Abstract
Hollow heart is a problem quite specific to seedless watermelon, affecting to all varieties. Percentage of fruits affected range from nil to up to more than 50% of the fruits. The acoustic impulse response of 158 watermelons was measured using a prepolarized free-field microphone. After carrying out a fast Fourier transformation on the time signal of the generated sound several acoustic parameters were evaluated. Values of spectral density were significantly different between 'good watermelons' and 'hollow heart watermelons'.
