1F推:其實我這說法也是在相對性的，半無響室測試條件下環境噪音09/17 10:48
2F→:非常低，低到耳機只要有開，麥克風一定先收到耳機的聲音，09/17 10:49
3F→:AJ兄如果也是會看頻譜，我這個說法與其說耳道傷害大，不如09/17 10:49
4F→:說條件在同db值的情況下，耳道式的耳機因為阻絕了過多的09/17 10:50
5F→:廣頻噪音，使得累計計算的tone會衝高，容易形成尖銳的聲音09/17 10:51
6F推:，當然這樣的說法是先過濾掉每個使用者的習慣問題，09/17 10:54
7F→:倘若我們預設由於配戴耳道式耳機不會聽到太多廣頻的噪音，09/17 10:54
8F→:因此使用者無須調到過大的音量，或許統計數據上會出現因為09/17 10:55
9F→:耳道式耳機使用者長期接受低聲壓的刺激，反倒受到比較少的09/17 10:56
10F→:聽覺傷害，當然了，聲壓跟TONE(高頻尖銳音)都是傷害聽神經09/17 10:56
11F→:的主要因素，只是一般在客戶規格上，都是以tone為主考量。09/17 10:57
