For those of you who've actually used it, is the ARRIFLEX 416 Plus HS louder than the regular speed range 416 models? The former is rated at 29 dB while the latter two are 20 dB. However, unless I'm misinterpreting the specification, I suspect the sound level measurement is referring to operation at the top speed (150 fps vs 75 fps). Or does it actually make more noise at standard frame rates like 24 fps?
