About This Product

■Summary

HMS II.5 is a full-band dummy head dedicated to measuring voice and audio quality in the transmit direction. It is especially suitable for testing hands-free systems, smart speakers, and other calling devices that are used far from the ear. The shape and acoustic characteristics of this head and torso simulator comply with ITU-T Recommendation P.58, and reproduce all structures that affect the acoustics of the human body. HMS II.5 only supports transmit direction measurements and is equipped with a full-band low distortion 2-way mouth speaker. No pseudo ears are installed. The simulated mouse reproduces the full spectrum of the human voice and is capable of narrowband, wideband, superwideband, and fullband measurements. HMS II.5 features a newly introduced module concept. This concept is common to all HEAD acoustics dummy heads in the call and audio test field. In the future, the same dummy head will be able to handle different applications. Quickly and easily replace the artificial ear and pinna to suit the measurement task.

■Highlights

・HMS II.5 is ideal for full-band measurement in the transmitting direction of audio and communication devices used at a distance from the ear. ・The shape and acoustic characteristics of the dummy head comply with ITU-T recommendation P.58. - Modular concept allows HMS II.5 to be quickly and easily adapted to the measurement task.

■Speech quality and audio quality measurement in the sending direction

・In-vehicle applications such as hands-free terminals, in-car calling (ICC) systems, infotainment systems, and emergency call (eCall) devices ・Smart home devices with voice control such as smart speakers and IoT devices ・Conference phone, hands-free device
