Ultrasonography is a medical imaging technique that uses high-frequency sound waves to create images of the inside of the body. It is used to diagnose and monitor a variety of medical conditions, including pregnancy, abdominal pain, cancer, heart and vascular disease, and musculoskeletal disorders. Ultrasonography can also be used to guide minimally-invasive procedures such as …
Echocardiography is a type of medical imaging that uses ultrasound waves to create images of the heart. It is used to diagnose heart disease and evaluate the structure and function of the heart. The images obtained from echocardiography can show the size and shape of the heart chambers, the thickness of the heart wall, the …
Non-destructive Testing: Ultrasonic waves are used to detect cracks, flaws and other defects in objects without damaging them. Medical Imaging: Ultrasound is used in medical imaging, such as echocardiography, to view the inside of the body. Cleaning: Ultrasonic waves are used to clean jewelry and other delicate items. Communication: Ultrasonic waves can be used to …

Infra sound is sound that is lower than the human hearing range (below 20Hz). It is usually felt as a vibration, due to its low frequency. It can be produced by natural events such as volcanic eruptions, earthquakes, and avalanches, as well as man-made sources such as industrial machinery and explosions. Ultra sound is sound …

Increase the absorption of sound in the room: Adding acoustic paneling to the walls, ceilings, and floors can help reduce the reverberation and potential echoes. Install sound-absorbing materials: Carpeting, draperies, and other soft materials can help absorb sound waves and reduce the amount of sound reflected. Use acoustic diffusers: Acoustic diffusers are designed to scatter …
The acoustics of a building refers to the sound quality within a given space and the ability of sound to travel within the space. Different materials and building elements affect the acoustics of a building. For example, hard surfaces such as concrete or tile will reflect sound, while softer materials such as carpet or acoustic …

Echo in sound is an auditory phenomenon in which sound is reflected off of a surface back to the listener, creating an echo. This effect can be heard in nature, in buildings, and in other enclosed spaces.
Persistence of audibility The persistence of audibility of a sound depends on the environment, the type of sound, and the volume. In a quiet environment, a very loud sound may persist for several seconds, while a softer sound may not be audible beyond a few milliseconds. In a noisy environment, the persistence of audibility is …
Reverberation is a phenomenon that is caused when sound waves reflect off of surfaces, creating a series of echoes that blend together and create an ambient sound. The sound waves can reflect off walls, ceilings, and other objects in an environment and create a reverberating effect. The time it takes for the sound to be …
