High school students discover sound absorption material using natural fibers

One classroom being divided into two during lectures has inspired three high school students to experiment and find ways to minimize the noise coming from both classes.

Their school’s situation has led them to discover sound absorption materials using natural fibers such as abaca, bamboo, and water hyacinth.

Students Evan Relle Tongol, Shaira Gozun, and Neil David Cayanan of Angeles City Science High School in Pampanga came up with the idea to make use of natural fibers to sound proof classrooms that were usually divided to accommodate more classes.

“Yung mga classroom po dito madalas dini-divide po sa dalawa so, nagkakarinigan po ng noise ng bawat classroom,” Tongol said in a video produced to feature their study.

Their brilliant discovery entitled “Hibla” also led them to be named as the Best Team Research in Physical Science in the Department of Education’s 2019 National Science and Technology Fair, which became their ticket to an international research competition.

The trio was one of the six entries of the Philippines to the 2019 Intel International Science and Engineering Fair held last month. 

According to the group, they had to travel to five different institutions in Manila to process the materials and test their product.

They also reached out to an expert in the United States for further testing of their product.

The young researchers hope that their study would be a stepping stone for a new industry in the country.

“We have this stigma na hindi po natin kayang gumawa ng mga ganitong klaseng materyales. Hindi po alam (ng marami) na meron po tayong kakayahan tapos yung mga materyales po natin local at masasabi natin na tatak Pinoy talaga,” Cayanan said.

They also hope that students their age and even younger would not hesitate to pursue studies that will greatly help the community.

“Ang daming ideya yung mga bata pero mas maa-apply po nila yung mga ideya na yun kung mabibigyan ng sapat na pondo yung mga researches na ‘to,” Gozun said.

Filipino youth, they said, should continue to question themselves on how to help the country.
