Presented in this paper is a revolutionary deep learning-based architecture for reducing the noise generated during Magnetic Resonance Imaging (MRI) scans. The proposed differs from usual adaptive algorithms used Active Noise Control (ANC). In present work, we are exploring use of Deep Convolutional Artificial Networks to recognize advanced sounds. By applying DL-NN 513-time segment, 180-degree...

Introduction: Noise is one of hazardous agents of workplaces in industries. Electric industries and power plants are among industries in which noise pollution should be taken into account. This study aimed to develop and verify a statistical model for acoustic wave propagation in an indoor environment for noise related risk reduction management. . Material and Method: This theoretical-experime...
