Shortcomings:

1. As the devices used were considerably differing in quality of sound receptor hardware, even setting up a control system was just an approximation of the actual noise levels.
   
2. More data points could have been helpful, multiple times during the weekday/weekend, different times of the semester/year. It is still unclear as to what the correct size of the data set would be.
   
3. Unfamiliarity with data collection of this type greatly contributed to the initial confusion in setting up the right process to collect all the information that was needed as per the narrative.
