According to Dr Murray Schafer, there are three different types of soundscape which is sound signal, keynote sounds and soundmark.
Sound signal is the sounds that have message and function: in the listening practice, the sound signal that I found are the gate in the entrance of LCC and the card registration machine in the entrance of every classroom
Keynote is the sound that being heard constantly or frequently which stand out from the background sound: the keynote that I found in LCC are the fire alarm panel in the cafe and water pipe in the bottom floor of media block.
The last sound is soundmark which refer to the unique and iconic sounds within the curtain community: the sound that I found are the gate in the entrain (also a signal) and other sound that come up in the discussion in class is the transition from outside to inside the quite zone in the library.
