Good morning all,
We have recently installed an automatic carpet shredding system on site, made up of several shredders, ductwork, large manifold, cyclone/vacuum and skip. The noise is horrendous, especially from the cyclone, the manifold and the ductwork on any bends.
Installation of this system has lead to hearing protection becoming mandatory in the areas it is used. I am trying to seek a reputable sound specialist who can come assess our situation and provide us with a practicable solution to reduce the high frequency noise levels.
If anybody has a contact or knows someone who can help I would be very grateful, as the people I've had on site so far have not been very helpful nor got back with any solutions or quotes. Thank you in advance for your comments.

Try these people. I have been to seminars/talks given by them and they seem to have practical solutions to often complex problems. I have not used them directly to assess our systems and do not work for them. Hopefully this is not deemed to be advertising, I'm just responding to the query.

What do the firm who installed the Carpet Shredder advise?
I have used Castle Group from Scarboprough in the past.

Personally I would go back to the original purchase order - excessive noise means the system has not been designed & constructed in accordance with applicable regulations https://ec.europa.eu/growth/sectors/mechanical-engineering/machinery_en
From the directive: 1.5.8. Noise
Machinery must be designed and constructed in such a way that risks resulting from the emission of airborne
noise are reduced to the lowest level, taking account of technical progress and the availability of means of
reducing noise, in particular at source.

I have worked with this consultancy in the past and they may be able to offer you some advice on the issues as indicated in the other posts as well as assist with an engineering solution if this is the route you take.

They will use the same excuse as I hear all the time from machine OEM’s these days, which is that they can make it cheaper, but, the customer won’t pay.
Theybcan make all their machines quiet, but they won't sell any because the customers will buy the noisy nes from the competition, because they are cheaper.
It's the same with LEV, do you end users get your LEV CE marked?
If not why not, it's a legal requirement for it to be CE marked and compliant with the SMSR (MD), & supplied ith a DoC.
Annexe iv applies.
The LEV industry doesn’t do it, because it costs money, and the end users won't pay for legal compliance.
