Task: Audiometry

Key words: sound intensity, level of intensity, decibel unit, hearing range


Measured values:

Frequency (Hz)

              Level of the intensity - left ear [     ]

                                                       Level of the intensity - right ear [     ]

Conclusion:












Task: Doppler ultrasonic flowmeter

Key words: ultrasound, doppler effect, systole, diastole


(You will measure the rate of blood flow - velocity - over time in this task. The flow rate changes
as the heart muscle contracts = systole and dilates=diastole)


Measured values:


                 Left hand -velocity [        ]

                                               Right hand- velocity [        ]
