Among external devices, hearing aids (a battery operated electronic device) (Cox and Alexander 1983), assistive listening devices (ALDs) (Zanin and Rance 2016) amplify the incoming sounds to make them audible for the patients suffering from superficial or middle hearing loss problems. Specific telephone equipment helps the patients to communicate over the telephone. Other than that, several automated circuits are externally or internally implanted in different parts for producing profound sound (Garin et al. 2004). RetroX, Vibrant Sound Bridge (VSB) (Vincent et al. 2004), and cochlear implant devices (Minoda et al. 2004) are also helpful for severe hearing loss problems. An online sign language translator was invented converting English news or related articles to sign language by using a Natural Language Processor (Saleem and Alagha 2016).

Assistive listening devices (ALDs) have been widely used by people with hearing loss. In contrast to hearing aids, ALDs are not regulated by the U.S. Food and Drug Administration and, therefore, are dispensed within the consumer market via drug stores, supermarkets, and mail order, without the necessity of fitting by an audiologist. ALDs can be used alone or coupled with hearing aids through near-field magnetic induction technology. By applying the wireless technologies of FM radio signals, induction loop systems, infrared light, or Bluetooth devices, ALDs can be used to transmit sounds from sources at a far distance (e.g., involving a television or a classroom lecture) to body-worn or ear-level devices; thus, the signal-to-noise ratio (SNR) is significantly improved (Hawkins & Schum, 1985). Without the transmitter, the body-worn device is also an option to hearing aids for amplifying environmental sounds by using the local microphone (Hartley, Rochtchina, Newall, Golding, & Mitchell, 2010). Other types of ALD can transmit sounds from phones or multimedia players that are either wired or wireless.
