ACOUSTIC CAMERA – HEXTILE
The Norsonic Hextile is a module based approach to acoustic camera that gives the user both portability and great resolution for a wide range of measurement situations. The array dish is based on a hexagon shape, given it both its name, and the ability to combine several tiles into larger systems.
With a single Hextile, the user has a small, portable and lightweight acoustic camera that can be used for a wide range of measurement situations. The Hextile is a USB based acoustic camera, with a single USB cable for both power and data transfer – no extra battery cable needed. The array is made from robust and lightweight aluminium, has 128 MEMS microphones, and is less than 3 kg in weight while having a maximum diameter of 46 cm. The low frequency limit for the Hextile is 410 Hz.

ACOUSTIC CAMERA NOR848A
Norsonic has the world’s most compact and performing acoustic camera for its size: the Nor848A-0,4 equipped with 128 microphones on a 0.4 meter surface. The weight is only 2.5 kg. The array is equipped with two handles for easy handheld operation. The small size make it possible to operate close to the source and in areas with limited space. With excellent high frequency resolution it is the perfect choice for searching for squeak and rattle noises and other abnormal noises from for example industrial products.
