This questions depends on some other factors, but in our internal testing, the DK6 system at full settings runs at about 60db max or equivalent to a quiet office setting. Video link of the test here. Other considerations that matter is how high your settings are set in our motion software and what environment is the DK sitting in. High settings, specially road and engine vibrations will resonate a lot more than lower settings with smoothing applied. Additionally, hollow floors, walls and thinner structures will reverberate more than solid concrete floors and walls, which tend to absorb sound much more. In addition installing gym mats or floor pucks underneath the actuator feet can dampen a majority of the sound and reverberation coming from the haptic system.
