Abstract
The objective of this research was to study and develop equipment to measure the volume of mango based
on a technical acoustic resonance technique, namely that the resonance frequency that occurs in a
Helmholtz resonator varies with the volume of air in the resonator. This method was used to measure
nondestructively the volume of mango. The equation for volume prediction was derived from experiments by
using different sizes and positions of mangoes. The prediction equation was a linear relationship between the
volume of the mango and the resonance frequency. In addition, the experimental results showed that the
standard error of prediction was 9.41 and the bias was -11.59 cm3
