No LUFS regulations are the reason you use subtitles to watch TV

Dynamic range and loudness normalisation are surely the main reason people are using subtitles, but habits are undeniably also changing too, as is the way people consume media in general.
People don't just look at the TV for an hour straight - they are doing other things, or second-screening, or having conversations, and multiple methods being available to pick up on the show dialog is helpful.
Let's not forget simple reasons like accessibility, either. My friend here in the UK is Hungarian, and despite being completely fluent in English he always likes to watch shows with subtitles as it helps with understanding some British accents which can be tricky for non-natives.
And people just process information in different ways. We've all heard by now that some individuals can be visually oriented, while other people are aural. If you get a choice, why not take it?
Not to mention that subs on streaming services are much better visual quality and timing than subs on broadcast TV used to be, which felt nasty and mis-timed, and very second-class. Clearly 'good enough' for hard of hearing individuals but not very pleasant.
I don't think it's a hot take to say that as accessibility features get better and more available, more people will use them. And accessibility is for everyone.
- I think you're missing the point. Lack of LUFS standards is what forces people that normally wouldn't/don't like to use subtitles to use them because they can't understand dialogue otherwise.
  
  I don't disagree with that.
  OP noted they posted this in response to this other post in memes which says "The majority of Milennials and Gen Z watch TV with subtitles on" - the point of this Tom Scott post being to say it's not actually a generational issue, it's about volume normalisation (or the lack of)
  I also agree it's likely mostly about volume normalisation, and my point is only that there are other factors at play also. We can't definitively say "volume problems are the whole reason people with normal hearing are using subtitles" because that dismisses a load of other contributing elements or ways the world has changed in the last few decades, as I mentioned in my previous comment.
  People aren't the same as they were 20 years ago and the world isn't the same either, with different behaviours, habits and preferences. There are lots of factors for subtitle use in hearing people, not just the (admittedly awful) volume.

  There are native Londoners from the west of London who have trouble understanding the native Londoners from the east of London and vice versa

  That's because the ones on TV are not subtitles, they are closed captions. They are transmitted differently (check out Technology Connections's recent video for more info) and serve different purposes.
  Also, for live broadcasts, they're actually being typed by a stenographer in real time, which is why they sometimes have mistakes.

  If you've seen subtitles lately, they used to be pretty bad but now they're horrible. The mess up on what's being said a LOT.
  Also they spell like a primary drop-out: till, your/you're, etc.
  
  You clearly don't remember the days of live close captions. Hoo-boy, it's like you could pinpoint the moments the transcriber lost their focus.

  Wouldn't this make subtitles less useful rather than more? You can't see the subtitles if you're not just looking at the TV. For second-screening, it would be more helpful to listen to the audio while you're also scrolling Lemmy or whatever.
  
  Audio and subtitles are complementary.
  If you're having a conversation, or doing some other task that makes sound, or scrolling social media and a video starts playing, there could be a noise that momentarily covers up the audio and you miss something. If there are subs then you can quickly glance to see what was going on.
  Listening to spoken dialog allows you to look away, but subs let you catch back up if you miss something. They cover for each other.

I really miss Tom Scott
- A new episode of Technical Difficulty popped up a day ago or so, if you want some jokes or hijinx.
- Glad he's moved on to doing things he likes on his own terms.
- He's working on a new youtube project
- Me too. Atomic Frontier is following a similar ultra dense respect-your-time videography-nerd polymath approach to YT.

- What happened to him?
  
  He mostly retired. He no longer posts videos regularly, though I think there's a podcast he's on.

Career Audio engineer chiming in here. I would say it's a combination of the lack of LUFS regulation and improper mixes. IMHO dialogue clarity should be prioritized more than it currently is, or at the very least we should use the center channel in surround sound formats exclusively for dialog to make it easier to adjust(via software and/or or av receivers), at least more than we currently do. Also modern TV shows are often mixed with a high dynamic range like a movie would be(which relates to LUFS levels), kind of silly and also IMHO bad mixing practice as most of your viewers don't have high end home theatres.
- What would be the alternative? You don't really expect the streaming companies to pay for TWO masters do you!? (/s if it wasn't obvious)
  
  I don't really have an alternative, just trying to give my perspective on the issue.

Naww dog I just don't speak Japanese
- Skill issue
  
  I better not catch you consuming any media that's been translated

Even with places like YouTube, where LUFS level is strictly defined, there's sooo many creators who have no earthly idea what LUFS is, which levels YouTube enforces, and how it corrects for it. They post their videos with quiet narration and wonder why viewers get annoyed at all of the turning up and turning down of volume on each video.
See, YouTube enforces LUFS on videos by reducing volume on loud videos down to -14 LUFS. But, it doesn't do anything to quiet videos. If you ever bring up the "Stats for Nerds" and look at the "Volume / Normalized" value, you might see something like "content loudness -5.9dB". That means it's -5.9dB quieter than it should be, and the creator should have amplified the video to normalize the volume levels before uploading it to YouTube.
So, you end up with a video that's about -6dB quieter, and you have to turn up the volume to actually hear the narration. Then your TV or whatever device you're watching will get blasted by the next video, which is properly normalized at around 0dB, and you're forced to turn the damn volume back down.
YouTube has finally started to acknowledge the problem by introducing the Stable Volume feature. But, really, creators should educate themselves on how to properly mix their audio. I know editing is hard and there's so many moving parts to deal with for YouTube uploads. But, audio quality is everything in a YouTube video. Nobody cares about whatever random B-roll video game footage, or PowerPoint slide presentation, or watermarked stock images, or videos of you presenting the narration with a lapel mic tied to a tree branch you're using on the video side. It's all about narration and audio quality.

Congenital hearing defect is why I use subtitles.
- I did not mean to prejudice. Sorry.

As I am getting older, I think i can't hear as well as before.
Bitter reality
- Try some old time TV shows to see if that's really the case. I don't have issues watching old Star Trek, but current shows are a shot in the dark.
