As an experiment I recorded the space and then listened to the recording after noting my initial impressions. What it is most obvious is the lack of selective focus that our ears and brains have naturally (it is surmised that losing this ability is a primary reason for being 'hard of hearing' in older people, rather than an actual loss in the ability to hear sound in general). Without the recording I would have described the space as being relatively quiet, however as you can hear there is pretty much constant 'noise'. What is also noticeable in the recording is the way all these sounds are effective in describing the space - the impulses arriving at the microphones are noticeably altered by the surfaces and geometry of and in the square
