- A. Medicine and healthcare
- B. Environmental conservation
- C. Social sciences and psychology
- D. Sports and recreation
Remarks:
Explanation:
Acoustics and technology intersect in various fields, with medicine and healthcare being one prominent area. Acoustic technologies are used in medical imaging, diagnostic procedures, hearing aids, and therapeutic applications, enhancing patient care and improving health outcomes.
- A. They amplified the sound.
- B. They prevented the deterioration of sound.
- C. They created harmonious notes.
- D. They increased the speed of sound.
Remarks:
Explanation:
According to ancient theories, the ascending seats in theaters were designed to prevent the deterioration of sound. By arranging the seats in an ascending manner, the sound waves could flow back and break up following waves, thus maintaining the quality of sound.
