Corporate Responsibility at Sonova

Stakeholder engagement

Sonova strives to engage in an open and transparent dialog with all its stakeholders. We actively initiate dialog through a broad range of channels as a way to promote participative and integrated decision-making.

Stakeholder groups

Sonova understands how the involvement of stakeholders supports our long-term success by enhancing transparency, broadening knowledge, and generating innovative solutions. Sonova identifies and selects relevant stakeholders for further dialog and engagement based on our existing stakeholder-facing activities and on information gathered from internal staff interviews and management workshops. We regularly interact with our current stakeholders to define their specific interests in our business activities, products and services and their influence over our decisions. Sonova has defined five key stakeholder groups:

  • Customers and consumers
  • Employees
  • Shareholders
  • Suppliers
  • Academia and opinion leaders

Further stakeholder groups important to Sonova are:

  • Financial community
  • Media
  • Regulators
  • Insurers
  • Competitors and industry

Approach to stakeholder engagement

Below you find information on Sonova’s regular engagement activities with our different stakeholder groups. In 2019/20, we additionally engaged with our key stakeholders to conduct an updated materiality assessment. More details are provided in the section “CR program” of this CR Report.

Customers and consumers

Our customers and consumers stand at the center of our business. Our business model is built on business-to-business (hearing care professionals, clinics, retailers) and business-to-consumer (end users, patients) relationships. Sonova establishes specific channels of engagement appropriate to the differing needs of each of these groups.

We ensure continuous dialog with our business-to-business customers through our sales representatives, brand tracker surveys, customer satisfaction surveys, advisory network, knowledge management and sharing, customer hotline and support, audiology conferences, online customer communities, and complaint management channels. We provide a broad range of professional training and courses that address the various specializations in the hearing care industry. We also organize e-learning seminars, road shows, face-to-face in-clinic training, and technical marketing material to help transfer our knowledge and train hearing care specialists. We conduct an annual worldwide customer survey to ensure satisfaction and loyalty of our customers. Based on this data, the Customer Satisfaction Index (CSI) is calculated and expressed on a scale between 0 and 100, the latter being the best. In 2019/20, the CSI was 79 (2018/19: 80).

We engage with end users and patients through satisfaction surveys and different communities such as the Phonak Pediatric Advisory Board,, or Advanced Bionics’ Bionic Ear Association (BEATM). The Phonak Pediatric Advisory Board was founded in 1998 to help steer Phonak’s pediatric product development and establish and recommend industry-best practices to support the needs of children with hearing loss and ensure optimal outcomes for them. Members of the Pediatric Advisory Board include parents of children with hearing loss, researchers and professors in pediatric audiology, as well as master pediatric clinicians. is an online community for people whose lives are affected by hearing loss. The website and contains stories written by people with hearing loss, their family members, or hearing care professionals. BEATM is a community of hearing health professionals and cochlear implant recipients that aims to improve the quality of life of individuals with severe-to-profound hearing loss by providing valuable information, education, and awareness on cochlear implants.


Sonova’s employees are key to its success. We foster a spirit of innovation, shared engagement, and personal responsibility. Through our vision, we want to ensure that our employees experience their work as genuinely meaningful. Sonova actively engages with its employees through its annual employee engagement survey called “HearMe” and through its annual appraisal process. The employee appraisal meeting is an essential process to assess satisfaction, provide feedback, and define expectations for behavior and performance. It supports each employee’s personal and professional development and helps to build trusting relationships by providing a format for open dialog. We estimate that around 30% of Sonova’s global workforce is represented by an independent trade union or covered by collective bargaining agreements.


Sonova has 17,449 registered shareholders, who together own 66.09% of the total shares. Shareholders’ interests are represented by the Board of Directors, which sets and oversees the general direction of the company. We publish an Annual Report for shareholders and other stakeholders, and hold an Annual General Shareholders’ Meeting, which provides a forum for discussion and debate as well as an opportunity to vote on compensation for management and the Board of Directors. Each share entered in the share register with a voting right entitles the holder to one vote at the Annual General Shareholders’ Meeting.


