Peter Arndt

Job Titles:
  • Member of the Board
  • One of Duearitys Founders
  • Visionary Founder
One of Duearitys founders, Peter Arndt, has had tinnitus for a very long time and underwent TRT treatment in 2015-2016, which involved CBT training in combination with listening to white noise 8 hours per day for a period of 12 months. Peter found that white noise offered a considerable amount of positive relief, but found that the treatment constituted a major inconvenience in his everyday life. Earpieces could not be used during working hours, since the treatment needed to be uninterrupted, and my sleep was disturbed by having to sleep with them on for protracted lengths of time. Peter Arndt is a member of the board at Duearity AB and the inventor of Tinearity G1. He has been active in a number of companies during his 30 years in the industry. The common denominators are entrepreneurship, expansion and business development strongly connected with innovative medical technology products.
