| Jan 11, 2016 at 2:54 | comment | added | bandybabboon | Ross is right you would have to do some comparison tests by measuring the performance with cold air, perhaps by biting an ice cube first, and objectively by using mechanical lungs that send the same breath of cold air for every measurement. You may find it interesting to use christoph-lauer.de/sonogram freeware to see various wigner ville and fourrier graphs and harmonics distributions from the microphone. newt.phys.unsw.edu.au/jw/brassacoustics.html | |
| Jan 11, 2016 at 2:52 | comment | added | Ernie | How do you intend to determine the specific heat capacities of different types of wood? Specific heat of wood in general is about 1.76 joules/gram∘C. Do you have a table of specific heats for different types of wood? | |
| Jan 11, 2016 at 1:58 | comment | added | Ross Millikan | The speed of sound in air increases as the square root of the absolute temperature. I suspect the heat buildup inside the instrument is much more due to the warm air supplied by the musician than due to acoustic losses inside the instrument. The amount of energy in sound waves is quite small, so it is hard to get any reasonable heating that way. Transferring the heat to the wall will reduce the effect even more as the wall is so much more massive than the air. | |
