Conch has a long history as a musical instrument and has been one of the Buddhist instruments since ancient times. In addition to being used as a ritual instrument in Buddhist monasteries, in nunneries in Tibetan areas, blow shells are used to pay homage to the deceased. It is also widely circulated in the Han nationality area. In the Zhoushan gongs and drums in the folk instrumental music ensemble in eastern Zhejiang, the conch is used as a colorful musical instrument. In coastal areas such as Guangdong, Guangxi, and Fujian, the folk often convene mass gatherings by playing conch shells.

Listening to the sound of the sea with a conch is a romantic saying. The scientific explanation is that the shape of the inside of the shell is curved, and it is filled with air, so when you are in a noisy place, these noises make the air in the shell vibrate, so you stick the conch into the shell. You will hear the sound of the tide. When you're in a particularly quiet room, there's very little sound coming from around you, and the volume is too low to vibrate the air in the shell, so you don't hear the tide when you put the shell to your ear. sound.

Another theory is that the structure of the shell allows it to resonate to amplify certain frequencies of sound in the environment, such as the sound of human blood flowing. So put the shell to your ear, and most of what you hear is the sound of your blood boiling from the depths of your heart.
