Learn Hardcore Polish: Teraz wyraźnie słychać muzykę w salonie. - Now you can clearly hear music in the living room.

Słychać is a special, impersonal verb form. Literally it means something like “(it) can be heard” or “one hears”, without saying who hears it.

Polish: Teraz wyraźnie słychać muzykę w salonie.
Very literal meaning: “Now (it) is clearly heard: the music in the living room.”
Natural English: “Now you can clearly hear music in the living room.” / “The music in the living room can be clearly heard now.”

Key points:

There is no subject (no “it”, “they”, “we”) expressed.
You use słychać + object (accusative) for “something can be heard / is audible”:
- Słychać muzykę. – Music can be heard.
- Słychać dzieci na podwórku. – You can hear children in the yard.

If you want a normal verb with a subject, you use słyszeć:

Słyszę muzykę. – I hear music.
Słyszymy muzykę w salonie. – We hear music in the living room.

Using jest słyszana (is heard) is grammatically possible but sounds formal or technical; in normal speech, słychać is much more common.

Why is it muzykę, not muzyka?
