Longest sound made by a person

A human being can make a long sound by emitting air through the vocal cords. The duration of the sound will depend on various factors, such as vocal technique, lung capacity, and physical endurance.

To produce a prolonged sound, the singer or sound emitter must use proper breathing techniques and control the airflow through the muscles of the throat and vocal cords. This may involve using different vocal techniques, such as singing, speaking, or emitting guttural or nasal sounds.

A human's ability to make a long sound also depends on their lung capacity and physical endurance, as maintaining a prolonged sound requires a good reserve of air and the ability to maintain proper muscle tension for an extended period of time.
