Testing Gun SPL's

(1/4) > >>

Eric Deweese:
Hello, Subject says it all.....I have a friend who is working on some tasty gun accessories to reduce recoil and Sound levels to the person firing the weapon. He asked me if I would help him do Preliminary testing to make sure he is indeed going in the right direction. So to my question, is there anybody who knows of a decently priced HIGH SPL meter that is portable? So far the only thing that I think is in range would be the Goldline SPL 162R.....and while he said we could work out a deal for that much $$ I was wondering if there were any other options out there that would help us get the prelim testing done before he drops serious cash on final testing analysis at a lab. Any input would be appreciated thanks!

Hi Eric,

You can start at .99 cents and go up from there.

   Hello,

   To successfully capture accurate data for your project, you'll need a type 1, meter. It'll need the ability to be field calibratable. (you'll need a precision calibrator)
  It'll need the ability to measure PPL or Peak Pressure Levels as a standard SPL meter will not be able to capture the data fast enough, and/or some meters will average the impulse due to overloading the input.

  You'll need a meter capable of "fast" impulse measurements of up to 180 dB.

  Anything else would be useless information if this a serious project.

  I'd recommend renting a Larson Davis 800 SPL or similar spec model.

I wonder if, as an alternative to dedicated hardware, there's software that can be installed on a laptop at a lower cost?

   Hello,

   Probably, but, being a smaller market than a standard SPL meter or Dosimeter, (read: specialty equipment) there would most likely only a small amount of companies offering such gear.   (look to the Japanese Manufacturers ...or Larson & Davis (supplier to the Military, NASA, and Airport Noise Monitoring) 

   Remember, that you'd still need a quality, calibrated microphone capable of high SPLs, and the signal conditioning box (preamp and power supply) and calibrator.
