Authentic Listening Material

I’ve been looking out for some authentic listening material for some of the Business English courses I teach. I just found a website called Freesound which has some fantastic Creative Commons-licensed MP3 and wav files, free to download.
I downloaded some basic train and airport announcements and I am planning to have false beginner students listen for answers to the following questions:

  1. When does the announcement change to English?
  2. Which gate can you board the plane from?

In another class I’ll have some pre-intermediate students listen for answers to these questions:

  1. What is the new platform for the Penzance train?
  2. Does the Penzance train stop at Exeter St. David’s?
