earHD uses a 60 degree reception from left to right to focus sound coming into our ears. Simply put: where we look is where we want to hear in high definition, sound coming from elsewhere is blurred out and reduced.
In order to receive higher levels of detail from the front, earHD acts like a satellite dish and diffraction shield combined.
It uses a precise acoustic lens that focuses sound uniformly into one central location. This focused sound is then accurately reflected straight into our ears, revealing higher definition sound from where you are facing. The diffraction shield aspect blocks unwanted higher frequencies from outside the desired 60 degree reception window that would have otherwise entered our ears at a much higher level which normally damages harmonic reception.
The ISVR (Institute of Sound and Vibration Research) at the University of Southampton has conducted completely independent tests on earHD to verify our claims. You can download the full report below.
