Observing sound at Brüel & Kjær
Annoyance from noise has become a key factor in the quality of life, with the result
that more stringent regulations and directives are being introduced to
minimise the impact of noise on the environment. To address the increased
need for noise measurement, Brüel & Kjær has launched a
state-of-the-art sound level meter and sound analyzer. A hand-held instrument,
the 2260 Observer™ can be used to carry out all the measurements and analyses
typically required for assessing environmental noise and noise in the
work place. For monitoring in places which are particularly difficult
to access, the analyzer can be left and the modem dial-up facility used
to remotely access the results. The user can define how often the analyzer
is to be “woken up” to make and store the required measurement
data. A number of software packages are available to enable the results
to be examined and analysed, including, for example, the facility for
the operator to record and replay sound events to aid post-processing
and the ability to edit noise levels on screen to give “what if”
situations.
