when we hear the human voice, we instinctively want to listen and hopes of understanding it. even when the speaker is searching for the right words to say. even when all we hear is yelling, or crying, or singing… that’s because the human voice resonates differently from anything else in the world. that’s why we can hear the singers voice over the sound of a full orchestra.. we will always hear that singer no matter what else surrounds it. 🙂
