The Norsonic Nor848B Acoustic Camera uses acoustic beamforming arrays, commonly known as acoustic cameras, enable the user to visualize different sound sources at different frequencies and source strengths. The resolution and ability to resolve sound sources spaced closely apart, and at lower frequencies, are mainly decided by the overall size and number of microphones of the equipment being used. 

Although image manipulation and deconvolution techniques on the beamformed results might give added resolution, in practice the properties of the array still influence the results. This size versus resolution criteria is the crux of the acoustic camera market. The Nor848B answers the need for a small, lightweight, and portable acoustic camera while offering excellent resolution and the option to configure for low-frequency measurement with additional Hextiles.ight ad portable acoustic camera that offers excellent resolution with the option to configure for low frequency measurement.
