The pulse-echo technique is a method used to measure the distance to an object or the properties of materials by sending a pulse of sound and analyzing the echo that returns. This technique is essential in various applications, including architectural acoustics, where it helps in assessing sound absorption and reflection characteristics. The time taken for the pulse to travel to the object and back can provide insights into the speed of sound in the medium, which is crucial for understanding how sound interacts with different surfaces.
