Subject + 听见 + Sound/Clause
The verb 听见 (tīngjiàn) means "to hear" in the sense of actually perceiving a sound, as opposed to 听 (to listen), which emphasizes the act of trying to hear. The complement 见 indicates successful perception. For example, 我听见有人说话 means "I heard someone talking," implying the sound was clearly perceived.
