Bruel & Kjaer Sound & Vibration Measurement A/S

BK CONNECT ACOUSTIC CAMERA

This complete kit uses a hand-held microphone array to identify sound sources by creating noise maps in real-time – over a wide frequency range. The portable array is normally fitted with a tablet computer that shows you the real-time sound map of the area at which you are pointing. It needs minimal training to use, and the user can then quickly locate noise sources, take screenshots, and record video of interesting events and problem areas for further analysis afterwards. Instant playback lets you check that you are recording data correctly while adjusting any necessary settings, such as frequency range.USE SCENARIOS

• Detection and documentation of buzz, squeak and rattle (BSR) in vehicle cabins

• Noise source identification (NSI) and troubleshooting in aircraft cabins, cockpits, avionics and cargo bays

• High‐frequency acoustic leak detection

Because it operates in real-time, the acoustic camera is ideal for mapping moving objects and transient events. You can walk and stream video using a hand-held array, or mount an array on a tripod for stationary measurements. The acoustic camera can measure over a wide frequency range due to the fact that it uses both acoustic beamforming and statistically optimized near-field holography (SONAH) technologies.CHARACTERISTICS This complete system includes a 30-channel, irregular microphone array with a removable backing plate that allows measurements in in either the near or far acoustic field, using both acoustic beamforming and holography. It is relatively small, making it ideal for confined spaces. An integrated video camera feeds live pictures to the real-time display and recording functions. The kit includes a battery-powered LAN-XI data acquisition front-end giving up to 4 hours of battery life, and comes in a weatherproof carrying case.
