首楞嚴義疏注經 3.105

3.105

破聲來耳處也。初二句牒，如我下破。初舉喻，佛，音聲也。城，耳根也。林，鐘鼓也。此聲下例破。聲既來汝耳邊，此聲已離鐘鼓，只合汝自獨聞，不合他人亦聽；今且不爾，一切皆聞，應知聲無來往。

This refutes sound coming to the ear's place. The first two sentences take up [the view]; from 'it would be like me' downward refutes it. First, adducing an analogy: the Buddha is the sound; the city is the ear faculty; the grove is the bell and drum. From 'this sound' downward refutes by analogy. Since the sound has come to the side of your ear, this sound has already left the bell and drum, and it would only be fitting for you alone to hear it, and not fitting for others to listen to it as well; now it is not so, and everyone hears it; one should know that sound has no coming or going.
