This link is a precision version with a base. It supports direct insertion into the 3.5 microphone port of a PC computer.
 

The IEC711 artificial ear adopts the IEC-711 human ear simulator as the coupling cavity, which is used to couple the earphone with the human ear for acoustic measurement by means of earplugs;
      Meet the following criteria:

IEC 60318-4:2010 Ed.1.0 formerly IEC 60711 Electroacoustics-Simulator of human ear and head, Part 4: Measuring plugged ear simulator for plug-in earphones;

SJ/T 10659-1995 An ear simulator for measuring plug-in earphones;
ITU-T recommends P.57, type 2 artificial ear
      IEC711 artificial ear technical parameters

Executive standard ITU-T P.57 sec. 5.2 Type 2 proposal and IEC60318-4

Frequency range 100Hz-10kHz ±1dB simulating human ear impedance

Coupling cavity frequency range 20Hz-16kHz used by coupling cavity

IEC711 test tool, precision production according to international standard earphone test requirements, professional factory processing and manufacturing, can test in-ear, moving iron, customized earphones and other tests. With the optional standard test pinna, you can also perform headphone testing, flat headphone testing and more. Commonly used functions include sounding curve, waterfall graph, sudden attenuation and so on.

The following document is the original IEC standard
1 Scope

This part of IEC 60318 specifies an ear simulator for the measurement of supra-aural and

circumaural earphones #xff08;used for example in audiometry and telephonometry#xff09; applied to the

ear without acoustical leakage, in the frequency range from 20 Hz to 10 kHz. The same

device can be used as an acoustic coupler at additional frequencies up to 16 kHz.

NOTE 1 This device has alternative configurations for supra-aural earphones and different types of circumaural

earphones. In practice, the alternative configurations can be realised through the use of adapters where necessary.

NOTE 2 Repeatability for supra-aural and circumaural earphones may get significantly worse above 10 kHz.
