- The IEC 711 coupler is a standard for insert-type earphones that became an IEC standard in 1981 and is standardized up to 10 kHz1. The coupler is used to measure the acoustic performance of earphones and simulates the insertion of an earplug catheter into the ear canal or auricle2. The IEC 60318-4 standard used to be called IEC 711, so ear simulators based on this standard are often nicknamed "711 simulators" or "711 couplers"3. It's important to note that the 711 ear simulators only simulate human hearing from 100 Hz to 10 kHz3.
