That seems extremely soft. If the majority of the movie is at 70-80dB (which has nothing to do with the level of test tones) then you are listening at whisper levels (40dB). How did you calibrate your system?
I calibrated, using the internal test tones of my Proceed AVP, to 75dB at the 00 mark (THX-ref.). I routinely listen to the movies at volume levels in the range of THX-ref.+2dB to THX-ref.+6dB (with Dolby Digital software, that is). In my recent review on the Aerial package I purchased last year, which I posted in IV parts at the Audio Video Improvements forum, more details and specific examples are given.
Incidentally, if anyone is interested on having the whole Aerial review in one single WORD file, just e-mail me at: [email protected] .
No, the volume numbers are not db measurements. Setting to "reference" is less crucial than having all channels calibrated properly and putting out the same SPLs at any given volume, while using test tones.
But, when a system is calibrated to "reference", it's nice to have that commonality with other HT enthusiats. That way we all know what it means when someone says they "bottomed a sub at -5 while watching U571." Or when someone says "I listen to music at -10"....Others will have a sense of what that means.
If anyone is interested, here is a link to a thread which gets pretty involved, but is worthwhile reading.
OK, call me crazy, but I watch movies at reference level, which puts me in the minority already. When a sci-fi lovin' chick came over, I pumped it up to +7db, which had the effect of a whole lotta shakin goin' on. I think I clip at +8, so that was about as high as I could go and still stay clean.
I watch TV at -10 (good movies) to -20db (news, surfing) and listen to music at -20db.
I don't know how load reference is set at, but at +3db on music, it is friggin' loud. Anybody know what level Parasound sets their reference meter at?
DAMM!!!!...I guess I would be leaving your house with an ear ache or you like ZERO conversation during movie!!!...lol!! I have a Denon AVR 3200 and I like mine loud but for D/D movies I set mine to -10 and music to -20.
My Denon is 80WPC..how many watts is the 3802? My Cambridge Soundworks speakers are 89db so the Denon pushes them w/o issues.
I calibrated my TAG AV32R so that "00" is 75 db. I always set the movie volume, with the wife and kids in the room, at -5db on the TAG. That works for about 80 percent of the movies we watch. Sometimes I have to turn it down to -7.5 db or -10 db for particular movie (e.g., The Fast and the Furious). It surprises me that some listen at -20 db or lower. It would seem like you're missing all the fun.
A system properly calibrated with 85dB tones will be as loud as a system calibrated with 75dB tones.
1. You set the receiver or pre/pro to reference level (00, etc.)
2. The encoded tracks on the DVD can contain information from 0->105dB (sub up to 115dB).
3. Disc A happens to use 75dB tones which are loud enough for calibration. After adjusting each speaker level (so they measure 75dB) your system will play from 0->105dB (assuming the volume knob is still on 00).
4. The numbers on the volume knob don't always track with decibels +/- reference.
At reference, the loudest any information above 80Hz can be played is 105dB (this is during peaks). Here is a link with typical SPLs for various sounds. Here's OSHA's recommendations . Keep in mind that soundtracks do not go above 90dB except for very short peaks (explosion, etc.).
Don't forget one thing...when you calibrate to 75dbs, the disc you are suing to calabrate is actually recorded 30dbs lower, so when you've calibrated 00 at 75dbs, it is actually 105dbs...just thought i would confuse things more.
You cranked the volume up another 7 dB for a girlfriend visiting? Don't forget the 6 dB sex difference for preferred volume level. Females will tend to place the volume about 6 dB below males. That means you were probably mega-blasting her poor ears.
In our home system, the usual movie watching volume is 23 to 20 dB below reference.
