Review of Lung Sounds

This technically-demanding page was authored for and cross-checked using Netscape 3.01 with Shockwave w/Streaming audio, LiveAudio and RealAudio plugins installed. You may not be able to hear the sounds without similar software and plugins.
You can do a quick check - click here to test audio to see that everything is in place.
On student machines in the MDLs or Resource Room, there is a chance that the last user disabled sound or turned the volume "way down". A simple control-panel sound adjustment may be all that is needed.
