Sound marks are the sonic equivalent of landmarks. They are key sound objects within a soundscape which help us to orientate ourselves.
Sometimes Sound Marks are also Keynote sounds, but not always.
Think of giving directions. We use landmarks to describe where we are or how to get somehwere.
“Go down to the shops, turn left and you will find ‘X’”
In this example ‘the shops’ are the landmark. They act as a fixed point of reference around which the navigation can happen.
Soundmarks are exactly the same for sounds. They are key sonic points of reference that help us to orientate ourselves within the soundscape. for example:
“When you hear the seagulls you will know that you have reached the seaside”
