A study on acoustics of conch shell

摘要

The mechanism of generation of musical sound in conch shell excited by lip vibration is presented with reference to up-to-date literature on operation of wind instruments. The process of ‘mode-locking’ is indicated in the context of our observed spectrum. The spectrum of conch sound is explained with reference to the geometry of conch shell and its equivalence as a conical horn, where the nature of spectra fairly agrees with the theory.
