The higher hearing abilities of groups S – XL compared to those of group XS are a clear consequence of the development of the chain of Weberian ossicles.
Even though prey insects usually have much higher hearing thresholds than bats, the prey's detection range is much longer than the bat's, because the prey detects the outgoing echolocation call, while the bat detects the weak reflected prey echo [25].
However, it was found that lower fluid intelligence scores were related to higher hearing thresholds.
We found, consistent with other hearing studies, that males have higher hearing thresholds across the majority of frequencies (3, 4, 6, and 8 kHz [ p < 0.001]) than females.
Having otorrhea in the first year of life resulted in higher hearing thresholds at 4 kHz, 6 kHz, and 8 kHz at 61 to 63 years (Table 2).
These results suggest that those people with higher hearing disability acceptance had less self-reported hearing disability, fewer self-reported symptoms of anxiety and depression and lower readiness to change.
