Usage tips
Compound word
The word 'Hörsaal' (lecture hall) is a compound of the verb 'hören' (to hear/listen) and the noun 'der Saal' (hall). So it literally describes a hall where people listen, typically to a lecture.
EXAMPLE
Die Akustik in diesem Hörsaal ist leider sehr schlecht.
Unfortunately, the acoustics in this lecture hall are very bad.
Correct preposition
Pay attention to the difference with the preposition 'in'. When describing movement, use the accusative: 'in den Hörsaal gehen' (to go into the lecture hall). When describing a location, use the dative: 'im Hörsaal sitzen' (to sit in the lecture hall).
EXAMPLE
Die Studierenden strömten in den Hörsaal.
The students streamed into the lecture hall.
Typical collocations
'Hörsaal' (lecture hall) is used almost exclusively in the context of universities and colleges. Typical adjectives are 'überfüllt' (overcrowded), 'leer' (empty), or 'modern' (modern), and typical verbs are 'betreten' (to enter), 'verlassen' (to leave), or 'eine Vorlesung halten' (to give a lecture).
EXAMPLE

Hörsaal vs Klassenzimmer
classroom
'Klassenzimmer' and 'Hörsaal' are both rooms for learning and teaching. A 'Klassenzimmer' is found in a school; that is where a school class has lessons. It is usually smaller and equipped with desks, chairs, and a board. A 'Hörsaal' belongs to a university or college and is often large, because many students attend a lecture there. The words can be confused because both are teaching rooms. For school, you say 'Klassenzimmer'; for university, you usually say 'Hörsaal'.
Hörsaal
Der Hörsaal ist heute voll, weil die Vorlesung sehr beliebt ist.
The lecture hall is full today because the lecture is very popular.
Klassenzimmer
Nach der Pause gehen die Kinder zurück ins Klassenzimmer.
After the break, the children go back to the classroom.
