Array-Paddle2x24

This portable handheld paddle features 48 double-layered microphone channels that allow for real-time Acoustic Holography measurements. The double-layer structure enables the measurement of acoustic pressure signals while particle velocity/ acoustic intensity on the measurement plane is calculated and mapped simultaneously. Furthermore, this microphone layout facilitates a differentiation between noise sources on the measurement plane or in the field behind the paddle. The double-layered microphones act like intensity probes, delivering a vector used to calculate an acoustic map. The paddle is available as an add-on to an Acoustic Camera system or as a stand-alone solution. The kernel for Acoustic Holography calculations is embedded in NoiseImage.
