The G.R.A.S. 43AG Ear and Cheek Simulator represents the section of a head important for realistic reproduction of the acoustic properties of the ear of an average human head. It allows the use of an ITU-T type 3.3 pinna with a Shore hardness of 55 – 00 or 35 – 00 to be used with an IEC 60318-4 (formerly IEC 60711) Ear Simulator.
Different KEMAR Ears are available for the Type 43AG: small – large and left – right in soft and very soft versions are available.
