What is the rainbow passage? How does it relate to our industry. During the face fit testing process the mask wearer completes a series of exercises. These exercises test the seal of the mask and whether the mask fits the wearer. The fit test protocol should include a minimum of 7 exercises. The rainbow passage features in exercise 5.

It reflects the variety of sounds and mouth movements used in standard, unscripted English speech. Quite often used by language therapists. It contains nearly all the sounds of the English language. It contains nearly every letter of the alphabet. Below is the rainbow passage. Can you see which letters of the alphabet are missing?
