| CAD: For the design of the housing i used Autocad R14. It is easy to use and, for a PC-system, it has a great functionallity - it is also able to export the design drawings in different formats f.e. *.wmf. |

Measurement Software:
As a frequency generator i used the program audioTester V1.4b (in combination with the soundcard of my notebook). A direct comparison with the frequency generated by the Fluke- frequencygenerator shows a good accuracy for the combination soundcard+audiotester. I used the frequency generator only to measure and calculate the system impedance and damping factor. For sound pressure measurements the wobbled signal from my Technics- Terzanalyser give better and more practical results in a real living room where you listen to the music. |
