AWA6161A (IEC126）Type Acoustic Coupler

Standard-Compliant Design — Manufactured per SJ/Z9144-1987, equivalent to IEC60318-5 (IEC60126), ensuring internationally recognized measurement accuracy.

High-Precision Frequency Response — Delivers ≤±0.5 dB accuracy across 200–5000 Hz and ≤±1 dB across the full 125–8000 Hz range.

Human Ear Simulation — Accurately replicates the acoustic behavior of the human ear canal for realistic in-ear headphone testing.

Flexible Microphone Compatibility — Works with both φ12.7 mm (1/2") and φ23.77 mm (1") SPL condenser microphones, offering setup flexibility.

Complete System Integration — Pairs seamlessly with AWA14422 microphones and AWA14601B/AWA14604 preamplifiers for a ready-to-use measurement chain.

Also Known as IEC126 Ear — Widely recognized industry-standard equivalent, ensuring cross-compatibility with existing IEC126-based test protocols.

Product Description

The AWA6161A simulated ear is an acoustic coupler that mimics the acoustic characteristics of the human ear. It can be used with a φ12.7mm (1/2 inch) sound pressure level (SPL) capacitive testing microphone (AWA14422 type) and preamplifier (AWA14601B or AWA14604 type), or with a φ23.77mm (1 inch) SPL capacitive testing microphone. It is used with accompanying audio measurement and analysis instruments to measure the electroacoustic characteristics of in-ear headphones. The AWA6161A simulated ear is designed and manufactured according to SJ/Z9144-1987 "Measurement of Couplers for Hearing Aids with In-Ear Headphones and In-Ear Headphones," which is equivalent to IEC60318-5 (IEC60126) standard. Therefore, this simulated ear is also known as the IEC60126 simulated ear or IEC126 ear. The photo shown in Figure 1 shows the assembly of the AWA6161A simulator ear, AWA14601B preamplifier, AWA14422 test microphone, and 1-inch to 1/2-inch adapter.
