1 Physics 198 Laboratory 7 My name: Lab Partner (s): HELMHOLTZ RESONATOR Well over a hundred years ago H. von Helmholtz used this device to analyze musical sounds. Although modern electronics, such as the apparatus on your table, makes this much easier, the basic physics of the resonator is of prime importance, e.g., for understanding the A 0 resonance of string instrument bodies. Flute players do very well in this lab. Equipment: About 10-20 jugs and bottles with fairly distinct neck and main volumes and several graduated cylinders of up to several hundred milliliters. There should be a bottle of spray to help disinfect bottles before use and each bottle should be washed after use. Each table should have a meter stick, a Dell Optiplex 620 Computer equipped with SpectraPlus sound analysis software, USB audio interface box (M-Audio, FastTrack) connected to a good microphone (Shure MD58). There is now a single printer connected to the computers via a wireless network. Headphones are also shown below, but are not used in this lab. There should be graph paper available in the room. Settings: The SpectraPlus Options “Device” input should be set to “Fast-Track.” The vertical scaling should be linear and the horizontal also linear, and the “Settings” (under the options menu) should be default, and the mode should be real time. The “mic level” knob should be all the way up (CW) and the “mix” should be CCW (input).
