That damage can be attributed, at least in part, to lifestyle choices. We cram into subway cars and airplanes and surround ourselves with raucous noises inside concert venues and sports arenas. According to the National Institutes of Health, exposure to any sound—either quick or prolonged—over 85 decibels (dB) can lead to noise-induced hearing loss.
Jesper Ray has developed the engineering around the Ray Earplugs which use Dynamic Attenuation, an intricate mechanical process that filters sound. While traditional earplugs distort and muffle, Jesper Ray developed a proprietary combination of high and low pass filters that allow the DUBS to reduce volume while preserving the proper balance and clarity of the sound you hear.
