at -20db, the average SPL should hover somewhere between 60 and 70db. 65db is the SPL of the average conversation. The peaks will be around 85db which is loud, but they aren't sustained so damage shouldn't be much of a threat at that level.
I've been playing with the dynamic EQ and voume since I got the unit but it's really hard to test as it definitely changes the overall volume like I have to lower the volume after enabling it so it makes it hard to tell what it's really doing. With a default offset I have to drop it like 10-15db.
well the entire goal of Dynamic EQ is to raise the volume of the surrounds (and now also Atmos speakers) so that lower volume effects can still be heard within the sound field. I would recommend to set it at +5db in the offset, that seems to boost them a little without going overboard. I had mine set at +10 and it was making the surround content much louder than the front soundstage. When I set it back down to +5 it sounded a lot more balanced, however there were still moments when it boosted the surrounds a bit too much. If your surrounds are a lot closer to you than your front soundstage, +0 or +5 offset is where you want to be.
The bigger issue is movies randomly mess with you. Big name studios with Atmos or whatever they'll still just have random scenes that are just super loud compared to everything else and you're constantly monkeying with the volume.
Yep. That's the dynamic range of the soundtrack. Its supposed to be a good thing....its more realistic in that whispers are quiet, conversations are normal volume and explosions are loud. In real life, explosions are VERY loud....I have hearing damage from the military, walking outside without hearing protection when they were firing off the big guns on a ship....BOOM...it literally stunned me, I had to sit down until my head cleared and my hearing returned. The dynamic range in a movie soundtrack is trying to convey this difference, only without the hearing damage. Remember that movie soundtracks have +20db peaks and if your system is calibrated, Reference will be 85db, so volume of -20 (60 absolute) will be 65db (conversation level) with peaks of up to 85db (which is the average level at reference +0)
If you are having trouble hearing the volume of the speakers at -30db, then my suggestion is to lower the ambient noise floor of your house or apartment. If you have fans going and the A/C running and the exhaust over your stove running and the bathroom fans running and the washing machine or dryer going all at the same time, your ambient noise floor is going to be above 40db. Any sounds below this point is going to get lost, and sounds within 10db to 15db probably won't sound very clear as the white noise from all the running equipment partially drowns them out. If you go through your place and turn off absolutely everything that makes noise, you will be shocked at how quiet it sounds and how much clearer your normal listening volume will now sound. Most people just turn the volume up and power through the ambient noise, and that does work, but if you don't want to turn it up....make your place quieter and that will help you immensely.
