AB  - An ear simulator produces an acoustic transfer impedance similar to a real ear. It has a cylindrical volume corresponding to an average adult ear canal and acoustic impedance similar to an average normal eardrum adjacent to a microphone at one end. Devices so constructed are intended to improve the agreement between earphone calibrations and their performance on human ears. A sequence of measurements and analysis is described for establishing that the ear simulator meets acoustic impedance specifications. The results of the measurements serve as a basis for accepting an ear simulator of this type as a standard device for calibrating earphones. Most laboratories have instruments needed to record earphone responses with ear simulators. These can be used to make the necessary impedance measurements.
