Vernier+Microphone

Using the Tool:
1) Locate both Microphone and LabQuest. The connecting cable is built in to the microphone, and the Channel ports on top of the LabQuest (labelled CH1-4) will all fit the connector. 2) The microphone is intended to collect and display waveforms created by sound. It does this by measuring the pressure.



3) Press the Power button on the upper left corner of the device. You have to press firmly, and the button will be backlit in blue once it’s been powered on. The screen should also illuminate at this time.

4) There is a small stylus on the back of the LabQuest to retrieve. It will help you interface with the LabQuest, since the buttons can be difficult to press otherwise.

5) The main screens that will be useful are the first tab, “Sensors,” and the second “Graph.”

6) Sensors will show the sound pressure represented as a number. Ambient room noise seems to be around 2.8.

7) Graph, one must press and briefly hold the “play” button on the bottom left of the LabQuest screen. This will capture a snippet of sound, which will then be displayed as a soundwave on the Graph page.

8) “Table,” the third tab, shows data collected thus in a table form instead of graphed. The fifth tab is a simple spot for notes. 9) To download your data, the LabQuest must be plugged in to a computer that has both the LabQuest drivers and Logger Lite installed. This will enable you to work with the collected data in a lab environment. This is particularly useful to our purposes because we have only the one LabQuest and several computers with the Logger Lite software.
