Description

Designed for wideband measurements on handset telephones where realistic acoustical loads are needed. Wideband Ear Simulator for Telephonometry Type 4195 is designed for wideband measurements on handset telephones where realistic acoustical loads are needed. Fulfils the standard ITU – T Recommendation P.57, Artificial Ear Type 3.2 low- and high-leak. Type 4195 has been developed for use in combination with Telephone Test Head Type 4602-B and Mouth Simulator Type 4227. USE SCENARIOS Development and conformance testing of all types of telephone handsets using Telephone Test Head Type 4602B Realistic measurement of telephone receive response The two grades of well-defined leakage make it possible to simulate the average real ear loss for telephone handsets which are held either comfortably tight (low-leak pinna) or loosely (high-leak pinna) against the human ear. The ear simulator is recommended for measurements on supra-aural and supra-concha earphones, both sealed and unsealed, practically covering all kinds of earphone design. The ear simulator can be used for wideband telephonometry in the frequency range 100 Hz to 8 kHz.
