Sonic Expressions Of Changes In The Percentage Cover Of Purple Moor-Grass, By Altitude, Under Hill Sheep Grazing In Western Ireland
MetadataShow full item record
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.
