Signia Rechargeable hearing aids reduce environmental impact by 65%, according to a new study|


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. A user who uses two hearing aids can save over 100 batteries each year.

Signia is committed to improving our environmental footprint and the battery is the most important lever we have identified. We want our customers aware of how easy it can be to positively impact the environmental impact by 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 strong evidence of how rechargeable hearing aids can make the environment a better place, and that is very important. 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. You don’t have to compromise on quality or comfort in order to reduce your environmental footprint. Signia empowers wearers to make a sustainable decision for the environment and to take action so that they can live the Signia brand promise: to enhance human performance,” states Samy Lauriette (Global Head of Brand).

Signia offers a wide range of rechargeable products that cover all forms. Signia Active X, Insio Charge&Go X for In-The Ear solutions, Pure Charge&GoT AX and Styletto X to receiver-in-canal devices, and ending with 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 conforms to ISO 14040/44 standards. The assessment report is kept in our files.

* 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 impact includes 18 impacts categories, including. Climate change, fine particulate matter, fossil depletion and freshwater eutrophication are all included in the total environmental impact. All statements are based the underlying functional units of the assessment. “Use two hearing aids for 12 hours per day, with an average use profile for a period of 5.55 years in the EU28.”
