Hi Chaps
Really need some help if possible. I have an installation of two 10 kw wall mounted Daikin Units in a classroom. In the book they are rated at 45Db High at 1 metre. The design consultant has just phoned me today and stated the maximum limit for any equipment in a classroom is NR30 or 39DB at 3 metres. I spoke to Daikin this afternoon to ask what the sound levels are likely to be at 3 metres and their advice was to use a sound meter after the install..Very helpful!!
Is there a definate way or calculation to work out the information i require?
Any help on this a big thankyou as have to phone the consultant tomorrow morning.
Thanks
Gareth.
