Blue Tree Publishing Audiogram of Everyday Sound Poster 24x36inch, Speech Banana, Waterproof, Show Frequency, Pitch and Ear Infomation

Extremely high quality. Printed on some type of plastic sheet. Very impressed.

The speech banana itself is positioned about 10 decibels too high compared to all other charts I've seen. But overall the poster is made of good material, has interesting illustrations, and it will help make my learning more enjoyable. I might use it in the future to explain hearing loss to patients...unless Blue Tree Publishing deems it appropriate to print a more agreed-upon version before then.

I love the look of these. I bought two for my office and I am impressed with how bright they are and the fact that they are laminated so they won't tear like a regular poster would. Great item!
