  "textContent": "In everyday life, designing spaces that both let air flow and absorb sound can be a tricky balancing act. Usually, materials that allow air to pass through—like vents—also let sound escape, making it hard to reduce noise effectively. Conversely, sound-absorbing materials like foam often block airflow, limiting their use in ventilated areas.",
