Interaction of Low Frequency Sound

In the world today, Concert Halls for Symphony Orchestra and Choir are generally enclosed performance spaces' that are completely cut-off from the outside: Whether it's a time of daylight or moonlight, rain or shine, summer or winter, spring or autumn, the environment within remains the same all the time. I asked the question: What if a concert hall offers views outside?' To be more specific, the question is: What if a concert hall offers views outside through the use of glass, along with other building materials, despite the fact that glass offers lower reflectivity and lower transmission loss for lower frequencies of sound, compared to certain other materials?' Hence the title: Interaction of Low Frequency Sound with Glass and other Building Materials in the Design of a Concert Hall for Symphony Orchestra and Choir.
