Signal integrity has become a critical issue in the design of high-performance circuits. Noise on a net arises both through propagation of noise from previous stages through the driver gate of the net and through injection of new noise through coupling capacitance with neighboring nets. Typically, propagated noise and injected noise are added linearly to simplify the analysis and increase its e...

The menace of noise is a by-product of civilization and its hazards are well known. Noise levels were measured in Karachi, at different places and at different times of the night and day, using an Amplaid noise meter. The leg for Karachi came to 80 dB (A), the General Noise Index x (G.N.I.) to 460, and the noise pollution level (N.P.L.) to 99 dB (A). These values are significantly higher (P les...

in recent years noise has been well known as an environmental pollution. particularly its effects will be more serious in some environments including hospitals which patients need a calm and peaceful condition. this study aims to evaluate hospitals noise pollution level. this study is a cross-sectional study. noise measurements were made in all hospital wards in a workday and weekend from 8 to ...

The outdoor noise levels from the various work places of the integrated steel plant were measured. The average noise level (L(eqst)) at the outdoor was found between 59-84 dBA. The combined noise level (L(eq)) of the plant was 90 dBA and 92 dBA on 1.12.2006 and 1612.2006, respectively. The noise levels in the far fields were found between 43-70 dBA for daytime and meet the noise quality for ind...

The harmful effect of the noise on human health has been known for many decades and it's first harmful effect on the hearing came to be known in the year 1831. According to the nature of the work, this di- sease was called Boiler Maker's deafness.  Noise due to the industrial machineries is one of the main cause of Environmental Poliution, and among the different industreis, Textile industry i...
