Ease of Use for Both Students and Faculty

Rating: 4 stars
Strengths: Sound Waves and Music is an excellent presentation of the physics of sound waves. The information is clearly organized into a progressive series of five lessons. The lessons begin with an introduction to the physics of waves followed by properties of sound waves, wave behavior, resonance and ending with musical instruments. The text is concise. The site includes animation and quiz questions to support the lesson material.
Concerns: It may be a little densely written for an introductory acoustics class for high school or college freshman music majors who may not have a strong physics background. This site works best if the student works through it progressively. Navigating through the site would be improved if the navigation column on the left side of the window remained stationary while scrolling through a given page. Breaking the text into shorter blocks and reducing the use of bold text on the animation pages would improve readability.
