The adverse effects of unwanted and disruptive noise in industrial and domestic applications are widely recognized. The significance of controlling such noise, particularly in household settings, has drawn the attention of many researchers to this field. This study aims to experimentally investigate the reduction of noise emitted by a vertical domestic washing machine. To this end, various acoustic absorbers were proposed and examined. A database was constructed using the results of these experiments, which includes recorded noise data from four directions around the washing machine at varying distances, in the presence of the proposed acoustic absorbers. In the proposed method, the effect of acoustic absorbers on noise intensity reduction is first evaluated. Subsequently, the impact of these absorbers on the recorded signals in the time-frequency domain is discussed. The findings indicate a direct influence of the acoustic absorbers on the recorded signals in all directions, with nearly equal intensity reductions. The reduction in sound intensity varied depending on the type of acoustic absorber used, with an average decrease of 6.35 dB. The highest and lowest performance were recorded for felt fiber and polystyrene foam, resulting in sound intensity reductions of 8 dB (10%) and 4.5 dB (4.5%), respectively. Additionally, the experiments show that the use of appropriate acoustic absorbers can significantly improve the quality of life in domestic environments by reducing unwanted and disruptive noise, thereby having a substantial positive effect on user well-being.
