Durham Instruments, a distributor of Brüel & Kjӕr’s advanced measurement technology, offers a comprehensive range of high-performance acoustic arrays designed for precision noise mapping. These systems, which vary from compact two-microphone setups to large arrays with hundreds of sensors, enable rapid and detailed analysis of diverse noise sources across multiple industries.
Brüel & Kjӕr’s Customized Products Department works closely with clients to configure complete measurement systems tailored to specific needs. These integrated solutions combine specialized arrays with analysis software, positioning systems, and robotic controls. A prime example includes robotic-assisted microphone arrays for detecting acoustic leaks in hearing aids, while another application involves quality control monitoring during electrical transformer manufacturing.
When selecting an acoustic array, engineers must consider several critical factors including the operating environment, frequency range, required resolution, distance to the sound source, and whether the source is stationary or moving. Brüel & Kjӕr offers multiple array configurations to meet these diverse requirements.
Spherical arrays provide omnidirectional noise mapping for in-cabin or indoor applications using SHARP beamforming technology. Planar wheel arrays, available in various sizes and microphone configurations, serve both indoor and outdoor applications when paired with PULSE beamforming software. For outdoor use, foldable arrays offer portability and can be arranged in flat or angled configurations to reduce background noise interference. Compact handheld arrays perform near-field measurements in confined spaces, while grid arrays consisting of fixed microphone or hydrophone lattices specialize in stationary sound field analysis.
These advanced acoustic measurement solutions continue to set industry standards, providing engineers and researchers with versatile, high-resolution tools for noise analysis across multiple applications. The technology’s precision, adaptability, and customization options make Brüel & Kjӕr’s systems valuable assets in fields ranging from manufacturing quality control to product development and research.
