| sound, and introduces a subtle amount of reverb, so the sound
| matches the spatial environment shown onscreen.

| That's not the half of it. For many scenes and pretty much every
| scene outdoors, they use ADR, which means the actors went into a
| studio and recorded their lines dubbing over their lip movements
| on film. Not to mention foley artists recreate every footstep,
| door open/close, etc - very little of that is natural in a
| hollywood film.

| The original Bruce Lee movies were groundbreaking acoustically.
| Whoosh, whep whep, waaaaaauuuuu yaa!

| I skimmed the article briefly and didn't see this mentioned, but
| it was pivotal in the advancement of architectural acoustic
| design: https://en.wikipedia.org/wiki/Wallace_Clement_Sabine
|
| _Sabine tackled the problem by trying to determine what made the
| Fogg Lecture Hall different from other, acoustically acceptable
| facilities. In particular, the Sanders Theater was considered
| acoustically excellent. For the next several years, Sabine and
| his assistants spent each night moving materials between the two
| lecture halls and testing the acoustics. On some nights they
| would borrow hundreds of seat cushions from the Sanders Theater.
| Using an organ pipe and a stopwatch, Sabine performed thousands
| of careful measurements (though inaccurate by present standards)
| of the time required for different frequencies of sounds to decay
| to inaudibility in the presence of the different materials. He
| tested reverberation time with several different types of
| Oriental rugs inside Fogg Lecture Hall, and with various numbers
| of people occupying its seats, and found that the body of an
| average person decreased reverberation time by about as much as
| six seat cushions. Once the measurements were taken and before
| morning arrived, everything was quickly replaced in both lecture
| halls, in order to be ready for classes the next day._

| As a sound guy, I've always been into acoustic architecture. It's

| of the backlash against open office it's gotten a lot more
| attention (as the article mentions).
|
| But this being Hacker News, I want to complain about the most
| annoying trends in acoustic architectural design: Restaurants.
| I've noticed over the last ~10 years up-scale restaurants
| designing their spaces to be extremely "live", IE not much sound
| dampening so the place echoes amongst the concrete walls. The
| idea is that it sounds like so many people are there and it's
| really happening, because with even with two tables it can sound
| full. But so hard to have a conversation!
