Echo location

You create a magical sound and use your magically enhanced senses to follow the echo of that sound 

you learn the layout of the environment around you within 30ft as part of this you learn the location of any traps/hidden passages or creatures and items within the area 

you do not learn any details about the creatures other than size and type (such as beast or humanoid) and you only learn its location in that moment it does not allow you to track the creatures movements
