@Lou Ann: No, both sentences are active voice.
Passive voice: Los rostros de las mujeres en Medio Oriente son tapados. (Which sounds horrible and not clear btw.)
The difference is the
pronominal form of the verb:
taparse vs.
tapar.
(Not all the verbs can be like this though.)
Ellas
se tapan el rostro = ellas
tapan su rostro.
