1 CEFPI Workshop Darwin 2009Improving Hearing Health in Classrooms to boost Student Learning and Teacher Wellness
2 Today we will discuss how: Noise pollution limits each learner’s ability to comprehendThe peril of distance impedes the peak performance of young brainsTeacher wellness can be boostedNot all children are the same and they do not have all word filesHearing Health of classrooms can be instantly improved to benefit the educational ambitions of students, teachers, administrators and architects
3 Learning today involves …. Aging and changing infrastructureMore ESL studentsLarger classroomsMore vulnerable learnersLiteracy and numeracy assessment/fundingTeacher wellnessAll children do not have all words files installed yet – two thirds heard is two thirds learned
4 Barriers to Hearing Clearly Internal School NoiseAmbient Noise is measured in an empty classroomExternal NoiseClassroom NoiseNoise pollution reduces the ability of young brains to capture and process the sounds of teaching
5 Hyper Physics (@ C.R. Nave, 2005) Inverse Square LawThe Inverse Square Law: Voice level is reduced by 50% each time the distance from the sound source doubles.Typical Ambient Noise: 45 dBHyper Physics C.R. Nave, 2005)
6 Directionality and distance The further a learner is away from a sound source, the less they get.Visual technology can compound the problem
7 Other Issues Now Linked to Classroom Hearing Health Teacher wellness:FatigueStressIllnessJob Satisfaction19962007Teachers with voice related problems are on the rise18% miss work each year due to voice issues43% reduce instructional activityNational estimated cost - $2.5B2004Source: Parker & McDade 2004

10 How It Works: Capture all the sounds of teaching in ‘huggable’ way
11 Delivery Consider technology which embraces Wide dynamic range to ensure consonant sounds aredelivered to maximize speech intelligibilityVoice capture for all presentersBest distribution to compliment aesthetics and purposes

15 What are teachers and school administrators saying about Classroom Sound Enhancement? “It makes words sound clearer. For example I don’t have to ask “what was the word” again and again”. “It’s just great and clearer. I just love it” Student, Sunshine Coast Grammar“Delivery of clearer and more easily understood instructions has enabled the students at the back of the room to become part of the class and they are less likely to be disengaged and distracted. The ‘quieter’ students now feel that they can have the opportunity to be involved. The opportunity to quickly and efficiently use the huge range of resources on the internet (including sound resources) has positively impacted my classroom” Cronulla High“The gentle amplification of the teacher's voice enables boys to more clearly hear what is being taught or asked, meaning for the first time, some boys are able to be focussed right from the start of a lesson, rather than in the follow up phase. It is even more impressive when boys themselves realise the impact this has on their ability to learn” Scotch College Junior School, Melbourne.“We have just had a revolutionary new classroom sound system put in each classroom here as part of our redevelopment. The feedback from the boys has been incredibly positive and we have only had it in less than a week.” Newington Preparatory School

17 Classroom Sound Enhancement Validated Massie, R. (2003). The impact of sound field amplification in mainstream classrooms.This study supports the use of sound-field amplification to advance the acquisition of literacy and numeracy skills for children in mainstream classrooms, and not only for those children with identified hearing loss or with ESL backgrounds. Sound-field amplification may be viewed as a cost-effective part of the solution to improving classroom listening environments for all children.
18 12 Positive Changes in Student Functioning 1. Increased students’ attention spans2. Decrease in need for behavior management3. Decreased number of requests for repetition4. 72 % decrease in teacher redirection5. Decreased vocal strain and fatigue for teachersIndependent Trost Study December 2002; Language, Speech and Hearing Services in Schools October 2000; Language Speech and Hearing in Services in Schools July 1990.

21 Summary Classrooms are polluted with noise Not all learners are close to sound sourcesNot all children are the sameThere are many sounds of teaching we need to embrace and plan forHearing is fundamental to learningOptimizing hearing health is simple, huggable and cost effectiveThe results are proven and easy to understand
