Noise, reduction, tanned leather, materialAbstract
One thing that needs to be considered in providing a comfortable atmosphere is noise. High noise levels can reduce room productivity, therefore effective acoustic materials are needed. Material that can be used as a noise reduction material is leather. Leather is usually used as decoration for interior elements, but never been used as a material that has functional value as a noise reduction, so the research is needed to see whether there is potential for tanned leather as an alternative material for noise reduction. This research aims to obtain data on the potential of tanned leather in dealing with background noise. This research uses an experimental method of chrome-tanned leather (Pull-up) and vegetable-tanned leather, which are measured using a sound level meter. The experimental results provide data that pull up leather and vegetable leather which are used as layer coverings for cardboard have a noise intensity below 75 dB, a safe category that reduces noise based on WHO and can be used as a noise reduction. Another discovery is that pull-up leather absorbs better noise than vegetable leather. This research provide new perspective on noise reduction materials using chrome-tanned leather (Pull-up) material.
