• Conforming to ITU-T Rec. P.57 (2011) Type 3.2 specifications；

  EC 900 High-Leakage Artificial Ear Shell is a broadband ear simulator used for call testing, specifically designed to measure the real-world response of telephone handsets during calls.

  EC 900 High-Leakage Artificial Ear Shell can simulate the average ear loss when the telephone handset is positioned at a relatively far distance from the human ear. It needs to be used in conjunction with an artificial ear that complies with IEC 60318-4 specifications and a preamplifier. The high-leakage artificial ear is equipped with a soft sealing ring, which ensures a good seal between the artificial ear and the surface of the product under test while preventing the product from being scratched during testing.
