Answer 1

.you can lose up to 90% of the nerve fibers in your cochlea without losing the ability to detect sounds in calm environments, but just background noise is enough to reduce your hearing ability considerably. Therefore the hair cells in the inner ear may be completely intact, but hearing may still disappear if the synapse nerve is damaged.