Suppliers are an integral part of Sonova’s value chain. Our relationship with our suppliers is governed by Sonova’s Group Supplier Principles (SGSP), which are based on a range of international standards, customer requirements, and industry characteristics. We assess all new suppliers on their management systems. We regularly audit and visit suppliers and inspect their management capabilities through employee interviews and on-site inspections.

Academia and opinion leaders

Sonova’s know-how and history of innovation is reflected in its strong partnerships with leading academic institutions and opinion leaders around the world. We collaborate intensively with universities such as the University of Zurich, the University of Hannover (Germany), the University of Oldenburg (Germany), Vanderbilt University in Nashville (US), the University of Melbourne (Australia), the University of Queensland (Australia), the University of Western Ontario in Waterloo (Canada), the Swiss Federal Institutes of Technology (ETH) in Zurich and Lausanne, and the University of Manchester (UK). We foster a close collaboration with these partners by offering support toward diploma theses for Master’s or PhD students. We do not just support studies financially, but, when appropriate, participate in the actual work by closely collaborating on research projects.

Financial community

As a publicly listed company, Sonova pursues an open and active information policy. A governing principle of this policy is to treat all stakeholders alike and to inform them at the same time. We actively interact with the financial community at roadshows, conferences as well at investor meetings and conference calls. Sonova holds an Investor and Analyst Day every year at its headquarters in Stäfa; last year’s event again attracted significant interest from the international investor community, with around 100 participants attending. We also hold regular exchanges with environmental, social and governance (ESG) investors and rating agencies.


Sonova drives and maintains a strong in-depth relationship with a variety of media representatives as part of its commitment to ensure transparency, dialog, and accountability for all of its activities. The media relations team works globally with top-tier media, public interest media, trade and special interest media, financial and economic media, and the major wire services to ensure a fair disclosure of information to all stakeholders, creating – amongst other topics – awareness for hearing loss and its implications and of informing on key aspects of Sonova’s business performance. We maintain a close and cooperative dialogue with the media by creating news. We proactively distribute press releases and publish it on our corporate website, organize press conferences, media trips, events or respond to requests when journalists are developing stories.


Sonova’s products are regulated medical devices, which means that the company must meet statutory patient safety standards and functional performance claims with clinical evidence. We recognize our responsibility to share our specialist knowledge in external working groups to help define, on behalf of our customers, the regulatory principles that will ensure the highest quality standards for hearing instruments and cochlear implants.


Governments and social institutions such as the Veterans Administration in the United States and the National Health Service in the United Kingdom, as well as public and private insurance providers, all contribute to improve access to hearing care. Sonova regularly participates in tender processes and offers its products and services to help insurers receive the best hearing value for their money.

Competitors and industry

Sonova’s competitors aim to gain market share. This competition generates improved service for customers and drives Sonova to push yet further the limits of technology. We are committed to fair competition, defined in detail in Sonova’s Global Competition Law Policy. Sonova interacts with representatives from competitors e.g. through membership in industry associations such as the European Hearing Instrument Manufacturers Association (EHIMA), which represents the major European hearing instrument manufacturers.

Caring for stakeholders, delivering on our commitments, and taking responsibility: these principles guide our daily actions in “normal” times, and yet more so during the unprecedented COVID-19 pandemic that has impacted the last weeks of the past financial year. Sonova’s first and foremost priority in the response to COVID-19 has been to protect the health and safety of our employees and their families, as well as our customers, consumers and partners. We have taken accountability as a global company, helping to limit further spread of this virus to the best of our abilities, whilst ensuring continued access to hearing care for people in need. We have supported all our stakeholders in navigating through these challenging times, whilst also taking proactive steps to safeguard Sonova’s financial health, maintain employment, and secure sustainable operations. In this crisis and thereafter.
