Key Features

Perfect, true directivity sound reproduction

By replicating human head and ears, the artificial head reproduces a spatial sound field with incredible fidelity.
Highly increased accuracy for differentiating between single sound sources and their localization

Head and torso construction

"Plug in" ears are made of tear resistant silicone rubber; together with head and torso, moulded to anatomically precise contours, they yield a faithful acoustic directivity pattern
Microphones accessible for replacement by means of rear panel removable with a single thumb screw

Acquisition front-end

Output of the manikin connected to any acquisition front-end,
Preferably to NetdB-DAQ12, our sound quality oriented platform: 12 channels, real-time equalization, audio digital outputs, 2 analog outputs, data storage on the disk, up to 4 synchronized manikins + RPMs
