Notes

Earcons (4)
(Brewster,Wright and Edwards 2000)

Intensity

Main cause of annoyance

Keep all earcons within a narrow volume range (reduces loss and annoyance)

Do not use for differentiation: poor user judgement

 

Spatial location

Can be 2D or 3D

Placement of sound improves identification

Spatial location also improves differentiation of simultaneous presentation
