Non-destructive impulse response technique was tested on two melon varieties ‘Zard-Eyvanekey’ and ‘Sousky-Sabz’ in five different stages of ripening. Resonance frequency and sound pressure level SPL from the impulse response were compared with mass, elastic modulus, soluble solids contents TSS and sensory evaluation. Among acoustic and destructive parameters, resonance frequency is an indicator to distinguish of different maturity stage of the melon in both varieties. The sound pressure level SPL was not a reliable parameter to evaluate melon ripeness. It was established that the impulse response technique is useful to decide fruit maturity stage and appropriate harvest time.
