"For years our team have been re-thinking the design of audio products to reduce the detrimental distortion that traditional approaches can’t address. I experienced a Eureka moment and uncovered a way to target distortion at source; in the human ear itself."
A small wearable device
Calmer sits barely visible in the ear and uses revolutionary (non-electric) technology to reduce mid and high frequency distortion without having a detrimental effect on our hearing.
The result is a natural way to minimise today’s constant barrage of environmental noise stressors which have a negative impact on our mental and physical well-being.
Calmer reduces stress by removing distortion that would usually trigger the human ‘fight or flight’ response.
While this response was a vital part of our evolution to alert us to the slightest sound or threat, in today’s modern world where we no longer need to be alert to the snap of a twig, this added resonance is loading us with unnecessary stress.
Here’s a graph to show you how Calmer is affecting sound energy in our ears. As you can see, the blue area shows a reduction in unwanted energy (distortion) between the frequencies of roughly 2 kHz - 8 kHz when Calmer is worn. As a result, this produces a much more even response and therefore an improved and more pleasant sound.
The black area (without Calmer) shows the natural peaks of energy that result in harsh noises that trigger a stress response.
As these trigger frequencies are reduced, so too are your stress levels.
World Health Organisation
The World Health Organisation published evidence (2018) that unpleasant, loud or disruptive noise contributes to raised stress levels, a multitude of health issues and even increased risk of premature death.
Calmer’s technology is informed by research from Newcastle University and the Welcome Trust Centre for Neuro-imaging at UCL, which reported in the Journal of Neuroscience that many of the most unpleasant sounds, such as the scraping of a knife against a bottle, fall in the mid frequency range of about 2 kHz to 5 kHz.
Our ears have evolved to alert us to stress by adding over 20 dB of mid-range resonance, which destroys our ability to hear high definition sound or relax in our modern noisy world. This is known as HRTF (Head Related Transfer Function).
