聴覚

1. Origins, structure, and basic meaning

• Structure: 聴覚 (ちょうかく) is the sensory capacity to perceive sound. It appears as a means of judgment and a compared trait.
• Basic usage: Hearing alone determines someone's position; an exhibit compares hearing in humans and animals.

2. Common pitfalls and similar expressions

• Sense relied on for location and sensory difference across species
  • 聴覚だけを頼りに restricts the sense used; 聴覚の違い defines a comparison. The word is the faculty, not the ear organ itself.
