Introduction The current paper examines the impact of cochlear implants (CI) on Deaf communities and cultures. First, how this technology was received by these groups is considered; then, the cultural effects of the implants are discussed. Even though the implant was received negatively by Deaf people, it is argued that their reasons are practically weak; this is important because using the implants might considerably increase the quality of life of persons with “hearing loss”. Besides, it is shown how the use of the implant might affect individuals with different cultural (for hearing status) identities, which is important because it might have a considerable influence on the manner of life of people within some of these groups. How Was the Cochlear Implant Received by the Deaf Community? According to Mauldin (2014) and Sparrow (2005), the deaf community mostly had negative perceptions about CI. The greatest protest coming from that community was related to the utilization of CI for young children (Mauldin 2014). In certain cases, some representatives of the deaf culture stated that the implementation of CI was akin to “genocide” (Sparrow 2005, p. 135). Representatives of the groups with adverse attitude to CI provide several arguments against these devices. It is suggested that deafness should not be perceived as disability, but as a characteristic of a person; that deaf persons better develop other senses (e.g., better vision), which can replace the absent or low hearing; and that the disadvantages related to deafness originate from the dominating culture (Sparrow 2005). The notion of a “normal person” is discussed as well. It is also argued that deaf people have their own identity as deaf and that they have their own culture. Thus, installing CI on deaf or hard of hearing individuals (DOHHI) roots that culture out (Sparrow 2005). Also, using these devices on small children deprives them of the chance to choose their own identity and become members of the deaf culture (Sparrow 2005). However, the proponents of CI stress that DOHHI suffers from numerous disadvantages in the current world (Mauldin 2014). In particular, due to their absent or impaired ability to speak, they are unable to communicate with the majority of people as easily as hearing people do; it is difficult for them to pursue an education; they have considerably more difficulty finding a job (not only due to the deafness but also because of generally poorer education), and so on. While assessing the arguments of the sides, it might be stated that the reasoning of the opponents of CI makes sense theoretically, but appear to be less effective in practice, especially in comparison to that of the proponents of the implants. It is possible to define the word “deafness” using not the word “disability” but the words “feature” or “characteristic”, and thus to state that deafness does not require treatment; however, in practice, an individual with a “hearing loss” in the current world will often require additional assistance to make their quality of life equal to or better than that of a person with “normal” hearing (Kumar et al. 2014)–e.g., with a hearing threshold of up to 15 dB (Haynes, Moran & Pindzola 2012, p. 276), to take one definition. Of course, if there exist
