acoustic sensing

Acoustic sensing involves using sound waves to detect and analyze objects or environments. Sensors emit sound signals, which bounce off objects and return as echoes. By examining these echoes, the system can determine characteristics like distance, shape, and material properties. This technique is used in various fields, including medical imaging (ultrasound), underwater navigation (sonar), and structural health monitoring. Acoustic sensing provides valuable insights without invasive procedures, leveraging the way sound interacts with different surfaces to reveal information about surroundings or internal structures in a non-destructive manner.
