BK Connect Acoustic Camera

BK Connect Acoustic Camera works with BK Connect software enabling easy, real-time noise source location and mapping. View transient sound sources on-site, or record and save video for subsequent analysis on stationary and moving objects.

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.

Operation requires minimal training and the user can 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

  • Basic array measurements
  • Product noise source location and troubleshooting
  • Detection and documentation of buzz, squeak and rattle (BSR) in vehicle cabins
  • High‐frequency acoustic leak detection
  • R&D, quality assurance and troubleshooting for a wide range of industries, such as:
    • Plastics and rubber
    • HVAC
    • Medical devices
    • White goods

Operating 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 because 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.

CAPABILITIES
