Final answer:
A manometer is used as a visual guide to help adapt consistent airflow in flow phonation.
Step-by-step explanation:
When it comes to flow phonation, a visual guide that helps adapt consistent airflow is a manometer. A manometer measures the pressure difference between two points in a fluid. In the case of flow phonation, a manometer can be used to monitor the airflow and ensure it remains consistent.
For example, if a person is using flow phonation techniques to produce a sustained musical note, they can connect a manometer to their breathing apparatus or instrument. By observing the manometer reading, they can adjust their breath control to maintain a steady airflow and produce a consistent sound.
Overall, a manometer serves as a visual feedback tool in flow phonation, helping individuals achieve and maintain the desired level of airflow for optimal vocal performance or musical expression.
