The NIDCD has funded a number of projects to develop portable signal processing tools that enable real-time processing of the acoustic environment. The overarching goal is to provide a large group of researchers with the means to efficiently develop and evaluate novel signal processing schemes, individualized fitting procedures, and technical solutions and services for hearing apparatus such as hearing aids and assistive listening devices. We report here on a development done in the SBIR Phase II Project R44DC016247. This project builds on the software being concurrently developed in R01DC015429 to provide a complete portable and wearable software-hardware master hearing aid device needed for development of new solutions for assisted hearing. We will present and demonstrate the portable platform, currently in the Beta launch, that consists of a Cortex A8 based processing unit and a codec set able to support hearing aid architecture of up to 6 microphones and 4 speakers. It is currently accompanied by a binaural 2-microphone BTE hearing aid set, but will also support different headset form-factors of our partners. Additionally it features stereo line in and line out connections. The device can be remotely controlled with a smart phone.The NIDCD has funded a number of projects to develop portable signal processing tools that enable real-time processing of the acoustic environment.
