ITEM MODEL: HMS II.3 Head Acoustic Measurement System with Ear Simulator and Mouth Simulator
CONDITION: This system was previously used by a major electronics manufacturer. This item is in working condition.
DESCRIPTION: HMS II.3 is an Artificial Head Measurement System for measurements of the performance of close to-the-ear transducers: handsets, headsets, headphones, hearing protectors and hearing aids. HMS II.3 has been developed for acoustic measurement of telephone terminal equipment and meets the requirements laid down by ITU-T Recommendations P.57 and P.58. The simulation of the head geometry has been reduced to the acoustically relevant structures of the human anatomy and results in a recording technology which corresponds to realistic conditions for handsets and hands-free equipment.
