Working with members from the Asia Pacific Cabin Safety Working Group (APCSWG), Dr Brett Molesworth and colleagues investigated the effectiveness of noise cancelling headphones in the cabin, in terms of intelligibility of the pre-flight cabin safety brief. 25 participants completed the research testing 5 different auditory conditions: noise cancelling headphones in the active state with audio brief played through headphones, noise cancelling headphones in the active state with audio brief played through external speaker, noise cancelling headphones in the passive state with audio brief played through external speaker, noise cancelling headphones with music and brief played through external speaker, no headphones with audio brief played through external speaker. The results revealed noise cancelling headphones without any conflicting audio signal aided in participants’ ability to hear and recall information.
The results of this study are presently under review in a peer review journal.
