While preparing a presentation on ancient theater architecture, a student takes the following notes:
* The Roman architect Vitruvius wrote that ancient Greek theaters were engineered to optimize acoustic projection.
* In , physicists Nico Declercq and Cindy Dekeyser analyzed the acoustic profile of the Theater of Epidaurus, an ancient Greek theater.
* They found that the theater's limestone seats reflect sound waves at frequencies above , which amplifies the actors' voices.
* They found that the limestone seats absorb sound waves at frequencies below , which minimizes environmental background noise like wind or crowd rustling.
* The researchers concluded that the material of the seats acts as a selective acoustic filter, enhancing the intelligibility of performances.
The student wants to support the claim that the specific material of the Theater of Epidaurus's seats serves to improve the audience's ability to hear performances by filtering out background noise. Which choice most effectively uses information from the notes to accomplish this goal?
- The limestone seats of the Theater of Epidaurus absorb sound waves below , which suppresses environmental background noise like wind while allowing the higher-frequency voices of actors to be amplified.Cevap
- BIn , physicists Nico Declercq and Cindy Dekeyser conducted a study using sound propagation models to investigate the acoustic claims written by the Roman architect Vitruvius.
- CBecause the Theater of Epidaurus was constructed out of porous limestone rather than marble, it became the most famous ancient Greek venue for acoustic clarity, attracting audiences from across the Mediterranean.
- DThe limestone seats of the Theater of Epidaurus amplify all sound waves, including both high-frequency actor voices and low-frequency background noises such as wind.
