This Solution allows to measure Sound Power based on the measurement
of sound pressure levels at microphone positions around a
source under test. Thus, the Sound Power Solution is complementary
of the Sound Intensity Solution
that is based on the measurement of the sound intensity as
recommended by ISO 9614. Using the OROS Solution, based on
a task dedicated interface that guides the user step by step,
Sound Power is measured in an easy and efficient way. Once
the initial set-up of the microphone test bench has been organized,
the measurement can be repeated day after day with no special
expertise required. The Sound Power Solution is then well
adapted for products noise test qualification and trials in
R&D. Furthermore, the Sound Power Solution follows the
recommendations of the international standards ISO 374x and
in particular of ISO 3744. It is then the perfect tool for
regulations noise tests as for example specified by the European
directive 2000/14/EC. Sound Power Test reports can be customized
and are automatically generated using Microsoft Excel. Based
on OROS Analyzers, Sound Power can be measured acquiring all
microphone positions at once allowing a one shot run of the
source. In the most demanding configurations, especially when
some specific directivity measurements should be carried out,
up to 32 microphone channels can be handled in real time with
a type 1 precision. These possibilities let the solution user
be flexible, secure and efficient for any type of test bench
configurations.
