The main beneficiaries are children from birth to school age. The equipment to be acquired will allow the detection and diagnosis of hearing pathologies in healthy or high-risk children up to school age, which will improve access to early diagnosis and timely treatment, thus reducing the co-morbidities that hearing loss can cause. All children born at Penna Hospital (approximately 2,500 births per year) and those derived from other public and private health institutions in Bahia Blanca and the region (300 kilometers around) will be attended to. Penna Hospital is the only public maternity hospital that performs hearing studies. The Hospital's area of influence covers 80,104 km² with a population of almost 700,000 according to official estimates for 2019. Attention will allow early detection of hearing loss and timely diagnosis, thus reducing co-morbidities in the child's development and decreasing the costs of medical treatment throughout life.
