High level source

ACOUSTICS AND VIBRATIONS
High level acoustical source for test
benches
The acoustical sources are designed to provide a high level acoustical
excitation for tests in duct. They can be adapted with the media: flow,
temperature or static pressure. An enclosed version is available for
tests with low acoustic radiation.
