My other half tends to get overcarried when Thameslink trains skip stops on the way to Brighton, because she has a hearing impairment that makes it difficult for her to hear ad-hoc PA announcements. I've occasionally wondered if an alternative way could be found to alert passengers, perhaps a means of registering for text alerts of last-minute schedule changes to a specific train.
I have a similar problem, hearing loss and tinitus mean train announcements are a real problem for me. I can hear someone is talking, just cant make out the words, compounded by the general train noise and less than perfect PA systems. This is then made worse by the general drone of spam announcements, warning me rain is wet, there are gaps at platforms, I must have a ticket, and to text a number if I see anything etc.
I kniow this has been covered before, but it is a real problem for those with hearing impairment. Firstly hearing aids only help to a point, if there is a lot of background noise or the input sound is distorted (typical ropey train PA) then they just make the noise louder, remember rubbish in = rubbish out.
If I know I need to listen I can concentrate, but look up something called Hearing exhaustion, fine for one announcement, not a solution for the usual drone of rubbish, so I tend to switch off and resort to noise cancelling ear buds, particularly on a long journey.
On a recent (last weekend) 30 minute journey back from Scarborough there were about 15 minutes of drone, to the point where a conversation with my wife was impossible.
What could be done:
Remove the drone of spam announcements, only announcements relevant to the current journey should be made "This train is for XYZ, the next stop is ABC", "We are approaching ABC", and "This train calls at ..."
when stopped at a station, are fine anything else should not be made.
Preceed anything out of sequence which needs immediate passenger reaction or conveys immediate information with a bing bong sound, similar to that used on SNCF, it gives those of us with impaired hearing time to switch on mentally and concentrate. Anything else should be relegated to the displays at the end of carriages, with a hearing loop and audio backup for those with sight loss. I can program my phone to recognise the bing bong sound.
Ensure that PA equipment is properly maintained and clear. Consider duplicating important announcements on the in carriage displays similar to closed caption displays, the software exists and is in regular use in other areas of our lives, its not rocket science, yes sometimes the words can get a bit jumbled, but generally sense can be made of it.
None of these things would cost vast sums of money, but would help hearing impaired people, and I think would improve the environment for everyone.
Text messages rely on a phone signal, Wi Fi where it exists could provide the message service to your phone, perhaps in conjunction with an app which 'listens' in the background. Its possible, just needs someone to develop and deploy.
Rather concerningly the ToCs dont seem interested, in spite of the potential safety implications.
