Noise impact is the most sounds are subjective evaluation, hearing, and can significantly affect human health and wellbeing. The effects of noise on the human body include hearing loss, impaired growth and development, overall tension, and sleep disturbance in children and adolescents, and decreased ability to the building environment safety. Although it is difficult to classify the specific effects of noise, noise affectless is also considered by many ecologists to be destroying or eliminating, and pollution plays an important role. FPGA (field-programmable gate array) is used to measure and estimate the instantaneous amplitude of environmental noise and uses advanced architecture for picking up noise-polluted audio signals. A high-performance algorithm refers to the number of arithmetic operations (multiplication, division, and addition) noise value are calculate the output value of a system. Memory Requirements Specifies the amount of memory needed to store system parameters, past input, output past, and any intermediate calculated values. The effect of limited accuracy means that the quantitative effect is inherent in the implementation of any digital system. High-performance algorithm technique for cancel the noise in the desired signal. Environmental noise must be correlated with the noise component of the audio signal in order to be positively correlated and effectively removed.

噪音影响最大的是对声音的主观评价，听觉，并且会显着影响人体健康。噪声对人体的影响包括听力下降，生长发育受损，总体紧张以及儿童和青少年的睡眠障碍，以及对建筑环境安全性的降低。尽管很难对噪声的具体影响进行分类，但是许多生态学家也认为无影响的噪声正在破坏或消除噪声，污染起着重要的作用。FPGA（现场可编程门阵列）用于测量和估计环境噪声的瞬时幅度，并使用高级架构来拾取受噪声污染的音频信号。高性能算法是指算术运算（乘法，除法，噪声值计算系统的输出值。内存要求指定存储系统参数，过去的输入，过去的输出以及任何中间计算值所需的内存量。精度有限的影响意味着定量影响是任何数字系统实施中固有的。高性能算法技术，用于消除所需信号中的噪声。环境噪声必须与音频信号的噪声成分相关联，以便进行正相关并有效消除。精度有限的影响意味着定量影响是任何数字系统实施中固有的。高性能算法技术，用于消除所需信号中的噪声。环境噪声必须与音频信号的噪声成分相关联，以便进行正相关并有效消除。精度有限的影响意味着定量影响是任何数字系统实施中固有的。高性能算法技术，用于消除所需信号中的噪声。环境噪声必须与音频信号的噪声成分相关联，以便进行正相关并有效消除。
