Simulated Ear KABR E370

The KABR E370 Simulated Ear mimics the acoustic characteristics of the human ear canal. It is a device that enables acoustic measurement by simulating the coupling between in-ear headphones and the human ear through inserting a catheter into an ear mold.

The pressure-field artificial ear is an ear simulator that mimics the way an in-ear headphone catheter is inserted into the ear canal or auricle. It simulates the coupling between headphones and the human ear to measure the acoustic performance of headphones.

The E370 includes a pressure-field artificial ear cavity and a preamplifier. As a pre-polarized pressure-field measurement microphone kit, it is specifically designed for audio production line testing of in-ear headphone products.

The classic configuration of "E370 Artificial Ear + Signal Conditioner + Artificial Mouth" has become the standard configuration for most domestic and international in-ear headphone audio testing systems due to its extremely high stability.
