Do noise cancelling headphones make the user talk quieter?

[WorksTheDinerAllDay]

Could anyone advise please? If, say, someone happened to live with a man who felt the need to project his voice on every damn video conference call, would noise cancelling headphones make him quieter? I've never used them, but I'm thinking that when you put your fingers in your ears it makes your voice seem loud?

Asking for a friend. Thanks.

I don't think so - I have some which I use on the tube, planes etc (in pre Covid times anyway!) and if anything it makes me shout as it puts you into this weird soundless bubble and it's hard to gauge your own volume. That being said I am quite softly spoken normally so maybe on someone more, er 'exuberant' it would have the opposite effect?

My sympathies to your 'friend', I too live with a 'boomer' and 6 months into working from home with him in a relatively small house and having to listen to every last word of his team calls, arguments with his boss, client calls etc I am also sick to the back teeth of it - he seems totally unaware he's doing it and is mildly surprised when I tell him he needs to drop his volume a bit, saying 'but I can't hear you at all' well of course you can't you idiot, some of us don't shout their way through every last call! And breathe... my only suggestion is get the noise cancelling headphones but for yourself, it doesn't exactly cancel out other people speaking exactly but reduces it to more of a fuzzy background noise which is infinitely less distracting!
