ADDENBROOKES’
PATIENTS BENEFIT FROM EMERGENCY SOUND OPERATION
 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 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 Boët 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."
