Just to supplement what Eugene stated, yes, you can indeed start your own meeting to test. You can also go to “Audio Options” by clicking the arrow next to the microphone icon in the lower left, where you can view and, if needed, alter your own speaker and mic settings. This window includes a test speaker icon, a test microphone icon (that records a snippet of your voice, and plays it back to you immediately) as well as a visual microphone meter.
If you or your students are having trouble with audio input or output, please take a look at this Zoom help article which gives a few more ways to test.
