HRR I is a motorized rotating reflector. It allows to dynamically change the acoustic coupling between loudspeaker and microphones in arbitrary handsfree communication scenarios and such the realization of time-variant echo paths. As such, HRR I is compliant with the Recommendations ITU-T P.1100, P.1110 and P.1120 regarding measurements of echo attenuation performance for in-vehicle hands-free systems. |
Typical applications for testing with HRR I are echo-performance tests for all types of smart speakers and other smart home devices, conferencing devices and mobile devices with hands-free telephony function. |
HRR I operates noise-free and with high precision, creating ideal conditions for uninhibited and fully repeatable tests and measurements. |
