I want to gather some suppressor data but I don't want to drop major coin on a piece of gear that I will only use once or twice. Beggars can't be choosers, but I am hoping for something digital which can measure the extremely high peak sound pressure levels generated by short duration impulse events.
I would like to borrow it for about a week, but I would be open to renting as well. I know some outfits rent this gear, but I figured I'd try here first.

What type of test do you want to do? You may want to take a look at www.silencerresearch.com. There's a lot of data there. Also, someone there might also have the equipment you need.

..and those will be worthless for gunshot noise measurement, suppressed or not.Originally Posted by lindertw
If you are going to rent a meter for example, only look at;
- B&K 2209
- Larson-Davis 800-B

If I was going to actually drop the money to rent one, I figured I would get a Larson Davis SoundTrack LxT...

The two meters I mentioned above, when used with the correct microphones etc., are pretty much the two industry standards for sound suppressor companies.
The SoundTrack LxT does not appear to have a high enough peak level for unsuppressed noise for example.

I'll have to take your word for it, as I have no practical experience in these matters. The brief research I did via Google indicated that several individuals and organization felt that the SoundTrack LxT was ideal for recording gunfire.
This may wind up being a flight of fancy, but I would like to gather some reasonably accurate data if I can.

You might want to contact John Titsworth for good info, he does independent sound suppressor testing at www.silencerresearch.com
Also, Gemtech publishes a sound measurement booklet that costs only a few dollars.

FWIW, unless you are using sub-sonic rounds you will probably not get very relevant supressor data because the sound meter will pick up the round's sonic crack each time.
Ask me how I know?
