Low-Cost and Portable Sound Reduction Box: Innovation for Acoustic Material Performance Measurement

Abstract

 Measurement of the sound reduction index with a sound intensity analyzer using the proposed sound reduction box is an alternative low-cost and portable sound insulation testing method.  The proposed sound reduction box is a miniature reverberation chamber for testing wood board samples as soundproofing material.  The proposed sound reduction box is made from medium density fiberboard.  The combination of the proposed sound reduction box with a sound intensity analyzer was able to produce similar reduction index measurement results as a standard sound insulation testing system.

Low-Cost Alpha Cabin Like Test Box Proposal for the Development of New Acoustic Sound Insulation Materials

“…Measurements were made using a sound intensity analyzer. It has been determined that the device they developed can be used as an alternative for testing acoustic materials [23].…”

“…In the literature, it has been seen that there are researches [2,3,4,5,6,9,10,11,12,13,14,15,23,24] about what acoustic materials are and what tests are applied to these acoustic materials, but the application is more limited. Due to its limitations, it was not encountered to evaluate their performance in terms of the mathematical model and to implement various variations in practice.…”
