There are always complaints about sound levels in cinema, but it seems IMAX is really notorious there. I guess it's part of their concept - the largest picture, the loudest sound.
The problem with the loudness isn't so much the overall decibel level as it is the shitty EQ and upper frequency ranges playing at 120db.

Sub-bass audio at 120db can be really freaking great especially if the movie theater's sound system is truly up to the challenge and it is EQ'ed properly. That kind of sound isn't painful to hear at all even though it can be startling, like if it thumps the air in your chest.

High frequency audio at 120db is fucking painful. I might as well fire off a full magazine of .357 Sig ammunition without warning anyone to put on the goofy ear muffs first.

The folks at IMAX (and some other theaters) seem to be a little foggy on these differences in how sound in different frequency ranges is perceived at different decibel levels.

How about bad EQ and an overall shitty sound setup?
Or even just a 1930s picture palace auditorium with shitty (if you're trying to play multi-channel, full range audio) acoustics?

I wish I'd had a dB meter in the Denver UA screen when we saw Interstellar last November. It was freakishly loud, ruffled the pantlegs, and did so without being particularly garish or strident. It was tempting to cover the ears but I never felt compelled to give in. The room acoustics were dead, dead, dead, and the speakers were obviously not just well-tuned but used more tolerable horns than some. And the subwoofers had below-30-Hz dynamic range that I haven't heard since.

It can be done, but that takes some seriously good engineering. Too bad it's the exception.

In all fairness, a small follow-up from yesterday's "Jurassic World" in IMAX 3D. Sound level was quite pleasing. It was loud, but not deafening like Avengers and Tomorrowland were. This time I moved 6 rows further back, compared to sitting on the 4th row from the screen.

It's interesting how 3D seems to miniaturize things on the screen.

There are always complaints about sound levels in cinema, but it seems IMAX is really notorious there. I guess it's part of their concept - the largest picture, the loudest sound. The idea is not to faithfully reproduce, but to impress, so people consider IMAX as 'special'. And of course it's targeted primarily at younger audiences, which tolerates higher sound levels in general (or lost their hearing already on techno raves). And it's true, IMAX local staff has no means to reduce the sound level.
I've mentioned the same right here before. Their concept, at least with the thing we now call "Xenon Digital" is to impress, not to achieve the best possible quality. It's like those parties or concerts, where the sound is far too loud and lots of flashy things are happening, which distract you from the fact that the actual product, the music, is mediocre at best.

Interstellar was just an awful mix. If you played this thing at 7.0 in a well calibrated room, you gave about 90% of your audience an unpleasant ride. I know a theater which faithfully played it at 7.0, the experience was ear shattering and just... well, stupid. It was a string of WTF moments... If that's what the director intended, then be it, but I know for sure it's not what the audience wanted.

This is a common problem with 3D. I really noticed this the first time I saw an IMAX 3D 15/70mm movie. The image filled my peripheral vision, but it didn't seem BIG anymore. A 2D image thrown onto a giant screen can really have some great sense of scale, provided it has the image resolution 15/70mm can provide. Add 3D and the scale of the big screen is totally lost.

Some movies go too far with exaggerating the effect of 3D. That's what really creates that miniature effect. I laughed at a few scenes of the first Avengers movie, which I saw in 3D. During the big climactic battle it looked like little toys had come to life and were fighting each other.

The 3D issue has a lot to do with perspective need. For something to come in front of the screen you need background all around it. If the object that is suppose to come out goes beyond the screen edge it is effectively blocked by the screen plane.

@William: Think about it. You may actually think you want 'Level 7'. But you never know how loud an actual presentation has been played. I think you are right when you want a movie to be played louder. But don't insist on 'Fader 7'. You could regret it quickly. Hundreds of people (=individual human beings) sitting dispersed in a large room. You can never get it right for everyone. A single number can never express the complexity of sound-track,sound-systems, room, and individual perceptional aspects.
I want it played at the level it was designed to be played back at and was mixed for.

If the film's distributor said to play it at level 7, I want to hear it at level 7.

I recall when Twister was released there was a "warning" letter posted on the ticket booth stating that WB asked for it to be played a certain amount (I don't recall how much) over reference level.

The theater did, and it was magnificent at that volume.

Yes, I know 120 dB or louder can be very uncomfortable, but in brief bursts for effect it's fine.

If that's what the film makers intended, that's exactly what I want to experience.

I don't know if the Regal Colorado Center IMAX played Interstellar at fader 7 as instructed, but it was very loud… and very effective. Other showings I went to at other theaters where it was quieter just lacked the same impact.

Perhaps it should be advertised and left to ticket purchasers whether to view a film at the proper presentation level advised by the filmmakers or at whatever level the exhibitor feels is appropriate; to me that decision is no different than when US movie studios decided to hack up Sergio Leone's films for domestic release.

Oh, and as I mentioned, I donned ear plugs and wandered into the Ultra Sheer Dance Club located across from the AMC Westminster 24 on a Friday night and found the dance music within hitting 130+ dB with frightening regularity.

William

You're incorrectly assuming that the sound in your cinema will be exactly the same of the mixing room.

It is not. It may be louder, softer or even simply more distorted - as most of the cinema do not invest in sound systems with a good dynamic headroom on top.

I want it loud too and I too reckon that stick the volume to 5.5 for everything is not good.

But you don't want 7.0. You want the proper level. How this level is determined is down to the skilled projectionist on site.

Keywords: skilled and projectionist. That's it.

That said Interstellar was stupidly loud on Low Frequencies. I saw it in Leicester Square, it was loud as I would expect but some long and loud LF sequences were just annoying.

William, I'm not convinced you fully understand juuuust how loud and painful fader 7 can be with the average movie in the average(poorly tuned) multiplex.

