sound reduction training?
(OP)
All,
We manufacture diesel powered construction equipment and sound attenuation has been a growing concern. We could either hire someone to come in and make suggestions, or we could have someone learn about the concept. I would like to learn about the task so we can do the job in house. Can people here make some suggestions about text books or training materials I can use to learn more about dampening our equipment and controlling the sound?
Thank you
Jim

RE: sound reduction training?
Do you have the equipment to make detailed sound and vibration measurements? By detailed I mean with frequency content, typically from spectra/FFT measurements ?
Not too many years ago I saw a report from a big name consultant. It included a slew of recommendations for mechanical upgrades/corrections based on his analysis made with an octave band filtered instrument. I was almost embarrased for the guy. Some basic, detailed vibration analysis measurements on the equipment and building surfaces would have eliminated about 90% of the "recommendations." If the custome happened to make a bunch of the modifications from the 90% group I think the the results would have been most disappointing.

I am not aware of any courses on NVH in the USA, but there must be many. In the UK ISVR runs several that are appropriate. With the advent of decent free PC software eg abravibe the barriers to entry are much lower than they used to be - my first 4 channel signal analysis computer cost 3 years wages.

I will do more searching on the faq's and spend some time on the web site seeing what I can dig up.
