Psychoacoustic Mechanisms & Sensory Adaptation

1. Loss of Early Reflection Cues

The human brain constantly processes microsecond wall bounce delays (early reflections) to build an internal 3D spatial map. When absorption α approach 1.0, these reflection cues collapse to zero, creating an auditory void.

2. Vestibular System Disorientation

Without auditory spatial boundaries, the inner ear vestibular system experiences a sensory disconnect with visual inputs. This perceptual conflict frequently induces dizziness, loss of balance, and mild motion sickness within minutes.

3. Physiological Unmasking

In standard rooms, ambient sound masks biological noise. In hyper-quiet chambers (-9.4 dBA), the brain turns up its auditory gain, revealing the mechanical pumping of heart valves, air turbulence in the lungs, and auditory nerve spontaneous firing.
