Introduction In this lab you will investigate sound waves and their properties using the WAVEPORT software (PASCO scientiFc). Using WAVEPORT you will modify the pre-deFned tones, investigate interference phenomena, and musical beats. You will also investigate the principle of superposition by seeing what results from adding two waves together. Experimental Procedure On the computer, double click the DataStudio icon. ±rom the Welcome to DataStudio window click on the Create Experiment icon. The Sound Capture window opens and the Sound Analyzer display opens. Display Setup: In the Displays list, double click on "Sound Creator" to open a Sound Creator display. Note: The Amplitude Tool and Period view are set by default. If you already have a Sound Creator display open and these tools are not showing, open the Settings dialog, select "Show Amplitude Tool" and "Period View" and click OK. Double click in the white space of the Sound Creator display to open the Settings dialog. In the Tones tab of the Settings dialog, click to place a check in the box next to "Show ±requency Buttons" and click the OK button. Note: If the Pitch Tool is not shown in your display, reopen the Settings dialog, click on the Tones tab, and click in the box next to "Show Pitch Tool." To turn on sound, click on the Speaker Tool. To turn off sound, click on the Speaker Tool again. Procedure: 1. In the open Sound Creator display, click on the Speaker Tool. 2. Hover your mouse over the Amplitude Tool and drag up (to increase) and down (to decrease) the amplitude. 3. In the Sound Creator display, notice the frequency of the default wave in the red ±requency box. Click on the Speaker Tool. 4. Using your mouse, click on the Pitch Tool. Drag the mouse left to increase the frequency or right to decrease the frequency.
