In the aerospace industry research and development is crucial as failure of components can have major implications. Understanding how components of an aircraft behave and react in situations must be studied. Some of the testing needs come in the form of acoustic testing. Being able to identify a sound source can help determine a part failure. There is also the passenger comfort to take into consideration. The Acoustic Camera can help with both.
Loud engines and wind noise create a very dynamic environment in the interior cabin of an aircraft during flight. Furthermore, the amount of stress and vibrations experienced in flight can create many unwanted buzz, squeaks, and rattles. Whether it be a commercial airliner or private luxury jet locating these sources can be difficult yet imperative. With the Acoustic Camera, one is able to map these sound sources within a 3D model of the aircraft cabin quickly and accurately.
Understanding the noise emitted from an aircraft can help with its development and ability to confirm with standards in place (i.e. AIR902) to regulate acoustic emissions of aircraft. With the emergence of military drones, comes the need to make sure they are as quiet as possible to avoid detection. Movement toward the use of electric engines on personal aircraft creates new challenges in understanding where noise is being propagated. Using the Acoustic Camera can help meet these requirements.
There are many components that make up an aircraft. When everything is assembled in working order that contribution of each item to the overall sound level most be taken in consideration to achieve an acceptable noise level. There are also components that although may be the loudest contributor but not the most undesirable. When using the Acoustic Camera one can pin-point the undesirable noise sources to begin the necessary steps to mitigate them.
