看到篇文章说声音媒介是「最纯粹的交流系统」，用声音传递信息本质是分享声波的形状。

以下摘自文章：thereader.mitpress.mit.edu

大多数人类通过波进行交流这一事实本身可能并非偶然; 毕竟，波构成了最纯粹的交流系统，因为它们在不改变两个实体的结构或组成的情况下将信息从一个实体传递到另一个实体。它们穿过我们，又完好无损地离开我们，但它们允许我们解释它们瞬间振动所传递的信息，前提是我们有破解它的钥匙。「信息」（information）一词来源于拉丁词根 forma (shape) ，这绝非偶然：传递信息是指分享一个形状（To inform is to share a shape）。

The very fact that the majority of human communication takes place via waves may not be a casual fact; after all, waves constitute the purest system of communication since they transfer information from one entity to the other without changing the structure or the composition of the two entities. They travel through us and leave us intact, but they allow us to interpret the message borne by their momentary vibrations, provided that we have the key to decode it. It is not at all accidental that the term information is derived from the Latin root forma (shape): To inform is to share a shape.
