" units, but for utility type service in rear areas or for civil response, and assumed they would typically operate at something well below rated output. The basic units were usually pretty good iron, but the controls and packaging usually leaves a lot to be desired, if you're doing something longer term with them I would definately take a hard look at repackageing them with cooling systems sized for installed ambient conditions. Also the typical MUSE units had pretty lousy on board control systems, so you may want to take a close look at those as well and put something together you can service and maintain.
Hope that helps.
