if it is big enough and the correct shape, it will act like a big reflector lens and magnify and redirect the sound, it may need to be that high to give the appropriate redirection and still give the desired shape on the outsideMaybe it is, but it's a weird science. Internal shapes, baffles etc to channel noice.
It's like if your under the dome at St Pauls you can hear something spoken in a very low voice on the opposite side. Daft comparison I know.
@Jacko93 knows a bit more a out what was done with the design for acoustics.
