What are the three types of acoustic panels?

The correct identification of the three types of acoustic panels is rooted in understanding how sound interacts with different surfaces. The types of panels can be categorized based on their primary functions regarding sound energy.

Reflection panels are designed to bounce sound waves back into a space, which can enhance liveliness and clarity of sound in certain environments, like control rooms or concert halls. Absorption panels, on the other hand, are effective in reducing sound energy by converting it into heat, thereby minimizing echoes and reverberation. Transmission panels, while not as common, can control sound that passes through walls or barriers and are used in spaces where sound isolation is important.

In a typical acoustic treatment scenario, you will find a necessity for strategies involving sound reflection (which can help manage room acoustics), absorption (to control excessive reverberation), and transmission (to ensure sound does not bleed into or out of desired areas).

Although options present various elements related to sound, the specific grouping of reflection, absorption, and transmission accurately reflects the different purposes these panels serve in acoustic treatment.
