Don't worry, once married, a man never has to worry about losing his mind.....because his wife keeps it locked away.
Try telling the world you want it loud and the wife is sitting there holding her temples with her family looking on. Now that's that's a picture no man wants going public so the guy simply says..."Yes dear."
Boo-hoo for all spouses wrapped up in this fashion.
Currently we're working on a compromise. To facilitate this compromise, my current backdoor research project is what are "REAL WORLD" SPL levels in movie theater houses as opposed to THX reference levels as MPAA standards are being changed to accommodate viewer demands.
Several points have come of this research; the MPAA has increased standards for trailers and commercials (not to be confused with television viewing standards), reducing SPL levels to that of main feature sound tracks (no jacking up the volume for trailers or commercials to get your attention), viewer satisfaction with slider 7 (movie house sound level standard) breaks down to, IIRC, 75% happy, 21% it's too loud and 4% want it louder. Lastly, although THX reference lists speaker based volume at 85-105dB and subwoofer, LFE content at a Lmax of 115dB, 95% of sound is in the <90dB range with >100dB being fractional (0.01%) when compared to the total of the movie sound track.
What all this means is, we're all being fed a bunch of hooie as to what's what with what as we strive for a standard that doesn't exist is real life and my compromise, so as to win the much coveted WAF, is to learn about and strive to achieve real world standards to I don't have to worry about any "Dear Ann Landers" letters being written to the local paper's editor on what a thoughtless sonic cad her husband is.
Boo-hoo for me. Cinemas - do they pose a risk to hearing?
"ResultsA summary of the results is shown in
. For the duration of the film the L Aeq range was 73 to 79 dB(A), which dropped to 67 to 74 dB(A) for an equivalent 8-hour daily exposure. The maximum SPL (L Amax ) recorded for each film exceeded 90 dB(A) in every case. However, this is put into context when looking at the exceedance levels. No film exceeded 90 dB(A) for more than 5% of the time, which varied between 6 and 8 minutes. With the exception of The Siege, no film exceeded 90 dB(A) for more than 1% of the time, which was approximately 1 to 1.5 minutes. Furthermore, for all films except The Siege, sound levels exceeded 90 to 95 dB(A) for only 0.01% of the time i.e. less than 10 seconds. The Siege exceeded 90 dB(A) for about 90 seconds. All the films had a number of scenes with explosions and gunfire, however for a large proportion of the time the noise levels (L Aeq ) were below 75 dB(A). This is illustrated in [Figure - 1].
For one set of measurements made during Lethal Weapon 4 (not shown inas the noise levels were only recorded for part of the film) the L Aeq was 75 dB(A). However, the unweighted frequency measurements were much higher; the unweighted equivalent continuous level (L Leq ) was 82 dB and the unweighted maximum (L Lmax ) was 101 dB. The latter value is much closer to the decibel levels reported in the media."
I'm sure everybody can find "EXCEPTIONS" to the above but I'm not looking to exceptions in which to base our compromise on.
