Array Analysis - 8430

This application acquires acoustic data for noise source location applications and creates sound maps using sound intensity and sound pressure overlain with synchronous video. 

BK Connect Array Analysis is the start point for all array and multipoint tasks and supports all aspects of the measurement process, including measurement control, result validation, data handling, and repetition of measurements. Ready-made templates help the operator set up the system for routine measurements within seconds.

 

The solution uses a hand-held microphone array to create a portable acoustic camera system: A complete kit for real-time noise source identification that needs minimal training to use. This enables you to quickly locate sound sources, take screenshots, and record videos of interesting events and problem areas for further analysis. Instant playback confirms that you are recording data correctly while adjusting settings as necessary, such as the frequency range.

Data can be acquired from any multipoint set-up; from the hand-held array to large multi-array setups can simultaneously measure with well over 300 channels. After data acquisition, the data can be transferred to array acoustic post-processing applications, such as PULSE Acoustic Beamforming Software Type 8606, for more advanced analysis.

CAPABILITIES

  • Measure and record audio and video for an event
  • Spectrogram yields full overview during measurement and playback
  • Display options include graphs of sound pressure, sound intensity, and sound power
  • Measures over wide frequency range using beamforming and SONAH
  • Up‐and‐running in under 20 seconds
  • Remote control mode via a tablet device 

A few tasks associated with this application may require initialization in PULSE LabShop. The legacy license for LabShop is embedded with this BK Connect license.
