We study the spontaneous emission in a fourlevel atomic system driven by three coupled fields. We have demonstrated the existence of electromagnetically induced transparency (EIT) with a set of suitable parameters, and we find that the light levels of the drive fields are as weak as that of the spontaneous emission with the EIT.
