The noise in the shell increases along with the level of ambient noise in the surrounding area. The "ocean" is a lot louder in a noisy room where a multitude of sounds bounce around and mix together inside the shell. The level of noise we hear also depends on the angle and distance of the shell from the ear.
貝殼中的聲音會隨著周圍雜音的音量變大而增強。因此“海洋”的聲音在一個嘈雜的房間中聽來會更大。因為房間里多重復(fù)雜的聲音會在貝殼中來回激蕩、相互混雜。我們聽到聲音的大小同時也取決于貝殼與耳朵的角度及距離。
(短文節(jié)選,本篇始于：貝殼傳來海洋之音)
