Acoustical studies on conch shells.

Abstract

Sound from blowing a conch shell is known for its tonal quality. Its use in many cultures is known. In Hindu culture, conch shell is blown on several auspicious occasions such as festivals, worship, and rituals. A conch shell can be modeled as a horn in its acoustical behavior. This work presents an acoustical study in terms of the spectral characteristics of the shell. The study also presents the influence of parameters such as placing hand in the mouth of the conch shell and the size of conch shell on the spectral characteristics.
