Social Ear Social Impact Logic Model “Designing sustainable hearing health” Leading indicators = Impact CURRENT IMPACT Inputs Activities Outputs Outcomes 36 deaf employees 5 Million of funding 4 Corporate partnerships Detection Research & Advocacy Education Equipment Therapy Capacity Building 2.5 million detections Equipment purchased by 100K hearing impaired people Of these, first-time access for 50,00 20,000 beneficiaries involved in education/therapy programs .Solar Ear hearing health centers in 75 countries Extensive health distribution system and infsstructure Decreased burden of hearing loss, measured by: Increased access to education (e.g. 6K hearing impaired children in Brazil now attend school) Decrease in disease rate (e.g. HIV rate in Botswana lowered from 38% to 10%)) Employment/increased income for disabled as 55 hired by other companies Policy change (e.g. Change in Chinese workforce policy – for the first time deaf citizens can work in the electronics industry Savings of ~300K USD/individual related to loss in work productivity, special education services and medical costs Bene-ficiaries Health Improve-ment Efficiency Gain Structural Gain Hearing impaired are able to achieve their full potential and contribute to society

CURRENT Social Impact: Solar Ear Indicator Measurement CURRENT Social Impact: Solar Ear Significant health issue Qualitative & Quanitative Measured by size of problem and need of solution: market opportunity 624 million hearing impaired 66% in emerging markets; but only 10% of hearing aids sold in emerging markets 70% of individuals in USA cannot afford hearing aid Beneficiaries Quanitative Number of beneficiaries (particularly those that did not before have access) 100,000 hearing impaired purchased Solar Ear products over past 7 years Of these, a hearing aid was out of reach for 50,000 20,000 have benefited through empowerment programs and speech pathology Health/wellbeing improvements Positive changes in health situation for individuals and communities with focus on health outcomes (e.g. % decrease in disease transmission) and not necessarily results (e.g. number of test administered) 6K chidren in Brazil learned to speak/communicate through access to speech therapy, and thus attend school Lowered HIV rate in Botswana from 38% to 10% In China, change in workforce policy – for the first time deaf citizens can work in the electronics industry Employment and increased income for workers and micro-entrepreneurs Efficiency gains Cost savings for individuals and society by assigning monetary values to outcomes. (Resource: Social Evaluator’s SROI guide) Individual: Solar Ear hearing aids are 90% cheaper than mainstream hearing aids Society & government: Early diagnosis and intervention reduces future costs; severe to profound hearing loss estimated to cost society 300K USD over an individual’s lifetime (67% due to losses in work productivity; 21% related to special education services; 11% related to medical costs) Environment: 200,000,000 batteries thrown out annually (zinc battery lasts 1 week and a Solar Ear lasts 2-3 years) Scalability (and sustainability) Qualitative & Quantitative Relevance of model in other countries Sold in 39 countries « Train the trainer » model facilitates internal knowledge transfer Structural change Qualitative Measured by MMH barriers and principles Designing sustainable hearing health by overcoming barriers of « no access » and « misaligned incentives » by « designing for efficiency »

FUTURE Social Impact – Solar Ear Indicator Measurement FUTURE Social Impact – Solar Ear Significant health issue Qualitative & Quanitative Measured by size of problem and need of solution: market opportunity Hearing impaired population is growing – estimated at 900 million by 2025 , but with Solar Ear program will be lowered by 50% Beneficiaries Quanitative Number of beneficiaries (especially those that did not before have access) Within 5 years, lower hearing impairment for 40 million people and improve the ability to communicate for 60 million people Create jobs for 10K micro-entrepreneurs, 10% with a disability Test over 24 million individuals per year within 5 years and 50 million per year by 2025 Health/wellbeing improvements Positive changes in health situation for individuals and communities with focus on affordability, accessibility, awareness and acceptance.) Lower burden of hearing lost for 100 million people by 2020 Education programs will not only cover hearing prevention but also maternal health and diabetes education – thus impact goes beyond hearing improvements Solar Ear hearing health model can be replicated for other health and communication disorder problems Efficiency gains Cost savings for individuals and society by assigning monetary values to outcomes. (Resource: Social Evaluator’s SROI guide) More governents will screen babies for hearing loss at birth since it is more cost effective to treat hearing loss in a baby versus finance a child in a school for the deaf later on in life Solar Ear distribution infastructure can be used to deleiver other health medical products and prevention programs or services Scalability (and sustainability) Qualitative & Quantitative Measured by relevance of model in other countries Replicable model of DREET centers and micro-entrepreneurs with operations in 15 additional countries selling to over 75 countries (within 5 years of receiving investment) Training program translated into 18 languages Technological innovations to create next generation of low-cost hearing aids (e.g. i-pod design) Structural change Qualitative Measured by MMH barriers and principles Designing sustainable hearing health by overcoming barriers of « no access » and « misaligned incentives » by « designing for efficiency »
