IEC 711 Precision Artificial Ear Frequency Response Curve Tester for IEM with 6 Channel USB Sound Card, Ear Simulator/Coupler And 3.5MM Plug Extension Cable

About: Precision Artificial Ear the IEC 711 Precision Artificial Ear is a device used for measuring and testing the frequency response curve of in-ear monitors (IEMs). It consists of several components that work together to simulate the human ear impedance and capture the sound output. It is a best tool for manufacturers, audio engineers, and enthusiasts who want to assess the performance and quality of audio devices.

USB SOUND CARD: The USB sound card is compatible with 6-channel codes for analog playback. It transforms the analog audio signal from the Precision Artificial Ear into a digital format that can be utilized by a computer. However, it requires support from application software. In digital playback mode, only PCM audio from the R and L channels can be transmitted in a 5.1 channel format.

PRECISION EAR COUPLER: This simulator is specifically created to imitate the acoustic properties of an average human ear. By connecting the Precision Artificial Ear to the IEMs under examination, the ear simulator/coupler guarantees a suitable fit and consistent positioning. This setup enables precise measurements of the frequency response, supporting different types and sizes of IEMs. It covers the audible range of 20 Hz to 20 kHz.

3.5MM PLUG EXTENSION CABLE: The purpose of this cable is to establish a connection between the ear simulator/coupler and the sound card. One end of the cable features a 3.5mm plug that is inserted into the USB sound Card port (Front out), while the other end is connected to the ear coupler. The cable is constructed using top-notch conductors and connectors, ensuring minimal signal loss and interference.
