Collection context

How is a collection context set?

When you first open a Collection, the collection title page displays. When you land on this page, your browser saves a cookie that lets it know you are viewing that collection. After that, whenever you view a module that is included in the collection, you will view that module in the context of the collection, explained below. This is true until you land on a different collection's start page, at which point your browser will only display collection context information for modules in that second collection. Even if a module is actually included in 50 different collections by different authors, your browser will only show it in the context of the collection you are viewing.
To view collections correctly, make sure that you have enabled cookies in your browser.

Collection start page

Many portions of the collection start page are analogous to those when viewing a module, but some parts are new.

Table of contents

The Table of Contents is shown on the collection start page itself, and on any module viewed within the context of that collection. Click a module name to jump to that module. You can use the triangles next to each subgrouping to open and close sections of the table of contents, or you can collapse the entire Table of Contents to save space by clicking the small triangle at the top of the portlet.

Collection context bar

When you view a module in the context of a collection, there will be a collection context bar above the module title bar to remind you that you are inside a collection. Analogous to the module title bar, this contains the collection title, authors, and summary.

Previous or next modules

Once you display a module from within a collection, you can move to the previous module or to the next module in the collection byclicking the ≪Previous or Next≫ links that appear in the upper right corner just below the collection context bar .

can someone explain to me, an ignorant high school student, why the trend of the graph doesn't follow the fact that the higher frequency a sound wave is, the more power it is, hence, making me think the phons output would follow this general trend?
Joseph Reply
Nevermind i just realied that the graph is the phons output for a person with normal hearing and not just the phons output of the sound waves power, I should read the entire thing next time
Joseph
Follow up question, does anyone know where I can find a graph that accuretly depicts the actual relative "power" output of sound over its frequency instead of just humans hearing
