Question

An auditorium has special panels installed along its walls and portions of the ceiling to direct sound waves. Which statement best explains the wave property these panels are taking advantage of?

1) reflection, because reflected waves have a higher intensity
2) reflection, because reflected waves bounce off a media
3) absorption, because absorbed waves go into the media
4) absorption, because absorbed waves have a lower frequency

Answer 1

The panels installed in the auditorium are taking advantage of the reflection property of sound waves.

Step-by-step explanation:

The special panels installed along the walls and portions of the ceiling of the auditorium are taking advantage of the reflection property of sound waves.

When sound waves encounter an interface between two media with different wave speeds, such as the panels and the air, reflection and transmission of the wave occur. The greater the difference in acoustic impedance between the two media, the greater the reflection and the smaller the transmission.

In this case, the panels are designed to reflect sound waves, redirecting them towards the audience to enhance the listening experience.
