Physics Classroom is making strides to make our site accessible to
everyone, and features many accessibility features.
Our site contains 6 navigation areas. The Primary, Secondary,
and Page Level navigations have a screen reader version of their nav
structure that allows using the left and right keys to navigate sibling
navigation items, and up or down keys to navigate parent or child
navigation items. The others can be navigated using tabs.
Within the main content, we leverage headers to provide in page or
in tool navigation.
Although we are still rebuilding our content to leverage these tools,
our images should have both short and verbose descriptions, the later
describing in great detail the image for those who cannot see. Any
formulas found within the images are often in the image figure below the image.
Equations and formulas are rendered using MathJax, which has both verbal,
braille (including nemath braille), and keyboard navigation within them.
Learn how to configure and leverage this for various screen readers on our
Equation Navigation Page.
While not every area of
Physics Classroom is usable purely from keyboard and screen reader, we
are committed to continue work on making this possible. If you have
questions or need additional help, please use

Sound Intensity and the DeciBel Scale Video Tutorial
The Intensity and deciBels Video Tutorial explains what sound intensity is and how it is dependent upon distance from the source. The concept and mathematics of deciBels are presented with several examples to illustrate how the deciBel scale works. Numerous examples, illustrations, and animations assist in the explanations.
The video lesson answers the following questions:
What is the relationship between the intensity of sound and distance from the source?
Concept Builders, Waves and Sound Chapter - DeciBel Scale
Need practice with deciBels? This is the place to visit. You will find a collection of problems like those from Slide 7 of the presentation. Great practice is waiting for you.
The Calculator Pad, Sound Waves Chapter: Problem Sets SM6, SM7, and SM8
The equation for calculating the deciBel rating as described and used on Slide 8 may require that you provide yourself with additional practice. Our Calculator Pad is a great place to get it. Test your problem solving ability with one of our three problem sets.
Minds On Physics, Sound and Music Module, Mission SM3 -Sound Intensity and deciBel Levels
A Minds On Physics mission will always give a student a strenuous workout in close reading, critical thinking, and conceptual reasoning. When you feel students have a grasp of the concepts, it's time to test their understanding with a MOP mission. This particular one is closely correlated to the video. Use it with Task Tracker and grab student scores after the due date.
Concept Builders, Waves and Sound Chapter - DeciBel Scale
Do your students need practice with deciBels? This is the place to send them. You will find a collection of conceptual questions like those from Slide 7 of the presentation. Great practice is waiting for you. And if you have a Task Tracker account, you can make it an at-home assignment and gather the schools when the assignment is over.
The Calculator Pad, Sound Waves Chapter: Problem Sets SM6, SM7, and SM8
The equation for calculating the deciBel rating as described and used on Slide 8 may require that students have additional practice. Our Calculator Pad is a great place to get practice problems with immediate feedback and multiple opportunities for correction. There's three problem sets with varying degrees of difficulty ... something for every one. Check it out!
Science Reasoning Center, Sound Waves Chapter: Sound Intensity and the deciBel System
A Science Reasoning Center activity is a great place to sharpen students' science process skills. They will learn to interpret data and read graphs and draw conclusions that are supported by evidence. This activity is all about the same topic as the video. And if you like this one, you will find another activity on the equal loudness curves and the phon scale.
