Can the sonographer alter the listening time?

Explanation:
Listening time is the duration over which the ultrasound system samples and lets you listen to the Doppler signal. The sonographer can adjust this time window to suit the study, extending it when you want to capture more cardiac cycles or faint, intermittent, or low-velocity flow, and shortening it when you need a quicker check. This control is a standard feature of ultrasound equipment, so being able to alter listening time is expected and appropriate. The other options imply limitations that don’t reflect how the equipment is used in practice.
