The word 嗓音 is formed by combining two characters, each contributing a layer of meaning to create a new, specific concept. The first character, 嗓 (sǎng), directly represents the throat, the physical organ that produces sound. The second, 音 (yīn), means sound or tone. When placed together, they conceptually merge to depict "the sound that originates from the throat", thereby forming the complete idea of a person's voice in terms of its timbre or quality. It is a direct visual and semantic synthesis of the source and its product.
