Introduction
1.1 What is the Acoustic Camera?
BK Connect™ Acoustic Camera is a complete system for real-time noise source identification
(NSI).
It is a versatile tool designed for use in the aerospace and automotive industries, but has
applications in many other industrial environments. BK Connect Acoustic Camera is equally
suited to NSI troubleshooting in aircraft; buzz, squeak, and rattle (BSR) detection in vehicle
cabins; and high-frequency leak detection.
How to Use the System
Use BK Connect Acoustic Camera to locate and view transient sound sources on site using the
lightweight, hand-held array. All you need to do is aim, shoot and measure. Using a connected
PC or tablet, the system allows you to:
• Take, save and share screenshots
• Make, save and review recordings
These streaming and playback capabilities are included in the BK Connect Array Analysis software,
which is the heart of the system. The time recordings can be analysed further, for example, to obtain
sound quality metrics using BK Connect post-processing software, which is available separately.
Measuring with the System
BK Connect Acoustic Camera can be used either as a simple detection tool or a measurement
device. When used as a measurement device, the system is capable of stationary and non-
stationary measurements in both the near and far acoustic fields:
•Near-field measurements: Use the array
without the reflective plate and apply SONAH
(statistically optimized near-field acoustical holography).
With the SONAH method, the software will show either pressure or intensity
•Far-field measurements: Use the array
with the reflective plate and apply beamforming.
With the beamforming method, the software will show either pressure contribution or
intensity
