This is one of the first long term follow - up studies of
aircraft noise so it's not possible to draw conclusions about cause and effect at this stage until more evidence / studies become available, say the researchers.
The Department of Transportation (DOT) Air Carriers Access Act (ACAA) establishes a procedure for modifying pet policies on
aircraft to permit a person with a disability to travel with a prescribed emotional support animal,
so long as they have appropriate documentation and the animal is not a danger to others or does not interfere with others (through unwanted attention, excessive
noise, blocking aisles, inappropriate toileting, etc.).
