What emerging technology is described as allowing the deaf to feel sound?

Haptic feedback technology is designed to provide tactile sensations in response to sounds, vibrations, or other stimuli. This capability is particularly significant for individuals who are deaf or hard of hearing, as it enables them to perceive sound through touch. By using various devices that emit vibrations or pulses, haptic feedback technology allows these individuals to "feel" music, speech, or environmental sounds, thereby creating a richer experience that goes beyond what traditional sound systems can offer.

In contrast, biofeedback systems focus on measuring physiological responses to improve health or manage stress, rather than conveying sound as tactile feedback. Language learning devices typically assist with language acquisition through auditory and visual means but do not cater specifically to the sense of touch in relation to sound. Advanced hearing aids enhance auditory perception but do not provide the tactile experience that haptic technology does. Therefore, haptic feedback technology stands out as the solution that directly addresses the unique needs of those who are deaf, enabling them to engage with sound in an innovative way.
