In addition, auditory exclusion can have a protective purpose. In situations like combat, where the noise created by gunfire or explosions is loud enough to cause significant damage, an individual's hearing can be suppressed or muted to the point where they are unaware of the severity of the noise until afterwards.
Primary causes of hearing loss due to an impaired sensory system include long-term exposure to environmental noise, which can damage the mechanoreceptors responsible for receiving sound vibrations, as well as multiple diseases, such as CMV or meningitis, which damage the cochlea and auditory nerve, respectively.

Diagnosis of the cause of a hearing loss is carried out by a specialist physician (audiovestibular physician) or otorhinolaryngologist. Hearing loss is generally measured by playing generated or recorded sounds, and determining whether the person can hear them. Hearing sensitivity varies according to the frequency of sounds.
Mobile phones continue to become more multifunctional and sophisticated, which exacerbates the problem. [48] In 2014 the BBC reported concerns from opticians regarding blue-violet light emitted by cell phone screens, that it may be potentially hazardous to the eye and long term it may possibly increase the risk of macular degeneration.

For those with hearing difficulties the telephone ring and conversation sound level can be amplified or pitch adjusted; ambient noise can also be filtered. The amplifier can be a simple addition or through an inductive coupler to interact with suitable hearing aids. The ring can also be supplemented with extension bells or a visual call indicator.
VCO telephone calls must be made through a relay service. This connection allows the person with the hearing loss to speak to the other party and read their incoming message on the telephone's display screen. There is also a portable VCO device, which can be attached to cell phones, pay phones, or cordless phones.
