Is there no chapter text for this?

Stacy, It is in "Assessment" Section. Do you have teacher access to the website? Probably, it is not visible for you.

Hi - I don't see the chapter text within any section here, including the Assessment section. Is there one available for this unit?

Elinore, Sorry but we do not have texts for the following chapters.

That is too bad - I find the texts very useful. I hope are able to post one in the future!

Sound Presentation: Embedded question #10 should be 28.3 Hz (not 48.3 Hz as posted). Thanks :)

You are absolutely correct. A new presentation will be uploaded with the correct frequency.

New presentation is posted.

In the pdf files of the lecture notes, many of the images are turning black background and are incredibly hard to see. Would it be possible to get a fixed pdf with the images visible? Thanks!

Michelle - thank you for pointing out the error. We have re-ran the file through our PDF converter and the black boxes and background are gone. - Melissa
