Auditory Perception Completion I

The auditory analog is demonstrated by Al Bregman with sinusoids and noise.

Part of signal A is replaced with silence then with signal B.

**Figure 9:** Replacing a gap with signal B can create preception of completion (continuity).

If signal B is loud enough, signal A appears to continue behind it.

This effect occurs when neural activity during B includes activity very similar to what would normally occur during A.
