Ear on Arm is an ongoing conceptual work in progress which has become an example of a new technological body‚ pushing Stelarc to explore transhumanism in new ways. Ear on Arm has involved the cultivation of a prosthetic ear out of cartilage and cells‚ several surgeries‚ and the insertion of a microphone and blue-tooth transmitter that would wirelessly broadcast to the Internet the sounds of Stelarc and his environment (Schwartzman 2015). It is located on his inner forearm‚ which is anatomically

5% of the world’s population – 360 million people – has disabling hearing loss (328 million adults and 32 million children). Disabling hearing loss refers to hearing loss greater than 40dB in the better hearing ear in adults and a hearing loss greater than 30dB in the better hearing ear in children. The majority of these people live in low- and middle-income countries. Approximately one-third of people over 65 years of age are affected by disabling hearing loss. The prevalence in this age group

As a result of aging‚ most of the elderly population‚ 60 years of age‚ have a condition referred to as presbycusis‚ otherwise known as age-related hearing loss (Lassaletta‚ Calvino‚ Snchez-Cuadrado‚ Prez-Mora‚ and Gaviln‚ 2015). Expected to increase‚ presbycusis is the second most common cause of disability in elders (Cuadrado et al.‚ 2013). Thus‚ cochlear implants (CIs) have become a topic to discuss to the elderly population with sensorineural hearing loss of at least 70 dB‚ when hearing aids no
