EAR SIMULATOR, ARTIFICIAL HEAD AND MEASURING SYSTEM AND MEASUREMENT METHOD WITH USING EAR SIMULATOR AND ARTIFICIAL HEAD Russian patent published in 2018 - IPC H04R29/00 

FIELD: measuring equipment.

SUBSTANCE: there is a measuring system for acoustic device estimation, wherein the acoustic device provides an opportunity for the user to hear the sound by virtue of the vibrating element vibration. The system comprises the ear simulator, which is comprised of the artificial ear, which is simulated in accordance with the human ear, and the artificial external ear canal, which is integral to the artificial ear, and the microphone. The vibration is transferred from the artificial ear to the artificial external ear canal due to the fact that the acoustic device is in contact with the artificial ear. Moreover, the Shore hardness of the artificial external ear canal ranges from 20 to 60. Upon that, the microphone rests on the artificial external ear canal end. The artificial external ear canal is attached to the tubular area. The ear simulator is attached to the head simulator. The ear simulator comprises the section, which is made of the material that satisfies IEC 60318-7. The ear simulator additionally comprises the embedded in the artificial ear artificial cartilage, and the artificial cartilage is in the position, which corresponds to the antilobium in the artificial ear.

EFFECT: measurements efficiency upgrading.
