marcophile Posted June 16, 2005 Share Posted June 16, 2005 I do not own an SPL meter but was wondering what the decibel level might be approaching in my listening room. Listening Room: 20x24 Acoustical tile ceiling at 7'-6"...carpeted and furnished. Sharp corners and hard walls. Listening chair is centered...3 feet from back wall...along 24ft wall.(15-20 feet from LS) Speaker: La Scala 2004, toed in along 24 foot wall...placed in corners. Toed up with a 1" block under front edge Amp: Mcintosh 6500 Source: CD Player Music: Rock ( i.e. Flamin Groovies, Nick Lowe, Ramones) Amplifier output: steady output bouncing between 2 and 25 watts..although I'm sure the exact output is more if it was measured digitally Curious to know if SPL can be estimated..thanks Quote Link to comment Share on other sites More sharing options...
rplace Posted June 16, 2005 Share Posted June 16, 2005 Sorry, can't help you with the SPL but anyone listening to the Ramones on LaScalas can't be all bad. Get some Clash to go with em and crank it up. Rock on, Rich Quote Link to comment Share on other sites More sharing options...

rplace Posted June 16, 2005 Share Posted June 16, 2005 Cool tool! 127db that is loud right? Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted June 16, 2005 Share Posted June 16, 2005 psg, that calculator is pretty neat. Beginning with the LaScalas 104 db/w/meter, adding 3 db for every doubling in power up to 32 watts (1,2,4,8,16,32)for the peaks, subtracting 3 db for every 8 feet of distance from speakers, calculator comes up with 114 dB, which is PRETTY DARNED LOUD. I don't suggest listening at that volume for very long periods as hearing damage is sure to result. Michael Quote Link to comment Share on other sites More sharing options...
CaptnBob Posted June 16, 2005 Share Posted June 16, 2005 That calculator is pretty neat. It should be remembered that, depending on the room and other imponderables it could be MUCH louder. Also, I'm not sure about the ballistics of the Mac's meters, but your peaks could be much louder than they are registering. SPL meters are pretty cheap at Radio Shack. Much cheaper than a hearing aid, if you catch my drift ... Quote Link to comment Share on other sites More sharing options...

Parrot Posted June 16, 2005 Share Posted June 16, 2005 And once you get tinnitus, there ain't no goin' back. You've suffered irreparable damage. Quote Link to comment Share on other sites More sharing options...

Frzninvt Posted June 17, 2005 Share Posted June 17, 2005 130.5db not to bad I think, my car gets about as loud as that too! Not that I listen at those levels but I have tried it a time or too, it is amazing they can play at that level with no breakup or distortion.

marcophile Posted June 17, 2005 Author Share Posted June 17, 2005 Thanks PSG...a very helpful little chart. I can't take more than 3 or 4 songs at that volume...but I certainly listen at 105db for extended periods of time. I believe rock concerts hover around the 120 db level...wow!

psg Posted June 17, 2005 Share Posted June 17, 2005 Yeah, I do most of my listenning at 90 dB or so and there's some stuff that needs 105 dB to sound realistic. The difference between us and other people at 105 dB is that we set it and forget it and other people can't enjoy the music because they are affraid of damaging their speakers; no head-room left! If I've got 10 or 15 dB left, then the occassional louder passage doesn't worry me one bit! Sweet! This is specially true in HT. Loud passages in movies are unexpected. I can just enjoy the movie without running to the volume dial when it gets loud. Quote Link to comment Share on other sites More sharing options...
