Contract awarded for conducting emissions, fuel consumption and noise testing
on selected two pacific national locomotives to verify oem emissions reduction and fuel economy claims from tier o+ emissions upgrade kits.
the centre is also equipped with a noise testing
system considered the first of its kind in the UAE.
But David Konyn said he and the neighbor have reached a tentative agreement for noise testing
that would allow the construction to go forward this spring and summer.
The new test tracks will enable train performance testing under various conditions: for example, operation at a maximum speed of 100km/hour, continuous operation, and noise testing
In a change to previous years, there will be no noise testing
, scrutineering or documentation the day before - all will now take place on the morning of the event.
In this situation, the Sterling police did not do any noise testing
Because Boeing had, by then, adapted its own transonic windtunnel to enable acoustic testing for propeller-driven projects, it was decided that, if Rolls-Royce were to offer an engine, the UK had to develop a windtunnel capability for propeller performance and noise testing
at high speeds," he says.
Suitable for a wide range of applications, from noise at work assessments to vehicle noise testing
and environmental noise measurements, Cirrus' CR:260A sound level meters are easy to use, yet capable of meeting sophisticated modern noise measurement guidelines.
835 standard recommended a test methodology for stationary noise testing
, the new amendment enhances the standard by adding comprehensive test methodology for non-stationary noise.
In addition the low speed model of the 747-8 was used at the Low Speed Acoustic Facility (LSAF) at Qinetiq in Farnborough, England and noise testing
was also conducted at the LSAF at Qinetiq.
Ongoing noise testing
of the Trent 900 engine for the Airbus A380 superjumbo, followed by similar, specialist testing on the Trent 1000, being developed to power the Boeing 787 Dreamliner, is scheduled to begin at the Mississippi centre in the second half of 2007.
The UT-103's best noise testing
results occurred against ambient noise.
