Definitions from the WebAcoustic ImpedanceDescription:Acoustic impedance is a physical property that measures the opposition of sound waves when they pass through a medium or encounter a boundary. It quantifies the ability of a material to transmit or reflect sound waves. Acoustic impedance is commonly used in fields such as physics, engineering, and acoustics. Senses and Usages:Sense 1: PhysicsIn physics, acoustic impedance is a measure of the resistance faced by sound waves when traveling through a specific medium. It depends on the density and the speed of sound in the medium and is expressed in units of ohms. Example sentence: The acoustic impedance of water is lower than that of air, resulting in different properties for underwater sound transmission. Sense 2: EngineeringIn engineering, acoustic impedance is an important parameter when designing acoustic systems or dealing with sound transmission. It helps determine the efficiency of sound energy transfer between different components. Example sentence: The acoustic impedance of the loudspeaker should match that of the room for optimal sound reproduction. Sense 3: AcousticsIn acoustics, acoustic impedance plays a crucial role in understanding the behavior of sound waves at different boundaries, including the reflection, transmission, and absorption of these waves. Example sentence: The acoustic impedance mismatch at the interface causes a significant reflection of sound waves, resulting in unwanted echoes in the concert hall. Related Products: | ||||