As has been said, the director assumes perfect auditoriums and that's just so rarely the case. Not to mention the directors own bias having heard it a hundred times.

I am certainly uncomfortable at 7, unless things are just right. I was at a Dolby Cinema opening weekend of Tomorrowland, that I'm pretty certain was at 7 since it was opening weekend... It was..... just barely tolerable. Trailers were not. And this was in a very big auditorium. I saw a dozen people get up presumably to complain. But I stuck tight and tolerated it, didn't have a headache afterwards probably thanks to a fresh tune.

Forget IMAX screens though... I have a headache 20 minutes in every time I make the mistake to visit one.

Pretty sure directors don't intend pain.....

Assuming reference at my San Andreas viewing a week later in the same Dolby Cinema... It did work very well for that.

loudness is like temperature. It's unlikely to please everybody.

I like when it's loud if the room is well equipped and tuned. I am not an IMAX fan and I do not particularly like their sound but every time I've been ripped off by them for a show I've always enjoyed the level the film was run.

You also need some skills to properly adjust the level. The average manager/projectionist would step in the auditorium from a quiet foyer while Hulk is knocking down a building to then say "it's too loud!".

I've recently begged a friend to turn Avengers up from 5.2. It sounded great at 6.5 (and at 7.0 too but did not want to push my luck too much!). Once I persuaded them to sit in the middle of the auditorium with the fader set to 6.5, they were surprised that it did not sound too loud.

There are many variables. Setting 7.0 because Dolby say so is a mistake. Set it to 5.0 because the occasional customer complains, is a mistake too.

Unfortunately there are very few cinemas running their features at more than 5.5 nowadays.

See, that's just it.

I trust the sound designer and director more than I do a skilled projectionist.

Add that you go on to say that you found the LF sequences just annoying… but by turning those down you've affected what the sound designer and director were shooting for just as much as if you put a colored filter over the lens because you thought the film's coloring needed warmth.

I agree that auditoriums and EQ vary which is why, once again, I miss THX theatres and TAP (though the program is still around, membership is way down as especially chains didn't see the point when they could "do it themselves" via ETX and RPX) - at least with THX reference level a THX mastered film would mean 120 dB on the soundstage should be 120 dB in the theater. (I wrote letters to the editor of the local paper when some complained the new neighborhood theater was too loud when it was THX certified, pointing out they should complain to Hollywood, not theater management, as for once the movies were being presented as intended. IMHO, if you want it adjusted from intended, watch it at home in a few months.)

That's why when I visit a real IMAX theater, I note it's loud, but I also think "finally, a theater that gets it and plays films at their proper volume level."

That kind of leads to a side question - with the brightness levels Dolby Cinema will be able to achieve with HDR, will projectionists turn down the lamp levels if they get complaints the picture is too bright - even if that's what was intended?

Were David Lean making Lawrence of Arabia today, he might well use HDR to provide light levels for desert scenes one was forced to actually wince to view in a theater to accurately portray just how bright the daytime sun is in the desert.

If, the next time you take a commercial flight, the pilot decides to apply full power and climb off the runway at a 70-degree angle into a thunderstorm and a howling gale, would you be fine with that, because the pilot is operating the aircraft within its on-paper specifications and in a way that (s)he is qualified to do? Would you trust the pilot more than the passengers who would feel very uncomfortable on such a flight, and would probably choose a different airline next time (after first whining to the Daily Mail about how they thought they were about to die)?

I've now met a couple of prominent Hollywood directors, and dealt with the PAs of several more. For some reason, they all seem to want movie sound played at a volume that 99% of the moviegoing public, and movie theater workers, would find somewhere between uncomfortable and distressing. For rental, festival and other gala screenings their word goes and we have to do what they say: the result is usually multiple complaints from audience members.

For the other shows, we turn it down, not because we claim to know better than the filmmakers, but because the majority of our paying customers want it that way.

Which tells you people will complain about everything.

The fact that the sound is "too loud" at galas and premieres tells you one important thing – it's supposed to be played at that level, and was designed to be played at that level.

Of course I would trust the pilot more than the professional flying a plane within its capabilities; in the case of pilots and sound designers, I trust the experts, not random people off the street.

A good chunk of the paying public wants to check their cell phones and Facebook pages during movies too; is that okay because the public wants it?

Well of course not, you might say, because they're disrupting the enjoyment of other patrons. Well that's the way I feel when the movie isn't played at the level the sound designer had intended.

William, you do not understand 'loudness' at all. A single number can not express the variations of all existing auditoriums in the world.

The sound engineers or directors do NOT mix to 7, but they mix to what they find is appropriate and catching on the sound stage. Obviously, you don't understand that what they are judging is not fader setting, but perceived loudness. 7 means nothing when it comes to perceived loudness.

I you believe a typical IMAX presentation is compliant with the sound mixers or directors intention, then you are dreaming. Aside from that, if a movie has been mixed in ATMOS, Auro 3D, 5.1 and 7.1, what do you believe is the directors original intention? Did you ever watch an ATMOS released movie in an IMAX theatre? Why?

If you'd compare the sound level of an IMAX presentation with a level 7 presentation in a non-IMAX theater, you will notice the IMAX presentation is much louder. Also, for IMAX presentations, it is not the director or film sound engineer who decides about the level, but an IMAX sound engineer. Why do you ignore the directors loudness intention for IMAX presentations?

If you think that too many movies are played too soft in general, and that playing them too soft is bad, I am with you. But to insist on 'Fader 7' is just plain stupid.

A recent SMPTE study group came to the conclusion that traditional auditorium calibration to reference level shows large variations - they went out to a lot of very different cinemas and sound stages and did comparative measurements.

Fader 7 is a rule of thumb, nothing more, nothing less. It's good to have it, but it's wrong being slaved to it.
