What level do you listen to your movies at? Reference level is defined to be an average level of 85 dB, with 105 dB peaks; 115 dB Peaks on your sub.

This assumes minimal distortion is occuring.

I made a mistake on the poll. Choice #2 should be 'my system does not support it'

-5 to -10dB of reference for my room, however, I will demonstrate at times the "real" audio of an action Blu-ray flick!

Normally 0dB is reference level, so -13dB is 13 dB below reference, it could be that your particular type of receiver is deviant there, though I doubt it.

I normally listen between -14 and -8, depends on the movie and how it sounds to me. reference in my room is just too darn loud and not very enjoyable lol.

Reference level is way too loud in my theater on almost every disc except Phantom of the Opera on HD DVD, which I do listen to at reference level.

Mike, I think your question and poll is misleading. To my knowledge, all automatic setup systems such as Audyssey, MCACC, and YPAO use 75 db as reference level for home theater use.

For setup, and in doing so true reference level on your dial is then 0db.

I listen around -10db typically for movies but will go up to reference for NIN or other concert Blu-Rays.

It's to keep the test tones from being too loud. On material playback, reference will be 85db.

YPAO sets mine up for 85 dB near as I can tell. I thought differently, until I realized I had compression turned on.

As Easy says, test tones seem to be 10 dB lower.

Can you test your setup to see how it's calibrated?

I guess what we are all trying to say is 75db or 85db is used to calibrate reference level because the level of the calibration tones is such that you don't go deaf trying to do the calibration. After calibration when you have the volume at 0db you will get max (reference) volume of 105db.

Audyssey on my Onkyo 706 uses 75db for calibration.

that's not correct, the test tones are -30dbFS to keep them from scaring the crap out of you, so if you measure the internal pink noise tones with the volume at "0" you will get 75dB, but that isn't the same as content (where Full Scale = 105dB max per channel). what the AVR uses as the calibrated level with test tones isn't the same thing, but in my experience almost any manufacturer uses -30dbFS tones (so it would be calibrated at 75dB = "0" on the volume dial).

this is a quote from Chris in the Audyssey thread:

Quote:


Reference level is defined as the level used in film mixing. This is a standard used in all film mixing.

Reference is defined as 85 dB SPL (C-weighted, slow) at the listening position using –20 dBFS (FS= full scale) band limited pink noise (between 500-2000 Hz). Every studio and movie theater is calibrated this way and this provides the capability for 85 + 20 = 105 dB max.

This 85 dB noise is a little too scary for home users, so manufacturers provide a test signal that is 10 dB lower (–30 dBFS) and so home theaters are calibrated to measure 75 dB SPL for that noise. The result is the same when the master volume is set to 0 (i.e. 30 dB above 75 dB = 105 dB max).

Not that I think the poll is reliable in any way, but it seems a fair amount of people think they can hit reference levels.

That surprises me a bit.

Not only does your amp have to be up to the task, but so do your speakers and sub. The sub, in particular, has to be able to hit 115 dB peak with minimal distortion which I would think is uncommon, or even rare.

When I am casually watching a movie, I usually listen at -20 to -25.

When I am serious about watching a move, I listen at -10 to -15.

I always use Dynamic EQ, and I set my subs ~10dBs hot. Therefore, at -10 MV, my LFE channel is around 4dBs hotter than reference. My mains and center (all Def Techs) can handle reference just fine. It is just too loud for my tastes. -10 to -15 MV is just right for me (and my tastes).

Never argue with an idiot; they drag you down to their level and beat you with experience.

Audyssey on my Onkyo 706 uses 75db for calibration.

As Primetimeguy says, Audyssey uses 75 db for calibration on the Onkyo 706 (which I also have).

Here is what Audyssey says about home theater reference level:

http://www.avsforum.com/avs-vb/showp...ostcount=13493

Edit: Just read Batpigs post. It appears maybe I am confusing "reference level" with "calibration level." Does that make sense considering the quote that Batpig provided and the similar one that I included?

For the record, I usually listen at -18 db to -15 db. Is that referenced to 75 db at 0 on the volume knob or 85 db.

Reference level refers in this case refers to SPL level. If your receiver calibrates to reference level, 0 dB would be 105 dB peak level, 115 dB LFE channel.

Yep.

I might add that if you have all of your non-LFE channels set to "small", then your LFE can have peaks of around ~122dB (because of the re-directed bass). But this is a bit OT.

that is exactly what I was trying to say.

