Over the last year, I have been looking at the acoustics of the Charango, a small stringed instrument from the Andean region of South America, using a Polytec Laser Vibrometer. Now that this is all done (got a distinction in it by the way) I got permission to use the equipment for around 5 hours in one day to try and take some measurements of melodeon reeds. Unfortunately I did have only 5 hours and didn’t have much equipment other than the vibrometer, so I was limited in what I could do. In addition, I don’t have MATLAB on this computer, so I am limited in the analysis as well. I hope however that the following is of interest to those intrigued by how the box works. I haven’t concluded anything game-changing, however I hope that this study shows that within 24 hours, interesting experiments can be carried out. If there is anyone out there attached to a research centre who is interested in studying these instruments then please get in touch with me – I would love to hear from you. This is not a formal report, this is not a formal study and nothing should be taken to be conclusive. I think however that it can be considered to be indicative. Continue reading →
