This technology is co-owned with Creighton University. Noise-induced hearing loss (NIHL) is the most common sensorineural hearing impairment. The World Health Organization recently reported that more than a billion teens and young adults worldwide are at risk of NIHL caused by loud music, and this number is rising. Acute or chronic acoustic overexposure has put more than 40 million U.S. workers at risk of permanent hearing loss. NIHL is also prevalent in military settings, costing more than $2 billion per year in veterans (VA) compensation. Noise trauma results in two types of hearing loss, depending on intensity and duration: permanent threshold shift or temporary threshold shift (PTS or TTS). Although people can recover from TTS within 24-48 hours, PTS is irreversible because it involves the loss of auditory cells in the cochlea.
