Record of reflected sound from the heart
WebbEchosounding is a basic type of seismic reflection. Echosounding is used to measure the depth of the water. High- frequency echosounders (12,000 Hz) are used to measure the depth to the seafloor. A sound pulse is sent from a ship and that sound reflects off the seafloor and returns to the ship. The time the sound takes to travel to the bottom ...

Webb3 mars 2024 · Citation, DOI, disclosures and article data. Reflection of a sound wave occurs when the wave passes between two tissues of different acoustic impedances and a fraction of the wave 'bounces' back. This forms one of the major principles of ultrasound imaging as the ultrasound probe detects these reflected waves to form the desired image.
