CULLANAN, ALDRIN A., DIMAYUGA PRINCES MAE C., DORETEO MARK ARNIE D., NASOL, JOCYL N., REZANO, and JON DHERIC R. Development of Lesser Feedback Device for Public Address Sound System. Design Project. Bachelor of Science in Industrial Technology with specialization of Electronics Technology. Cavite State University-CCAT Campus Rosario, Cavite. May 2018. Adviser: Mr. Nemrod M. Zoleta. Technical critic: Mrs. Janice D. Marquez.
The study was conducted from March 2017 to May 2018 at Cavite State University CCAT Campus in TVEP Building to develop and evaluate the lesser feedback device for public address sound system. Specifically, the study aimed to. 1) design of device that can reduce feedback of microphone for sound system, 2) construct the leser feedback device with locally available materials, 3) evaluate the performance of lesser feedback device in terms of: a) intensity of feedback to the six speakers with and without lesser feedback device, and b) minimum time consume in calibrating the leser feedback device in different frequencies of microphone in voice of male and female; and 4) conduct cost analysis of the prototype.
The prototype was developed with two major parts namely: notch filter and power supply. The notch filter rejects a narrow frequency band and leaves the rest of the spectrum little changed. The power supply requires an input of 220V AC and has an output voltage of 9V DC, used to convert the power provided from the outlet into usable power for the many parts inside the lesser feedback device. The developed prototype size was 500 x 440 X 45 mm made by aluminum.
This study would benefit the student organization, faculty members, staff and school campus because this design project was designed to lessen or minimized the feedback into the sound system to make the audience satisfied. The findings of the study based on the result and evaluation showed that the use of lesser feedback device minimized the feedback sound problem in audible range of volume setting that used in events as compared in public address sound system with no lesser feedback device and have a minimal time consume in calibrating the lesser feedback device.
The total cost of the prototype was Php 2,196.00.
