“…As part of the Cadence Tensilica ecosystem, a comprehensive development environment, including a hardwareextensible C/C++ compiler toolchain (GCC, Clang), is included with the SmartHeaP SoC. In addition, the framework first presented in [11] has been modified through the use of hardware-extensible intrinsics to enable seamless porting of MATLAB fixed-point code to the SoC. Compared to other recently presented hearing aid processors without similar support, e.g., [12], these advances significantly reduce the development and implementation time of hearing aid algorithms.…”

With advances in algorithmic hearing aid research, the need for high-level programmable, behindthe-ear (BTE) wearable and low-power research platforms is emerging. These can be used to test new algorithms in real-world scenarios. Although various groups are developing different portable solutions, they are not in a BTE form factor. For this reason, the devices must be worn around the neck or somewhere on the body, which causes limited mobility and can lead to inaccurate research results. Therefore, this work presents a fully integrated and functional hearing aid research platform that weighs only 5 grams and can be worn behind the ear. The platform is high-level programmable, features wireless technologies such as near-field magnetic induction (NFMI) and Bluetooth Low Energy (BLE), and integrates two micro-electro-mechanical systems (MEMS) microphones and an external speaker. The audio processor of the system is based on a new custom, low-power 22nm mixed-signal system on chip (SoC). Different real-world use cases, like a dynamic compressor, are used to evaluate the platform. With a total power consumption of 47 mW, the rechargeable device achieves a run-time of six hours. When the wireless interfaces are turned off, the power consumption drops to 31 mW, and the run-time increases to nine hours.Clinical relevance-The proposed research hearing aid demonstration platform can be used portable and outside the clinical setting for algorithmic research. With its behind-the-ear form factor and rechargeable battery, studies can be conducted for several hours without restricting patient movement in realworld scenarios.
