It has been hypothesized that objective assessment for building acoustic conditions only may not always be representative of the users’ perception in occupied indoor spaces. This study objectively and subjectively examined indoor acoustic condition in rooms w…

Detection and localization of acoustic events in an environment are important to protect the military and civilian installations. While there are finite paths of wave propagation in simple or low reverberant environments, in complex environments (e.g. a compl…

In real life, when a noise problem occurs, it is important to identify the cause and measure the noise of the source, since it may affect human beings or other constructions due to vibration generated from noise, so it is necessary to determine the noise rela…
