In my paper I will be talking about episode # 6 of ways of hearing, in which Krukowski goes into explain about how digital technology has changed our world. While it is true that noise play a big role in sound. Nowadays people can’t hear well because of the noise that surround us. “We are at risk of losing our hearing” Krukowski states, because of the personal audio devices calling it ‘unhealth listening practices’, what makes you want everything lauder to reduce the noise from outside. Krukowski also explains that signal and noise are all together at analog world. In a digital audio world, everything can’t be louder than everything else ,there is not noise to restrict signal. In my paper I will explain how the switch of analog audio to digital audio has changed our perceptions of time, space and intimacy.
