Cell phones with hearing aid compatibility are less likely to have noise from interference, which makes it easier to hear on the phone. Cell phones have an M rating to denote interference ...
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.
Sound intensity (sound energy or propensity to cause damage to the ears) increases dramatically with proximity according to an inverse square law: halving the distance to the sound quadruples the sound intensity. In the US, 12.5% of children aged 6–19 years have permanent hearing damage from excessive noise exposure. [15]
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.
A deaf or hard of hearing person can communicate over the phone with a hearing person via a human translator.

Most causes of vision loss can cause varying degrees of damage, from total blindness to a negligible effect. Media opacity occurs in the presence of opacities in the eye tissues or fluid, distorting and/or blocking the image prior to contact with the photoreceptor cells. Vision loss often results despite correctly functioning retinal receptors.
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.
