The provided line graph illustrates the number of noise complaints received by Environmental Health authorities in the city of Newtown from 1980 to 1996.
Overall, the graph reveals a significant rise in complaints related to road works, factories, and traffic noise during this period. In contrast, complaints about household noise decreased. Interestingly, while domestic noise was initially the most significant source of complaints, by the end of the period, road works had become the noisiest contributor in the city.
Examining the details, the number of complaints regarding road works remained unchanged for four years between 1980 and 1984. Following this period, complaints increased considerably, reaching around 1,250 by 1996. A similar trend was observed with traffic noise, which generated a total of about 600 complaints over the same timeframe. In the case of factories, complaints rose dramatically over a two-year period, after which the numbers fluctuated, ultimately stabilizing at approximately 700.
In contrast, complaints regarding household noise gradually declined throughout the period, dropping to just 100 by 1996.
