Don’t think it’s old people I think it’s more audio processing disorder which perhaps could happen to people later in life. All I know is I know people who have audio processing disorder and often times don’t realize it’s there phone because of how much noise is going around, all ages and all gender and sexes can experience this

I have it also and it’s incredibly hard for me to know who’s talking or my ringtone /notification even if it’s unique. With out my noise cancelling headphones with passthrough, every sound I hear all at once at all times, nearly impossible for me to differentiate between them
