Specific Objectives
At the end of this course, students will be able to understand the definition of sound and its historical development, recognize the importance of acoustic comfort in buildings, and identify the physical characteristics of sound such as frequency, amplitude, wavelength, and sound propagation. They will also be able to relate these concepts to practical applications in architectural acoustics, improving sound quality and ensuring a comfortable acoustic environment.
