HRT I is a high-precision remote-controlled turntable. It allows for the rotation of the measurement target device to a specified angle, enabling direction-dependent acoustic measurements.
HRT I is a high-precision remote-controlled turntable developed by HEAD acoustics. It enables direction-dependent acoustic measurements by rotating the device under test to a user-specified angle within the measurement field. Its operation can be fully automated via HEAD acoustics' call analysis system ACQUA, MATLAB, or Python. The HRT I can also be manually operated using the front buttons or the included software tool RC-HRT I. The robust design of the turntable ensures a load capacity of up to 100 kg. With a maximum rotational torque of 28 Nm and a reproducibility of 0.02°, precise angling of the object under test is achievable. When idle, the turntable generates minimal noise, creating a quiet environment suitable for acoustic measurements.

| Turntable HRT I | Directionality is important for the performance of products that emit or receive sound. When testing these devices, it is necessary to measure while changing directions, but manually positioning them is difficult. The HRT I is a turntable designed to perform this testing remotely and automatically. |
