The "sound of relief" is often described as a "sigh of relief," which is a slow, noisy breath that expresses happiness or relaxation that something unpleasant has not happened or has ended. It signifies a feeling of comfort and release from stress or worry. On the other hand, "wistfulness" typically refers to a sound or expression that conveys a gentle, longing, or vaguely sad feeling, often tinged with nostalgia or a sense of yearning for something lost or out of reach. So, the "sound of relief" is more about a release of tension and happiness that a bad outcome was avoided, while "wistfulness" carries a softer, more melancholy tone of longing or reflective sadness. In summary:
- Sound of relief = sigh of relief, a breath expressing happiness or comfort after worry.
- Wistfulness = a gentle, longing, or nostalgic sound, often with a slightly sad or reflective quality.
