This drill will teach you to detect the difference between a third heart sound and a split second heart sound.
We will play a split second heart sound without a third heart sound and then an unsplit second heart sound with a third heart sound. Note that the sound of the third heart sound is lower in pitch than the second heart sound.
When you are confident that you can detect the difference, move on to the test. In the test we will play cycles randomly and ask you to tell which is which.
