Chapter 5: Problem 64

Give two practical applications of reflection of sound.

Short Answer

Expert verified

Answer: Two practical applications where sound reflection is utilized are auditoriums and concert halls, where sound reflections are used to create a good listening experience for the audience; and sonar technology, which uses sound reflection to detect underwater objects and determine their distance.

Step by step solution

Practical Application 1: Auditoriums and Concert Halls

In auditoriums and concert halls, reflection of sound is crucial for creating a good listening experience for the audience. Architects and engineers rely on sound reflections to direct the sound from the stage to the various parts of the audience accurately, ensuring that everyone can hear the music or speech being presented. Acoustic panels, curved walls, and other design features are used to control and manipulate sound reflections in these spaces.

Practical Application 2: Sonar Technology

Sonar, which stands for Sound Navigation and Ranging, is a technology that utilizes the reflection of sound to detect objects underwater. The sound waves are emitted by a sonar device, travel through the water, and bounce back upon encountering an object, such as a submerged vessel or a school of fish. The time taken for the signal to return is used to calculate the distance to the object. This technology is utilized in various applications such as submarine navigation, underwater mapping, and oceanographic research.
