Comparison of battery solutions for hearing aid devices

Signia commissioned Ramboll a/s to conduct a life cycle assessment (LCA) study in accordance with ISO standards 14040 and 14044 for two comparable hearing aid devices and their respective battery solutions, i.e. a primary, non-rechargeable battery and a secondary, rechargeable battery. The overall aim was to investigate and understand the environmental impacts of two comparable hearing aid devices with different battery solutions. The two products chosen for assessments are rechargeable Signia Augmented Xperience (AX) and non-rechargeable Signia AX.

Comparison of streamed audio signal quality: what matters in the real world

Few manufacturers offer technology that incorporates both bilateral full-audio sharing of signals as well as direct streaming from a mobile device. In a comparative research project, the effectiveness of the streaming for such hearing aids was evaluated. The findings reveal a crucial difference between streaming indoors and outdoors, which is important to consider when counseling patients. Results show a substantial streaming advantage for the Signia product, and indicate that a Bluetooth based wireless approach as applied by the competitor brand does not deliver on all basic user needs.

Hearing Aid Batteries: The Past, Present, and Future

Modern digital hearing aids offer a huge variety of form factors, features, and wireless connectivity options that allow for individual hearing solutions. However, the price of functions like situation-based real-time processing, binaural algorithms, or streaming is an increased demand on battery performance. So far, the topic of efficient powering has received only scant attention, but this may change soon due to the many good reasons for using rechargeable batteries.
