Safehear

THE SUPPORTED START-UP

Safehear

Louis is an ergonomic and compact box connected to a hearing protector that allows people working in a noisy environment to communicate while protecting themselves from noise pollution. Louis was developed in collaboration with industrialists to better meet their needs. In the midst of the surrounding noise, it is able to recognize the users’ voices so that they can communicate in real time and in a “natural” way.

The project and its context

The Safehear adventure began with the response to a constraint: to enable employees working in noisy environments (industrial sites) to communicate without latency and without risk of hearing loss. Héléna Jérome and Antoine Kuhnast, co-founders of the French start-up, hired partners from the major players in the in-ear market and research institutes to develop their solution. The outcome was a Made in France product named Louis; it is now promoted by a dynamic technical and commercial team.

Founder and Director of New Technologies

We are very happy to work with EFI Automotive Service for our first steps in the world of industrial/series production. In addition to benefiting from quality work, it is also a guarantee of strong credibility for our partners.

Project milestones

October 2021

INITIAL CONTACT PHASE

The start-up contacted our teams through the Group’s industrial accelerator – Axandus.

May 2022 – November 2022

PROTOTYPING

The teams start the design phase of the prototypes for the start-up.

December 2022

PROPOSAL OF SUPPORT FOR THE CONTINUATION OF THE PROJECT

Our teams have already proposed to the start-up to go further, by suggesting improvements for the second version of Louis.

March 2023

END OF COLLABORATION WITH OUR COMPANY

With no further need for our services (prototyping), the Safehear teams decided to end their industrial collaboration with our company.

Our added value

Within the framework of this project, one of EFI Automotive Service’s first in the support of innovative companies, we were able to offer Safehear our expertise in the following areas:

  1. Design and production of prototypes (80 planned by 2023)
  2. Provision of a 30 m² pressurised room allowing the teams to work in a controlled environment
