No, blind people don't necessarily hear better in the general sense. However, research suggests that they may exhibit enhanced auditory processing in certain specific areas.
Enhanced Auditory Processing in Blind Individuals
While popular belief might suggest superior hearing in blind individuals, the reality is more nuanced. Studies show that blind people often demonstrate improved processing of non-spatial auditory information. This means they might be better at tasks involving identifying sounds or distinguishing between different sounds without needing to locate the sound's source. This enhanced ability is a specific skill, not a general improvement in hearing acuity.

Nonspatial Auditory Processing: Blind individuals often excel at tasks requiring the discrimination of sounds based on their qualities (pitch, timbre, etc.), rather than their location.
-
Trade-off: It's important to note that this enhancement in non-spatial auditory processing often comes with a trade-off. Their ability to pinpoint the location of a sound (spatial auditory processing) might be less accurate compared to sighted individuals.
In summary, while blind individuals may possess certain specialized auditory advantages, this doesn't translate to overall better hearing. Their enhanced abilities are concentrated in specific areas of auditory perception. Their improved non-spatial hearing is a fascinating adaptation, but not a blanket improvement in hearing across the board.
Overall, although blind individuals possess acoustic enhancements, these abilities are specific as they appear to demonstrate sufficient or even improved nonspatial auditory processing, but a trade-off occurs between specific spatial auditory processes.
