Measurement of acoustic resonance width via the inverse Fourier transform of the Breit-Wigner form

Measurement of acoustic resonance width via the inverse Fourier transform of the Breit-Wigner form

The characteristics of the acoustic resonances of an elastic shell are obtained via the Fourier transform of the whole scattered signal and the inverse Fourier transform of a narrow frequency band in the vicinity of a resonance frequency.
