These symmetrical pinnae comply with ITU-T Rec. P.58, IEC 60318-7 and ANSI S3.36-1985, including testing of headphones and hearing protectors as well as measurements on telephones, hands-free communication devices and hearing aids.
The symmetrical pinnae for Head and Torso Simulator (HATS) Types 4128-C and D are used to obtain an identical positioning of the right and left part of the headset.
The symmetrical pinnae come in a soft (OO-35°) and hard (OO-55°) version, both complying with 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:![]()
