請告訴我 「聲音產生回音，聽起來不清楚」 的英語！

・The sound is giving off feedback and is hard to hear.
・The sound is echoing and difficult to make out.
・The sound is screeching and it's challenging to discern.

The sound is giving off feedback and your voice is hard to hear during this online lesson.
「在這堂線上課程中，產生了回音，導致老師的聲音很難聽清楚。」

這個片語用來描述音響設備產生令人不舒服的雜音或回音，讓說話聲或音樂等變得難以聽清楚。特別是在現場音樂會、演講會、會議等場合，當麥克風或喇叭出現不適當的回饋聲（噪音）時，會用這個表達來說明這個問題。

I'm having a hard time during this online lesson because the sound is echoing and difficult to make out.
「這堂線上課程中，聲音有回音，讓我很難理解老師在說什麼。」

The sound is screeching and it's challenging to discern during this online lesson. Your voice is echoing, making it difficult to hear clearly.
「在這堂線上課程中，聲音有刺耳的雜音，讓我很難聽清楚。老師的聲音有回音，聽起來不夠清楚。」

「The sound is echoing and difficult to make out」這句話用於聲音有回音，導致內容難以理解的情況。例如，在寬敞的禮堂裡，從遠處聽到的演講就可以用這句話來形容。「The sound is screeching and it's challenging to discern」則表示聲音很刺耳，讓人難以掌握內容。例如，當麥克風產生回饋聲或機器發出刺耳噪音時，會用這句話來描述。
