I am no stranger to loud movies, but has anyone else been turned off by the obnoxiously loud audio in ultra avx screening rooms? I just saw iron man 3, and measured 115 db with an spl meter. eek.gif
The base was really powerful (in a good way) but everything else seamed way too loud (especially the mid-high frequency sounds)
Ive contacted cineplex, and so far nothing in response. mad.gif
Sorry I wasn't sure what forum to put this in, if anyone wants it moved just say so...

Hi,

Not here to disagree your opinion of it being 'too loud'. If you did not know, reference level - which some cinemas run their volumes at - reflects the volume the piece/film is mastered at at the studio. To playback at this level the system needs to be capable of 105dB for mains and 115dB for the LFE - approximate maximums. See below I pulled from another forum:


"Reference level is the volume at 75db (decibels) in your room using full band pink noise. When you set up your system and you run pink noise through your speakers one at a time setting each level using an SPL meter to 75db you will (after all channels are done) and your volume control is set to 0db you will achieve "reference" when playing back movies or music. Movies will tend to reach peaks of 115db with your system set up properly.

Playing back at this level, with a correctly equalised & delay set room, with reverb/resonance times, etc should replicate and mimic the feature as the audio mixer of the film, together with director, producer intended.

Correct me if I am wrong, but is IMAX not reference level? I Saw Star Trek Into Darkness in IMAX 3D at the Universal Studios Cineplex and it was definitely not as loud as the AVX movie...

Cinepex ended giving me 35 dollars in popcorn passes, so its all good biggrin.gif

Higher distortion at a given spl tends to be perceived as louder. This might at least partially explain what you heard. Not all "reference levels" are the same.
