The three-rattle angklung is a traditional musical instrument made of bamboo. The objective of this research is to observe the unique sound characteristics of the three-rattle angklung. The sound characteristics data can be used for defining digital sound of angklung to be played in a digital synthesizer. One set of angklung from the big size C 5 to the small size C 6 is recorded and analyzed in terms of the frequency contents. The sound characteristics of angklung are represented by four dominant frequency contents and the corresponding relative amplitudes of each rattle bamboo tube. This paper also introduces an equation model to predict the sound produced by the bamboo of the three-rattle angklung. This research reveals that bamboo rattles 2 and 3 produce the fundamental note, and bamboo rattle 1 generates a higher octave with the same note. Each bamboo rattle produces fundamental frequency note, its harmonics, and overtones. It is also found that three-rattle angklung can produce an accurate frequency almost in every note.

This paper presents the differences of anthropometric data between Malaysian, Chinese, Korean, Japanese, Taiwanese, North American, North African, South Indian, Portuguese and Australian, which can be use in anthropometric test dummy (ATD) and the computational modelling of ATD. The available anthropometric data of stature, sitting height and sitting knee height for male and female are analyzed by weighting them according to their ranking in the corresponding parameters and presented in bar chart. It is found that Australian male and female have the biggest body posture compared with others. The results also indicate that females in Australia, North Africa and South India, when the three parameters are considered, they have bigger posture than male. For the computational model, hybrid modelling combine finite elements and rigid bodies can be an alternative approach.
