Answer:

The correct answer to "Which property these panels are taking advantage of?" is B. Reflection because reflected waves bounce off a media.

Step-by-step explanation:

Part of a wave energy is absorbed by a solid through refraction and some is reflected off of the solids surface. An echo is a representation of reflected sound waves.

Echoes are minimized in theaters and performance venues. Additional panels are placed on walls and ceilings to help absorb and/or direct reflected sound waves in ways that enhance the audience's satisfaction of a live show.

Answer:

(b) Reflection because reflected waves bounce off a media

Step-by-step explanation:

You want to know the property of special wall and ceiling panels that is being used to direct sound waves.

Reflection

The properties offered in the answer choices are (1) reflection, and (2) absorption. Of these, the property most likely used is reflection.

Reflection causes the sound to bounce off the panel and move in a direction based on the angle at which it hits the panel. By angling the panels appropriately, the sound can be directed wherever it might be desired.

Absorption

Absorption will cause the sound to be "swallowed up" by the panel, so that the energy of it is lost in the panel and not returned to the air. An absorptive panel may also have a certain amount of reflection. In general, such a panel can modify the acoustic behavior of the auditorium, but will not "direct sound waves."

Additional comment

Often reflective panels are angled at more or less random angles so that sound is reflected around the room, but not to any particular spot. The purpose is to eliminate any echo in the room.
