IAC of Winchester, global leader in noise control, was called in by Finning (UK) Limited to supply noise control solutions for emergency stand by generators within Addenbrookes hospital in Cambridge The two Caterpillar diesel standby generators were to be installed in a plant room directly beneath the Intensive Care recovery ward, with noise attenuation being a critical aspect of the project

The Institute of Animal Health's new research centre at Pirbright in Surrey is to benefit from IAC noise control solutions.
Silencers for multi-million pound mansions
IAC commissioned by owners of multi-million pound homes to design and install noise control solutions.
The objective of the project was to maintain the best possible environment for patients should a national grid power failure occur.
Simon Lewis is Facilities Manager at Addenbrookes for whom having standby generators in place is a crucial risk management strategy.
"The acoustic spec on this project was very stringent at NR40 in the ward above, that's little higher than the level of ambient noise or bird song".
"We have regular test runs of these standby generators and overall I'd say the sound attenuation has been very successful." IAC installed two acoustic enclosures constructed using our high performance acoustic Noiselock panels, with compatible inlet and discharge air attenuators.
The secondary acoustic ceiling would also minimise noise transmission from the generators to the ward above as well as provide much needed sound absorption in the generator room.
IAC Boet Stopson engine exhaust silencers were also supplied as part of the turnkey package.
Gordon David is IAC's Business Manager, Power: "The acoustic spec on this job was particularly demanding, and it wasn't helped by the prefabricated nature of the building's structure".
"Being able to supply all elements of a job like this is our strength".
"We were very pleased with the spec achieved".
The resultant noise levels attained are: NR40 in the recovery ward above; 66dBA inside the generator plant room itself; and 66dBA at 1m from inlet and outlet attenuators.
Chris Connors, Sales Manager, Power Projects, Finning (UK) Limited said: "The challenge of Addenbrookes was significant".
"A low plant room ceiling, a tight noise limit - and a patient ward immediately above".
"Working with Finning, our acoustics and ventilation subcontractor, IAC, helped us to deliver the optimum solution for the project and satisfy the client's brief.".
