Description
The Bruel & Kjaer 4185 Ear Simulator is a highly accurate device used in the fields of acoustics and audiology to imitate the behavior of the human ear. Its purpose is to precisely measure and duplicate the acoustic properties of the ear canal, enabling precise examination and calibration of audio equipment. This ear simulator comprises a microphone positioned at the entrance of a simulated ear canal, which closely resembles that of a real human ear. It is equipped with interchangeable ear tips to mimic different sizes and shapes of ear canals, allowing for versatile testing scenarios. The Bruel & Kjaer 4185 Ear Simulator is an essential tool for researchers, manufacturers, and audiologists, ensuring the precise assessment and advancement of audio devices and hearing aids.
