Abstract: An apparatus, comprising: a manikin with at least a head portion and an ear portion; wherein the head portion has an inner side and an outer side and accommodates a mouth simulator including an electro-acoustic transducer. Further, the apparatus comprises an electrodynamic vibrator with a vibrating rod wherein the vibrating rod is coupled to the manikin to exert a vibrating force at the head portion; and wherein the vibrating force induces vibration of the manikin at least at the ear portion. Thereby more realistic electroacoustic tests on devices under test such as such as headsets, headphones, earphones, hearing instruments and active hearing protectors can be performed.
