I dunno, I'd rather see a numerically integrated or captured result than "get a sense" of it. Not me. The number you see is some type of interpolated average, it's never what's really going on. How do they come up with the avearage? That's the problem, you don't know. And you are guaranteed just by the way they work that transients and spikes are gonna be shown wrong. It's the same reason that digital voltmeters are useless on signals that bounce around a lot. You must have analog to see what's happening. -Tommy Unless you have a specification for the dynamic response of a meter needle, and a complementary knowledge of the transient characteristics of the sound, then you are absolutely no better off with an analogue meter than a digital one. They both have a dynamic response that is hidden from you. Of course with a purely digital meter you are far better positioned to have something you can actually characterise in some meaningful way. Spikes will be shown "wrong" (whatever that means) on both types of meter. Choose which you like on the basis of convenience. If you are characterising a room with pink noise or pure tones in multiple positions, then the digital meter is going to be far easier to use - just write down the numbers. If you are monitoring sound levels in a dynamic environment, then go for the analogue. d _____________________________ http://www.pearce.uk.com |

I don't why it would be far easier. Analog meters have numbers, too. Just write them down as well. If you are monitoring sound levels in a dynamic environment, then go for the analogue. Well, that's almost always what I'm using mine for, so maybe that's why I prefer it. I still think the analogy of the analog/digital voltmeters is relevant. If you have even a moderately varying signal coming in, a digital voltmeter is totally useless. If it's reasonably stable, analog or digital will work just fine. - Tommy |

I've got one of the digital RS meters and it has an analog
scale bar graph on the bottom of the LCD as well as digits just like my fluke DVM. Works well for me... -- AudioGaff "Mike Rivers" wrote in message news:znr1058013574k@trad... . IMHO, the digital numbers change too fast to give you a good sense of what's really happening. That's too much attention to devote to a meter when you should be mixing, though it might be more useful when checking frequency response of a room using warble tones or 1/3- or octave-band pink noise. |

It just simply blows me away that some people can't make change without a calculator or cash register. What happened to adding, subtraction and multiplication tables? Whatever :( Wayne |

Obviously the volume levels have been going up at all kinds of entertainment
venues. A couple weeks ago we went to see "Winged Migration". This is a feature length nature documentary on bird migrations. Very beautiful & highly recommended. But it was ****ing deafening. I literally had to stuff kleenex in my ears to be able to tolerate sitting in the theater. This is absolutely insanely stupid, especially given that the audience consisted of about 10 other middle aged adults. What ever happened to OSHA? Oh, right... They're out working hard to protect the rights of industry to provide dangerous work environments for American labor. Scott Fraser |

Years back, we played a club that had a system that shut off stage power if
the sound level exceeded some arbitrary limit. While a good idea in theory, in practice it sucked. A more sensible system is that used at a performing arts center in Sun City, Arizona that basically has an audience of retirees. The house sound guy sits at the console with the guest engineer. He has an SPL meter in one hand & his other hand on the output gain of a DBX160 limiter on the system. Go over 95db & he cranks you down. When I mixed a Mel Torme/big band tour there the applause was consistently 5 to 10db louder than my mix. The house management was very pleased. Scott Fraser |

I find the digital readout impossible to use unless you have a constant signal. Otherwise the display is constantly bouncing around. Even worse than a digital speedometer. On musical signals it seems utterly worthless but give it a try and see if you don't agree. They'll let you play with them in the store. --scott -- "C'est un Nagra.

( 84 dBa is the threshold for damaging noise that I was trained for when I was in the navy running the hearing conservation program on my ship. ) Apropos of this discussion, I ran across this web page that showed the worlds largest VU meter, which I though folks here would appreciate. It was, of course, at MIT. --Dale http://hacks.mit.edu/Hacks/by_year/1...bldg_vu_meter/ |

James Boyk wrote: Right; and the one to get is the "analog-display." Other than it being the one on sale, why is that? The digital meter has nice features like peak or average measurement. I find those types of options nice when reviewing information statically, i.e., after the fact of capture. I don't like watching a numerical display never come to rest when reading data in realtime, compared to watching a meter needle wave around. In the realtime case, I need a good ballpark, and I'll do the "averaging" myself. -- hank alrich * secret mountain audio recording * music production * sound reinforcement "If laughter is the best medicine let's take a double dose" |

