Airport Security and Hearing Aids
Many people question if it is safe to go through the scanners at the security checkpoints with their hearing aids. According to the TSA website, it is not necessary to remove your hearing aids, but you should inform the security officers that you have them. It is actually better to leave the hearing aid(s) in your ear(s) so that you can better hear instructions and answer questions from the Security Officers. If you still feel uncomfortable going through the scanners because of your instruments, you can ask for a full-body pat down. If this is the case, the security officer may ask to inspect your device if needed.
Always ask (politely, of course) the security officers to look directly at you so that you can better understand what they are saying to you. Simply explain you are hearing impaired and that it would be better if they could look directly at you. You should then have no problem going through airport security.