"reference level" is specifically defined for movies; each channel can have content up to 105dB. That is the max value, called "Full Scale".

that is why the pink noise is referred to as "-30dBFS" to mean that it is offset precisely 30dB below the 105dB theoretical max. With a -30dbFS tone, you would calibrate to 75dB. If you had a test disc with -20dBFS tones, you would calibrate to 85dB.

either way, it doesn't change the definition of "reference level."

(and of course as mentioned above the LFE channel has an extra 10dB of room so it has up to 115dB max. however this doesn't affect your CALIBRATION because what you are calibrating is the subwoofer volume, not the LFE channel)

since we are struggling for precision here, the redirected bass is not part of the LFE. It is more accurate to say that (because of redirected bass combined with LFE) the subwoofer channel can have peaks of around ~122dB.

I think it IS on topic. Because I think many people think they can do reference level, but their subs may not be able to keep up.

agreed, this takes me to your comment above:

I am not sure people really understand how loud that is, especially demands placed on the sub channels. I have no illusions that my system can hit reference level, and that's OK because I don't need it to (I live in a townhouse!).

In the Audyssey thread you often get people wondering why they are bottoming out on their single 12" subwoofer when listening at -10 or -15 during those really crazy LFE moments in action flicks like Transformers or Iron Man.... they are like, "gee I though this subwoofer was awesome, I paid $800 for it!" but I think the problem is they don't understand how much freaking "subwoofage" it takes to be hitting 105dB+ (when you combine the LFE peak with redirected bass) at the seating position.

Hey Michael, I agree with you about hitting reference cleanly. The LFE is 115 dB's by itself but if any bass management is involved the max it can hit is 121 dB's. Many people say it sounds too harsh at reference levels which tells me that their system can not handle it. I good idea would be to get the specs of their speakers(sensitivity and power handling) and then how far they sit away from their speakers plus amp power used.

To give an example my speakers are rated at 101 dB's at 1 meter with 1 watt. I also owned JTR triple 8's rated at 95 dB's and Klipsch THX ultra 2 speakers rated at 97 dB's. The JBL's were 10 dB's more sensitive then either the JTR's or Klipsch(using the same exact equipment). Anyway, my speakers are rated at 400 watts at 4 ohms. I run 750 watts at 4 ohms so plenty of power. My subs of course are capable with plenty of power as well. I had an SVS PB12/plus/2 that could only hit 110 dB's from the front location. If I sat near field(1 meter) I could muster 120 dB's from it but then it started to compress which kills the dynamics. I sit 4 meters away at the front row and 5 meters from the back row. People tell me all the time I could use a receiver because my speakers are very sensitive but I clipped a 160 watt per channel Mac amp at 4 ohms(rated). There is more to this than specs. We could figure out with specs how much power one needs for reference and then see if their speakers are even rated for that much power. People will say that more than one speaker is playing but the spec(reference) calls for each channel to play 105 dB's when called upon.

JBL 3622N: 101 db=1 watt
104 db=2 watts
107 db=4 watts
110 db=8 watts
113 db=16 watts
116 db=32 watts
119 db=64 watts
122 db=128 watts
125 db=254 watts
128 db=512 watts

I sit 4-5 meters away so every time you double the distance you lose 6 dB's. I lose 12 dB's at my front row which brings me to 98 dB's at 8 watts, not 110 dB's.

With seating distance: 98 db=8 watts
101 db=16 watts
104 db=32 watts
107 db=64 watts
So 50 watts should cover reference levels but that is without headroom and would probably work the amp too much. So 3 dB's of headroom will require a 100 watt amp. I still clipped a 160 watt amp during some peaks.

We could do the same thing for subs.

I run 8 subs which make my subs rated at 108 dB's at 1 meter at 1 watt but at my viewing distance it makes it 96 dB's at 1 watt.

Subs 96 db=1 watt
99 db=2 watts
102db=4 watts
105 db=8 watts
108 db=16 watts
111 db=32 watts
114 db=64 watts
117 db=128 watts
120 db=256 watts
123 db=512 watts
126 db=1042 watts
129 db=2084 watts

I run 1200 watts per sub.

Sorry about this post guys, I was bored doing paperwork. It can give you an idea though. I see many people posting that their 86 db sensitive speakers that play 250 watts(max) can hit reference easily with their receiver, it just does not add up.

AVR-Yamaha A830
amps-5 Adcom 555 in 850 watt monoblock mode
sub amp-Sanway FP14K
LCR-Dual stacked BFM DR-250's
Surrounds- Dual stacked BFM W10's
subs-12 SI 18's ported 6hz.

115db peaks, what I can't hear you because my hearing is now damaged.
