A Noise Reduction Coefficient – commonly known as NRC – is a single number rating which represents the average of sound Absorption Coefficients of a material at specific mid-range frequencies (tested at 250, 500, 1,000, and 2,000 Hz octaves). The purpose of an NRC rating is to provide...
Noise estimationCorrelation coefficientThe paper presents interference estimation method involving search for "flat" area, on the basis of image analysis taking into account correlation coefficient and knowledge of variance reduction coefficient for noise in the filtered area. The proposed method was tested...
(>95%), and bulk structure, have shown vast perspectives in the field of traffic noise reduction23,24,25,26. A few polymer-based nanofibrous noise-absorbing sponges have been successfully constructed and show enhanced noise absorption properties (e.g., noise reduction coefficient (NRC) of 0.41...
After a signal is processed in the feed-forward and feedback paths, the noise suppression filter estimator then outputs a filtering coefficient signal to the filter for filtering the noise out of the speech and noise digital signal. 展开
the absorption peak of the composite materials is located at 1 000 Hz.The sound absorption performance of the 46-mm thick sample of plywood-foam composite is the best.Its sound absorption coefficient can reach 95.5%.The noise reduction coefficients(NRC) of the composite materials are also ...
temp_coeff_nonstationaryThe temperature coefficient to apply to the sigmoid function in the non-stationary noise mask. prop_decreaseThe proportion of decrease to apply to the mask. Choosing between Stationary and non-stantionary noise reduction ...
Unlike previous approaches to modulating mean and noise in gene expression, our method does not require the use of a particular genetic part or circuit, a specific mechanism of noise reduction or amplification, or a particular host organism. Rather, it only requires the availability of orthogonal ...
An input spectrum and a noise spectrum are detected in real-time and then noise reduction is achieved by subtracting the detected noise spectrum from the input one. This system requires the noise subtraction coefficient in order to reduce the difference between the detected noise level and its ...
