Artificial Ear — Type AE2000
1. Introduction
The Artificial Ear Type
AE2000 is a complete test jig for acoustical measurement on earphones coupled
to the ear by inserts such as tubes and ear moulds.
Artificial Ears Type
AE2000 consist of an acoustic coupler, RST condenser microphone and
preamplifier and a base plate, which all parts are made of stainless steel and
no any magnetic material.
2. Features
•Conformed to IEC and
ANSI standards
•Complete
reproducibility and steadily of results
•Well-defined measuring
conditions
3. Components
The Artificial Ear Type
AE2000 comprises the following main components:
•Type
SC0002 IEC 60711 Ear Simulator
•Type RSTP
4000-S 1/2 inch Pressure Microphone Preamplifier, Wide
Frequency
•Type
SC0006 Base Plate
4. Artificial Ear Type AE2000
Artificial Ear Type AE2000
fulfils the requirements of IEC 60711 and is defined for simulating the
acoustical load of the human ear under no leakage conditions. The coupler fits
1/2 inch Microphone and 1/2 inch Microphone Preamplifier mounted in the housing.
The coupler also mounts directly on the preamplifiers by the Adaptor Ring
supplied.
5. Additional
Equipment
The following
additional equipment is required for making the necessary measurements:
• Power supply
for the 1/2 inch Preamplifier(e.g. the RStech type PM2000-S, Fig.4)
• Calibration
source for the microphone (e.g. B&K 4231)
• Audio analysis
system, which can generate testing signal and analyze the recording signal from
the DUT (TrustSystem, Fig. 3)
