"Ta osoba váš stroj neslyší."

Translation: That person does not hear your machine.

[Linda_Turner_22]

That person cannot hear your machine? This sounds more natural to me.

[VladaFu]

Both are accepted. This is a difference between BrE and AmE.

[Zeidinho]

Is it fine to say: Ta osaba neslyší vás stroj?

[AgnusOinas]

Of course. But you have two typos there: Ta osoba neslyší váš stroj. ("vás" is a different word)
