Millions of people take public transportation on a daily basis and most hardly worry about their health and safety and only concerned with getting from point A to point B. The London Underground may have you think differently. According to research done by University College London and the BBC in an article done by Sarah Knapton for telegraph.co.uk, they recorded noise for a week and found noises reached decibel levels of a chainsaw, some of the lines were also so loud that would require ear protection if those noises were at a work site. Dr. Joe Sollini of UCL urges the long-term effects of riding the Underground for long periods of time. “Hearing loss accumulates over time and this can increase their risk of that and potentially tinnitus.”, he states. This can potentially be a silent killer for people’s ears if no precautions are made to make the carriages safer. Suggestions have been made for this but it needs to happen now.
