"Sound Spheres" at Mineral Baths

We went to the baths last week and were totally fascinated by these concrete half spheres that project sound. There are two quite a distance apart. If you whisper into one, it is projected loudly to the other as if there is a speaker. We are curious what this is called and who it works. Our grandson loved it!
