"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."
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).
