            The research team in the Virginia tech's college of engineering is attempting to find a solution to the fighter jet. The problem they proposed is that these fighter jets have huge negative impact on the ear due to the noise it produces. This project is going to attempt to solve the problem by reducing the jet's engine noise. Due to the importance of this project, NASA is partially funding this project.

            To illustrate the issue, the author compares the sound frequency by the jet and a lawnmower. He stated "tactical aircraft can reach 150 decibels on the flight line as sailors and Marines prepare fighters and other aircraft for launching. Comparatively, a lawnmower typically produces noise levels of 90 decibels." (Virginia tech, 2013) By this analogy, the audience is able to understand the importance of the quandary. This project is intended to look after the citizens, who put their hearing on the line by being on the aircraft board.  "However, the issue with the jets do not only affect citizens as an individual but they do pollute the cities with their noise." (Virginia tech, 2013).

            This result of this research will have a huge impact on the future of aircrafts and its users. Since this project is intend to prevent the engine from producing high level frequency sounds, citizens who are associated with aircrafts will not have to sacrifice their hearing in the long term. Although I discussed an article and not a blog, the author seems to be concerned with informing the public of what is to be accomplished. Also, publishing the news to the public may result in getting more funding for the project. After reading this professional engineering article, I can say that it has benefited me to realize my educational plans. Currently am studying civil engineering and I have been interested in mechanical engineering for quite a bit. Now that I read the article, am concerned whether or not should I engage in a mechanical workshop. Doing so will allow me to physically understand what these researchers are doing and whether or not I would like to pursue a career in mechanical engineering.
