Author Topic: Sound Level Meter Recommendations? Joe Redifer You need a beating today Posts: 12859 From: Denver, Colorado Registered: May 99 posted 03-13-2005 04:27 AM                        I have been using my analog Radio Shack meter for many years. But it seems longevity was not part of the original design. Sometimes it works, most of the time it does not. Even with a fresh battery the needle will occasionally stick, not work at all, not respond to any changes in the settings (weighting, range, etc) and need to be whacked to wake up. Whenever I set it to BATTERY it never hesitates to respond, however. This meter is supposedly fairly accurate and people do not like the digital version of this meter, as I've heard bad things about it. Does anyone have any recommendations on a comparably priced unit like this? Or any tips on how to get this thing working correctly again? I have a friend who has the same meter and his has the same symptoms as well.  |  IP: Logged Phil Hill I love my cootie bug Posts: 7595 From: Hollywood, CA USA Registered: Mar 2000 posted 03-13-2005 04:37 AM                  While I have no suggestion for a replacement, I must say that mine still works great. It is a great SPL meter for a quick check. It really is too bad that RS decided to discontinue that analog meter and make that POS digital version. Which I think is no longer available as well.  |  IP: Logged Michael Schaffer "Where is the Boardwalk Hotel?"

Go to http://www.conrad.com/, click on the Union Jack (you can also click on the German, Hungarian, Russian, or any other flag you like, but I have a feeling the British flag will work best for you) and type "sound level meter" in "quick product search".  |  IP: Logged Scott Norwood Film God Posts: 8146 From: Boston, MA.

Just get a busload of old people from the local nursing home and a busload of kids from the local high school to come to your theatre. Offer them a free movie. Before the show, play pink noise. When the old people start screaming "it's too loud, you're hurting my ears!" then the SPL is about 65 dB. When the kids stop telling you to "turn it up!" then the SPL is about 105 dB. Set the levels to the intermediate position between the two extremes, and you will have a perfect 85 dB.  |  IP: Logged Richard May Phenomenal Film Handler Posts: 1057 From: Floral Park, NY USA Registered: Aug 2004 posted 03-13-2005 08:42 AM                     Radio Sack still has the digital version. I have the analog one though. It's worked fine for 10 years. I did'nt know they stopped making it. Too bad.  |  IP: Logged Scott Manley Film Handler Posts: 59 From: Austin, TX USA Registered: May 2001 posted 03-13-2005 08:50 AM                     I've noticed mine started to need a little nudge to get working every now and then and I think I bought it at least 10 yrs ago.......dang these things don't last long huh? I just found this one on the Rat Shack web site Catalog #: 33-4050  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 03-13-2005 09:08 AM                     Joe, I have an old Rat Shack meter you can have if you want it just e-mail me your address and I'll send it to you, or go visit Gord and have him take you to TS&S...... I use a trusty Bruel & Kjaer 2205 meter that I bought on a trip up to see Gord. 80 bucks at Toronto Science And Surplus. Gord bought one too! Built like a tank and I get it calibrated once a year.

Scott, that's too funny! Btw, my Rat Shack analog SPL meter still works, too. Got it in 1980.  |  IP: Logged Rick Long Jr Expert Film Handler Posts: 211 From: Toronto, Canada Registered: Jul 2000 posted 03-13-2005 10:48 AM                     Like most people, I've used the original RadioScrap analog spl meter with good results overall. I take the opportunity to calibrate it whenever I happen to be working with someone who has the proper gear, or one that has been calibrated more recently than mine. When it got lost recently, I found myself having to buy one on the road, and ended up getting the then model Scott mentioned a few posts up. It was either this one or the digital model, which I have used, and don't like at all. This new analog one seems to work well, and has all the same functions, however the mic element is a bit smaller, which makes me wonder about its accuracy at lower frequencies. (Not that you can really use an spl to accurately set a sub anyway.) When I got back, I was able to do some not very scientific comparisons with another older analog unit, and it seemed to be fairly accurate overall. I still prefer the older one though.  |  IP: Logged Paul Mayer Oh get out of it Melvin, before it pulls you under! Posts: 3836 From: Albuquerque, NM Registered: Feb 2000 posted 03-13-2005 11:31 AM                        Wow! $80 (I assume Canadian) for a B&K! I need to see if I can make a score like that. If their meters are anything like their instrumentation mics, they'll be jewels of perfection. I too have the older RatShack analog meter. Still works just fine, which it should, given how little it gets used. For those having intermittent problems with the meter, could it be a case of some solder joints going bad? Might be able to fix things by reheating some connections.

USA Registered: Sep 1999 posted 03-13-2005 06:53 PM                     Radio Shack does stock repair parts in Fort Worth for many of their products. I suggest getting the service manual and looking up the part number for the meter itself (if you're having needle sticking problems) and just order a replacement meter. MCM Electronics (www.mcminone.com) sells an analog sound level meter as their # 72-6604 (around $80).  |  IP: Logged Rick Long Jr Expert Film Handler Posts: 211 From: Toronto, Canada Registered: Jul 2000 posted 03-13-2005 08:23 PM                     You could also try going over the solder joints for the switches. Could also be a hairline crack in the PC board. This happened to my old one. I was able to fix it. (Before I lost it)  |  IP: Logged
