The FAA is concerned that some noise-canceling headsets might prevent pilots from hearing audible alarms, abnormal engine noise or other mechanical sounds. The agency, in a January 1 Information for Operators (InFO 07001), said noise attenuation of headsets “may vary by make and model” and if these sounds cannot be detected “discontinue the use of noise-canceling headsets.”
