ANALISIS MATERIAL SERAT ALAM TEBU SEBAGAI BAHAN PEREDAM SUARA

Abstract 
 Material Sugarcane natural fiber material can be used as a sound absorber material. In measuring the value of absorption coefficient cane silencer using level meter application on smartphone to measure intensity (dB) and frequency generator connected speaker source (Hz). The test uses an acoustic box miniature room that will tested for its values coated with sugarcane fibers. purpose this study is find out influence fibers in reducing noise effect variations coefficient. Measurement wall produces different based source. greater value, higher value. Frequency include 500 Hz, 1000 1500 2000 2500 3000 Hz. drops at Hz but there re-increase frequencies above smallest obtained time = 0.01047 largest 0.10139. too small, so it not effective muffling sound.
