Signia Rechargeable hearing aids reduce environmental impact by 65%


PISCATAWAY, N.J., Dec. 20, 2021Signia, the hearing aid innovator, today published a new study about the environmental benefits of rechargeable hearing devices.

Signia is the only company in the hearing aid market to have completed a scientific life cycle assessment (LCA), which compares the lifetime environmental impact of rechargeable and nonrechargeable hearing aids. The assessment indicates: compared to non-rechargeable Signia AX, the rechargeable Signia Augmented Xperience (AX) reduces the total environmental impact* by 65%, which is an average of reduced impacts of 18 environment categories, including climate change (57%), fossil depletion (52%), human toxicity non-cancer (76%), land use (87%), marine ecotoxicity (78%), etc. Two hearing aids per user can save more than 100 batteries annually.

Signia is committed in improving our environmental footprint. The battery is the largest lever we have identified. We want our customers aware of how easy it can be to positively influence the environment, by simply switching to rechargeable hear aids,” says Frank NaumannSignia’s Senior Director of Global Innovation, who was responsible for the LCA study.

Signia is committed to sustainability. Signia’s LCA results are a clear indicator of this and are part of a series that Signia has either in motion or is ready to launch in 2022.

The study shows that for non-rechargeable hearing aids, the battery solution (i.e., production, distribution, and disposal of batteries)contributes to more than 80% of the total environmental impact.* On average, for a Signia rechargeable hearing aid, the battery solution (i.e., production, distribution, and disposal of batteries) contributes to only about 5% of the total environmental impact.* Electricity demand for charging contributes on average another9% of the total environmental impact,* but the difference is still significant.

Signia offers a wide range of rechargeable hearing aids that can be used for up to 61 hours on one charge.

We now have solid evidence that rechargeable hearing aids are better for the environment. They are also extremely easy to use and very practical. They can be stored in your charger at night so you’re ready to go every day. It doesn’t mean you have to sacrifice quality and comfort in order reduce your environmental footprint. Signia empowers its wearers to make a conscious choice for the environment, and take action to live the Signia brand-promise to enhance human performance,” says Samy Leuriette, Signia’s Global Head of Brand.

Signia offers a wide range of rechargeable products that cover all forms. Signia Active X and Insio Charge&Go X are In-The-Ear solutions. Pure Charge&GoT AX and Styletto X are receiver-in-canal devices. Then, there are the Behind-the Ear solutions, Motion Charge&Go X or Motion Charge&GoP X.

Ramboll conducted the study and TV NORD, an accredited certification body, audited it. The study was conducted in accordance with ISO 14040/44 standards. The assessment report is kept on file.

* Total environmental impact: The total environmental impact throughout the life cycle of the hearing aids, including raw materials, production, transportation, usages, and disposal phases. The total environmental effect includes 18 impact categories. Climate change, fine particle matter formation, freshwater depletion freshwater eutrophication freshwater toxicity, freshwater eutrophication and freshwater toxicity are just a few of the 18 impact categories. All statements are based upon the underlying functional unit of assessment. “Use two hearing aids for 12 hours per day, with an average use profile for 5.5 years in EU28.”
