How loud is loud, What DB is actually loud?


I like I should say love old school rock and hip/hop rap and funk all kinds of music. I found out my dads listening level is around 75DB which i find to be completley unsatisfying.

I was looking up Quad esl's and everyone says witha 85DB rating they wont go loud, but how loud is loud, How loud is rocking out?

Right now on my Radio Shack meter at my chair, 50dB average "C" rated. Listening to Teleman Oboe concertos. Sound is wonderful, and my neighbors don't get bothered in the early A.M.
So I would say 50dB is the bottom end of real listening, any lower and it just gets to be background noise (my frig is pretty noisey... 30/35dB is a guess.
Anyway I listen up to the mid 70dB range, with peaks up to 82dB, and this is all quiet in apartment/not disturbe the other little old ladies (I am one of them now) next door.
So for the average old fart 80dB is loud.
Now when "I" was young, I could crank the stereo up too. I did not have a ratshack meter then, but would guess 90 to 95dB was the tops.
So 100dB+ would probably ALWAYS get the cops called.
in the 90s would if it was later in the evening, and the 80dB range in the early AM is cop /ticket territory.
For "Little old lady next door" listening, that lowers the level a LOT, thus max 85dB midday, 77dB evening, and NO dB after 11PM to about 7AM. The silence here in my 'over 55" apts is wonderful at night. (compared to the last place, with gunshots, hallway fights, arguing by drunken fools at 3AM etc.. the folks above coming home at 2Am and cranking up the stereo. a cheap boombox, bye the way. the place had gradually gone to Hell over the 17 years I lived there..) Now I can hear the mile away trains. (And I am only about a mile from my old place.)
This is my opinion.
Anything over high 80dB is gonna ruin your ears anyway.
AND consistent low level listening allows your ears to become accustomed to low level listening, and it then becomes as enjoyable, or even MORE enjoyable than listening at high volumes. (one also needs equipment that SOUNDS good at low volumes..)
85db at 1 watt at 1 meter 1 meter is far inside a car...
88db at 2 watts
91db at 4 watts
94db at 8 watts
97db at 16 watts
100db at 32 watts
103db at 64 watts
106db at 128 watts
109db at 256 watts and so on.
Imagine what it takes to get to 170db if you keep doubling your power to gain a measly 3db? You need to gain about 10db to double the perceived volume. Even with 102db speakers (which are rare), it takes more wattage than any amp I've seen to get 170db. I imagine that it sounds pretty crummy and distorted at those levels.
Low listening levels beget lower listening habits? Don't let my missus hear that! My life is hell already! It already feels like I listen to music rather like someone who is sitting next to a passenger on the tube who is using earphones!
180dB is instant distruction of hearing in humans.
The loudest car stereo (in a contest) measured at 185dB.
Some say 194dB is the loudest 'sound', and higher is a shockwave, and is not a sound at that point, (like an atomic bomb or big explosion, the shockwave can be seen moving away)
150dB for a short time will give permanent damage to human hearing.
Blue whales can whistle at 188dB. I guess underwater is different than in air. And i would NOT want to be right next to a Blue whale singing.
Then some claim to have produced louder sounds. Nasa claims 214dB. (but that may be a calculation based on some other measurement?)
Then various volcanoes have been heard exploding thousands of miles away...
Football stadiums with fans yelling: loudest 127dB.
Jets taking off 140dB or so...
European standards in the workplace are:
85dB employers must offer ear protection. at 90dB the employee MUST wear earplugs, AND the employer has to try to reduce noise levels.
In the USA those levels are 5dB higher for the rules to apply
75/85dB chamber music group in small venue
100dB is a chain saw or pnumatic drill.
110 dance club'
120 rock concert, thunderclap, (though a rock concert can reach 150dB peak)
130 jet takeoff, gunshot
120/137 Symphonic music peak (IN the orchestra, probably right next to the trombones and trumpets which by themselves can reach 120+dB)
So I hope this helps.
Niacin: you should try a good headphones setup. Then for when you want LOUD, you can use the phones.
I use headphones at night if I want to hear Rock..
And your wife will(almost certainly) have better hearing than you anyway.. it is a fact women have better hearing than men by a big margin, on average.
