← Nature & AnimalsWhich outcome occurs when bat vocalizations weaken upon target approach?
A)Larynx overheating and permanent damage
B)Increased sensory pathway signal processing
C)Auditory acuity diminishes to avoid overload✓
D)Target detail loss increases near-field
💡 Explanation
Auditory acuity decreases near a target because neural saturation protects against overstimulation during intense echoes using 'gain desensitization'. This mechanism prioritizes overall sound processing, therefore, preventing auditory damage, rather than clarifying nearby details.
