Abstract
Preliminary investigations into the sonification of data
representing the percentage cover of Purple Moor-grass as a
function of altitude over a 14-year period from 1995-2008 are
presented. The source of the vegetation data was the Teagasc
Hill Sheep Farm in Leenaun, Co. Mayo, which was grazed at
0.8 ewes/ha/yr. Purple Moor-grass was the dominant vegetation
species. It underwent several contrasting changes by altitude
over the 14-year period. Sonification was applied to these
changes in order to enhance the comprehension and
interpretation of their graphical presentation for attendees at
lectures/conferences who suffer from impaired visual but not
acoustic acuity. Five auditory graphs were created, each
representing unique changes in percentage cover of the
vegetation, especially Purple Moor-grass by altitude. Each
auditory graph was designed to convey an accurate
representation of the data, highlighting important features.
Visual graphs corresponding to the auditory graphs are also
presented.
