隔音或游泳防耳朵進水的「耳塞」在英文裡叫什麼？答案是：
earplugs (因為一對是2個，所以通常都要加s)
另外加空白也可以： ear plugs
照慣例的英解：
a small piece of soft material such as wax, cotton or plastic which you put into your ear to keep out noise or water. (cambridge dictionary)
An earplug is a device that is meant to be inserted in the ear canal (外耳道) to protect the user's ears from loud noises or the intrusion of water, foreign bodies (異物、外來物), dust or excessive wind. (wikipedia)
我也找到有些產品上是寫 ear filters，但似乎是比較少見的用法。
