On the left side of the synchronous measurements set-up, it is visible that the phonographic (acoustic) sensor head is attached to the Fetaphon2000 monitor and its data are transferred via Bluetooth to a laptop. On the right side, the sonograph sensor head is attached to the ultrasound monitor used for validation only. The ultrasound measurements are recorded by a video recorder.
