Ear and Mouth Simulators
Ear and mouth simulators are vital for product development, quality assurance and production line quality control for any products – such as earphones and smartphones – that require realistic acoustic human-like testing.
-
TYPE 4227 + 4227-A
Mouth Simulator Types 4227 and 4227-A are high-performance artificial mouths conforming to ITU-T Rec. P.51 and delivers highly accurate and repeatable electroacoustic measurements.
-
TYPE 4195
Ear Simulator for Telephonometry (ITU-T Type 3.2 coupler)
Wideband ear simulator designed for measurements on handset telephones where realistic acoustical loads are needed.
-
TYPE 4946
2 cc Click-on Coupler is designed for measurements in accordance with ANSI S3.7 (2008) and IEC 60318-5 (2006) standards, and is optimized for repetitive testing hearing-aids in the laboratory and on the production line.
-
TYPE 4930
Artificial Mastoid designed for the calibration of bone-conduction hearing aids by simulating the mechanical impedance of the human mastoid.
-
TYPE 4152
Artificial Ear with 6cc coupler
Designed for electroacoustical measurements on insert earphones and headphones to be carried out under well defined acoustical conditions.
-
4157型
人工耳/イヤーシミュレータ（マイクロホンとプリアンプ付きIEC 60318-4カプラ）
チューブやイヤーモールド、イヤーチップなどを耳に挿入するインナーイヤーイヤホンの測定用に設計されています
-
TYPE 4153
Artificial Ear with coupler designed to enable electroacoustical measurements on insert earphones and headphones. The Artificial Ear fulfils the requirements of IEC 60318–1 and has an acoustical impedance similar to that of a human ear. <br>
-
Type 4987
A range of ear simulators designed for realistic and comparable quality control testing of earphones, ear buds, smartphones and headsets on high-volume production lines.
-
TYPE 4185
Ear Simulator for Telephonometry (ITU-T Type 1 coupler)
Designed for measurements on handset telephones requiring an IEC 60318-1 coupler, including handsets with high impedance earpiece where sealed conditions are required.