Did more than a few shows with Uncle Walt. Have you seen Champ's son play the fiddle? ...Got a great little group called the "South Austin Jug Band". Yeah, Warren is damn good and a great guy, too. Met him and heard the SAJB at Threadgill's last year, and saw him again this year at Antone's big Monday night when Clifford finally got off of federal probabtion and could actually go to his own joint. Was quite a night. Warren went to Berklee last year and this summer has been in Austin with some young bluegrass pals of his from school, tearing it up and drawing sizeable crowds. (This last trip to Austin got the pressingly urgent biz stuff out of the way, so I'm again aiming to see you, Harvey and some other TX outlanders next trip(s) later this year. Be there in December for sure.) -- hank alrich * secret mountain audio recording * music production * sound reinforcement "If laughter is the best medicine let's take a double dose" |

You don't get to design it, you take what they give you. IMHO, the digital numbers change too fast to give you a good sense of what's really happening.

Have the best of both worlds - get both. It's still less than $75, even when not on sale. -- I'm really Mike Rivers - ) I tested them both on some music at the Shack on Saturday. Definitely picked up the analogue meter to add to the kit. I used it to check my levels in church on Sunday. The main source of energy behind the plexiglass was near the rhythm section - more monitors and live amps - Sound there was around 100dB on the average. The vocalist's hot spots showed surges of 102 to 104 from 6 feet back. The FOH, measured from 25 feet in front of each of the mains, averaged about 82 to 86 dB. The FOH from the mix position was in the low 70's... all "A" weighted. Interesting. -- David Morgan (MAMS) http://www.m-a-m-s.com http://www.artisan-recordingstudio.com |

We have one of those, but they're just ridiculous. If you go to a regular RS, you'll probably score. At least on the meters. I wouldn't be surprised if the splicing stuff gets torpedoed everywhere sometime soon. The "Radio Shack Dealer" here is actually a tire store. They don't carry anything electronic and can order even less. You're more likely to find electronic stuff at a 7-11 than these places. - Tommy |

And I think I recall an accident with lasers at a light show. But of course these things shouldn't happen. And when they do, they no doubt give rise to liability claims and lawsuits because people are outraged that they or their near & dear were injured. But why---WHY?---don't we regard our sense of hearing the same way? Because due to the way we work, we don't notice it properly until it's way too late, unless we are well trained in advance. Trying to talk to folks technically doesn't often seem to work, IME. So I've been coming up with different ways to try to get the point across, and the one that's gettign results so far is to compare what happens to our hearing sensitivity to the development of callouses on our hands. Callouses somewhat reduce tactile sensitivity and most folks have done enough manual labor somewhere along their path to be able to relate to that. So I tell them to realize that the ear develops callouses _almost immediately_ when confronted with "abrasive" sound, i.e., too loud, and that the resulting reduction of sensitivity prevents them from realizing just how loud the sound really is. More laypeople seem to get that concept than any other I've been able to think up. -- hank alrich * secret mountain audio recording * music production * sound reinforcement "If laughter is the best medicine let's take a double dose" |

Radio Shack has the analog-meter SPL meter on sale now. For $25, it should be your "next condenser microphone" (and it DOES have an output jack). So I called the RS dealer in Quincy CA, my localist RS, and they can't find that meter anywhere in their reference material. I want one. How'd you find out about it? An out of the blue question for you Hank, since you live near Quincy: I was down there a few weekends ago for High Sierra... You have any info on the car accident on 70 in the Feather River canyon? As we were leaving Quincy, about 7pm on sunday evening (July 6) we were passed by several ambulances. Turned out a car had gone off hte road, fell what looked like 50+ feet to the river and was in the middle of the river on its roof, partially submerged. Several ambulances, a fire truck, and a chopper were there. I'm just wondering what the hell happened... --- Aaron Borgman HE Design Engineer RA2-4-D15 phone: 971-214-8380 Disclaimer: All above opinions are mine... not Intel's |

great idea.... i would add that callouses on our hands go away when we don't need them any more; but the metaphorical ones on our ears are forever. Yep, and I tell them that, too.
