Head movements, left and right input and output levels, and input and output ILDs plots, for a speech-shaped noise input at 60 dB SPL (left ear). Each column displays a different rotational velocity. Column one (left) shows 30°s-1, column two (middle) 60°s-1, and column three (right) 120°s-1. Row one shows head movement, row two shows the input (grey) and output (black) level of the device at the left ear, row three shows the same for the right ear, and row four shows the input (grey) and output (black) ILDs. The areas of the plots bounded by the dashed lines show the period of rotational movement.
