SciShow: 5 Ancient Structures with Amazing Acoustics

Teacher or professor: SciShow
Subject: Science
Content of the Lesson: Many ancient sites had some truly amazing effects on sound waves, suggesting that early cultures may have built spaces to evoke certain sensation. And by studying the acoustics of these structures, we can learn new things about the experiences people had there, hundreds or even thousands of years in the past.
