| Research Abstract |
Musical-sand is an interesting coastal sand which makes a beautiful sound by shuffling ones feet. This musical-sand is very sensitive to environmental changes and instantaneously stops its sound if mixed with just a little dust. This research described valuable musical-sand in the practical view point how to keep it in good condition and to restore its original state.
Conclusions obtained from this research are summarized as follows ;
(1) Japanese musical-sand can be expressed as a quartz particle having the average size of more than 0.3MM, the quartz content more than 60% and the larger the quartz particle is and the more the quartz contents is the more insensitive and the lower the sound is.
(2) The practical application of this research to restore of Japanese musical-sand beachs were introduced for the two cases. Especially notable that the success of using artificial musical-sand by the investigators where it is not only the same as an actual sand particle but also to make a good sound is very effective to remedy contaminated musical-sand beach is possible.
