The increased requirements in the field of military voice communications has resulted in a greater need for information on noise interference. This is especially true in the light of current emphasis on systems integration, wherein communications play such an important role. Efforts were made to determine the influence on speech communications of various forms of interference commonly encountered in sophisticated electromagnetic communications systems. A study on the masking of speech with shaped random noise is described. Harvard phonetically-balanced word lists were mixed with noise at five intensity levels and 11 frequency cutoff limits. Five well-trained subjects listened in isolation to the composite signal presented over headphones. Data are presented in both tabular and graphic form, showing the intelligibility remaining under each masking condition. Both high-pass and low-pass noise conditions resulted in complete masking at the lowest signal-to-noise ratio. An amplitude-related shift in the crossover points for the high- and low-pass masking functions was noted and is attributed to a downward spread of masking effect. (Author).

Additive and multiplicative noise in the information signal can significantly limit the potential of complex signal processing systems, especially when those systems use signals with complex phase structure. During the last few years this problem has been the focus of much research, and its solution could lead to profound improvements in applications of complex signals and coherent signal processing. Signal Processing Noise sets forth a generalized approach to signal processing in multiplicative and additive noise that represents a remarkable advance in signal processing and detection theory. This approach extends the boundaries of the noise immunity set by classical and modern signal processing theories, and systems constructed on this basis achieve better detection performance than that of systems currently in use. Featuring the results of the author's own research, the book is filled with examples and applications, and each chapter contains an analysis of recent observations obtained by computer modelling and experiments. Tables and illustrations clearly show the superiority of the generalized approach over both classical and modern approaches to signal processing noise. Addressing a fundamental problem in complex signal processing systems, this book offers not only theoretical development, but practical recommendations for raising noise immunity in a wide range of applications.

The process of suppressing acoustic noise in audio signals, and speech signals in particular, can be improved by exploiting the masking properties of the human hearing system. These masking properties, where strong sounds make weaker sounds inaudible, are calculated using auditory models. This thesis examines both traditional noise suppression algorithms and ones that incorporate an auditory model to achieve better performance. The different auditory models used by these algorithms are examined. A novel approach, based on a method to remove a specific type of noise from audio signals, is presented using a standardized auditory model. The proposed method is evaluated with respect to other noise suppression methods in the problem of speech enhancement. It is shown that this method performs well in suppressing noise in telephone-bandwidth speech, even at low Signal-to-Noise Ratios
