You can easily recognize the meaning of 'Membran' (membrane) from context. In biological or medical texts, it refers to a thin skin or layer, e.g. 'Zellmembran' (cell membrane). In technical contexts, it means a vibrating disc, e.g. in a 'Lautsprecher' (speaker).
Jede lebende Zelle ist von einer Membran umgeben.
Every living cell is surrounded by a membrane.
'Membran' (membrane) is an internationally used technical term from science and technology. It comes from Latin and is therefore used in a similar form in many languages.
Für diese spezielle Filterung benötigen wir eine synthetische Membran.
For this special filtration, we need a synthetic membrane.
In a biological context, the membrane is often described with the adjective 'durchlässig' (permeable). An important property is whether it is permeable to certain substances or not.
Diese Membran ist nur für Wasser durchlässig.
This membrane is permeable only to water.
In a technical context, the central verb is 'schwingen' (to vibrate). The membrane in a speaker or microphone produces or receives sound by vibrating.
Wenn du die Musik lauter drehst, schwingt die Membran des Lautsprechers stärker.
When you turn the music up, the speaker's membrane vibrates more strongly.
