The mark consists of the distinctive sound of a single deep breath, lasting approximately 4-6 seconds, characterized by an inhalation followed by a brief pause and subsequent exhalation of similar length. The inhalation begins with a soft 'uhhhhh' sound that gradually increases in volume and intensity as air is steadily drawn in, deepening over approximately 2-3 seconds. This inhalation phase has a smooth, continuous quality with a subtle rising pitch that peaks as the lungs fill with air, creating a rhythmic and deliberate auditory pattern that evokes a sense of calm and focus. After a brief pause, the exhalation is marked by a slow and steady release of air, beginning with a soft, audible 'huuh' sound, followed by a gentle, continuous 'hoosh' that lasts approximately 2-3 seconds. The exhalation gradually decreases in volume and fades out at the end, enhancing the calming effect and evoking a sense of relaxation and mindfulness. The sound as a whole is unique due to its controlled, rhythmic, and soothing nature, distinguishable from regular breathing sounds by its deliberate pace and clear, smooth airflow.
