A Soundless Void

[Mercen-X]

If a person who is normally not deaf were to attempt to navigate say a cave system, but could not hear anything due to some odd phenomena (and could not produce sound either), would said person be disoriented, become lost, or even edge on madness in the case of prolonged lack of sound?

There’s probably been an unethical experiment or two on the matter that’s somewhere out there. You’ve just got to dig deeper.

It causes extreme anxiety for the person to be voided of sound when they are normally used to it. Though what usually happens when a person is placed into a location that absorbs most external sounds is that the person becomes painfully aware of how much noise our bodies make like the sound of breathing or their heart beat.

I imagine a person would panic from the lack of noise, but they could probably use other senses to make their way through a cave system, the only real issue would be judging height if they found a cliff or hole.

[Mercen-X]

That's true. Without the advantage of echo-location, judging depth or distance by sight alone can be unwieldy.

I wonder also if a person would begin to assume their situation was permanent, reminiscing not only on the melodies and joyful noises but succumbing to depression at realizing they might never again hear their own heartbeat much less anything else.
