Audicin

HRV gets talked about a lot. But most people who track it have never been told that sound can move it.

Heart rate variability is the variation in time between your heartbeats and it is one of the clearest windows we have into how well your nervous system is actually coping. Higher HRV means you are adaptable, recovering well and operating with resilience. Lower HRV means the system is under strain — even if you cannot feel it yet.

What the science shows is that sound interacts directly with the mechanisms that drive HRV. Rhythm and tempo influence breathing rate without any conscious effort, a process called physiological entrainment. Phrasing shapes the length of each breath cycle. Dynamics shift the balance between the sympathetic and parasympathetic nervous system. All passively, all while you go about your day.

In an independent study with frontline nurses, Audicin users saw a 21.9% increase in HRV across two weeks of regular use. Statistically significant. The most responsive physiological marker in the entire study.

111ms by the way is an excellent HRV score. Thanks to our friend for sharing hers

We have some exciting news ahead of Arctic15 this week.

Audicin has been selected as a Top 100 Innovation Honoree at the 100 Innovations — Shaping the Future Awards 2026 at Arctic15 Helsinki.

What makes this one feel meaningful is how companies are selected. This is not a pitch competition. Selection is based on technical validation, measurable traction and proof of ex*****on. The science and the evidence we have built around Audicin is what got us here and that is exactly how we want to earn recognition.

We will be at the Cable Factory on June 11 and 12. Come and find us at the booth.
