Experimental methods are presented for measuring the impulse response of brass wind instruments. The impulse response values are used to calculate the frequency response and reconstruct the instrument's shape. Comparisons between the measured values and theoretical values predicted by discrete lossy models make it possible to localize the areas of the instrument in which the models are inaccurate. The solution to the inverse problem is very sensitive and therefore not applicable to experimental data. However, it could be used in designing acoustic instruments.
