For the final part of the sound project, we invited people from the Teen Center and the community to decorate foam acoustic panels with fabric to reduce noise in the homework room in a personalized, beautiful way! First we did some testing to get "before" conditions for the homework room. We created the "mini rooms" to model with and without sound panels and compared using speakers, various sound meters on phones, and even our heads. Next we used a sound meter to test sound levels in the homework room in a variety of conditions including silence, small talk, music playing, someone singing or yelling, and a frequency sweep. We also considered whether the sound was coming from inside or outside of the homework room. Creating the acoustic panels...so far we've made over 30!

Everyone did a great job presenting today! Our data analysis team presented on the sound project and their participation as community scientists, but it's important to recognize this is only one part of the larger "I'm a Student Too" campaign that these youths have been working on for the past two years. The extent of their data collection and analysis is impressive, as is their commitment to making Isla Vista a "better, safer and healthier place where youth and families can grow up." Our data analysis team began by presenting how sound was a big issue in the initial survey, and their response of collecting data on sound levels to answer specific questions seen below. They also presented on the process of data collection and analysis for the sound project that took place over the past few months. Finally, they showed some of their results. See previous blog post for graphs, and check out the map below of representative sounds! We've been busy this week! Our data analysis team created graphs and visuals to represent the data. One group worked on creating sound graphs and figuring out which types of sounds created the loudest and quietest decibel readings. We created graphs using the max and average db readings according to time of day to see which days and which time periods were the loudest. Another group created a map of Isla Vista and polled people about which sounds to include on the map. Then they helped create an interactive map with representative sounds at places such as Children's Park, the Habit, the Loop, the Teen Center. A photo of our map in progress is below, the video will be next!
We downloaded and formatted data today, looking over the dates from March to May, the location, time of day, max, min and average sounds. We have over 125 data points from our sound blasts and people collecting it on their own! A big thanks to Saul for help with organizing the data into a readable excel format. Our data analysis team also thought about their original questions and came up with these to look through for the next step:
•What day of the week was it the loudest? •What day of the week was it the quietest? •What time of day was it the loudest? •Where was it loudest? •What caused these different types of sounds? •What source caused the loudest sound? |
