The DZ-9769 and DZ-977 pinnae with tapered ear canal for Head and Torso Simulator (HATS) Types 4128C and D are used to obtain an identical positioning of the right and left part of the headset due to the symmetrical design.

The tapered ear canal pinnae come in a soft (shore OO-35°) silicone material to mimic the human ear very closely in appearance and furthermore supports insertion and sealing of insert earphones as well as earphones placed hanging in the concha. The anatomical pinnae shape is the same as found in both the IEC and ITU-T recommendations.

To ensure high quality measurement results, the left pinna is a digital mirroring of the original right pinna, providing a set of symmetrical pinnae to be used with HATS.
