| چکیده | ||
| آسیبهای ناشی از صداهای مزاحم و ناخواسته در کاربردهای صنعتی و خانگی بر کسی پوشیده نیست. اهمیت کنترل این صداهای مزاحم و ناخواسته بهویژه در کاربردهای خانگی محققین بسیاری را جذب این حوزه نموده است. در این پژوهش هدف بررسی تجربی کاهش صدای منتشر شده از یک ماشین لباسشویی عمودی خانگی میباشد. بدین منظور جاذبهای صوتی مختلف پیشنهاد و مورد بررسی قرار گرفتند. در این راستا، یک بانک داده بهوسیله نتایج حاصل از این آزمایشها ایجاد شده است. بانک داده فوق حاوی صدای ذخیره شده در چهار جهت ماشین لباسشویی در فاصلههای مختلف در حضور جاذبهای صوتی پیشنهادی میباشد. در روش پیشنهادی نخست تأثیر جاذبهای صوتی بر کاهش شدت صدا بررسی میشود. سپس در ادامه نحوه اثرگذاری جاذبهای صوتی بر سیگنالهای ذخیره شده در فضای زمان- فرکانس بحث میشود. نتایج حاصل شده حاکی از تأثیرپذیری مستقیم سیگنال ذخیره شده از جاذبهای صوتی مورد استفاده در تمامی جهات با شدتهای تقریباً یکسان است. کاهش شدت صدا در حضور جاذبهای صوتی مختلف متفاوت و میانگین آن 35/6 دسیبل بوده است. بهترین و ضعیفترین عملکرد، بهترتیب مربوط به الیاف فوتر و پلاستوفوم با کاهش 8 دسیبل (10 درصد) و 5/4 دسیبل (4/5 درصد) در شدت صدا گزارش شده است. علاوه بر این، آزمایشها نشان میدهد که استفاده از جاذبهای صوتی مناسب میتواند به طور قابل توجهی کیفیت زندگی در محیطهای خانگی را افزایش داده و مشکلات ناشی از صداهای مزاحم و ناخواسته را کاهش دهد، که این امر میتواند تأثیر مثبت زیادی بر کیفیت زندگی کاربران داشته باشد. | ||

| چکیده [English] | ||
| 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. | ||
