The HMS V digital artificial head combines cutting-edge technology, high flexibility, and ease of use. With its Dual ADC technology (two parallel analog-to-digital converters), HMS V covers the entire audible dynamic range, rendering measuring range changes obsolete.
With HMS V, you perform binaural equalization immediately during the measurement. The headphone jack enables playback or monitoring during measurement using HEAD acoustics headphones. You hear the recordings precisely as if you had been in the original sound field. The HMS V integrates seamlessly into HEADlab systems as a binaural sensor. It constitutes a comprehensive measurement system combined with other artificial heads or linked to other devices, such as the acoustic camera HEAD VISOR or the frontend SQuadriga III. A PC with the ArtemiS SUITE recorder software connected via USB or LAN takes over control in front-end mode. Integrating an additional HEADlab module allows you to adapt the system flexibly to specific measurement tasks.
HMS V even offers convenient standalone recordings (SAR) with internal memory for the signal data and a powerful, high-capacity battery. You can increase the autonomous runtime with a labPWR battery module and USB memory. During SAR, you configure and control HMS V using an intuitive web interface that runs on a smartphone, tablet, or PC connected wirelessly or via cable.
