Long-term EduLink use stimulates auditory neural plasticity in children with CAPD (March 2006, PDF, 97 kB)
Studies have demonstrated the benefits of ear-level FM receiver use for children with Auditory Processing Disorders (APD). Evidence from a recent experiment¹ now shows long term benefits to central auditory processing and neural plasticity after one year of use of a special ear-level FM receiver. This highlights the role of improving the Signal-to-Noise Ratio for children with APD in possibly accelerating the neural maturation process and increasing speech recognition in noisy environments.

EduLink and its effect on understanding speech in classroom situations (January 2005, pdf, 170kB)
Children with Auditory Processing Disorders (APD) often have distinct problems in understanding their teacher. This is partly because the classmates are talking simultaneously to the teacher. This so-called informational masking further degrades understanding of the teacher. EduLink allows for substantial improvement of the SNR and thus of speech understanding even in such difficult environments.
