Output cable for digital RadioShack SPL meter

[Rullknufs]

This might seem like a noobish question, but what cable should I use to connect the digital RS SPL meter to my computer's soundcard?

The output signal is mono analog. The older meters used an RCA phono connector, don't know what the new meters have.

That's how it looks like

The case looks just like my analog meter. The connector is a common standard RCA female phono jack.

So a cable like this one would work if I want to connect it to my computer?

An externally hosted image should be here but it was not working when we last tested it.

Yes.

I have one of the RS SPL meters, but am looking for a meter that will go lower. I would like to go down at least to 40dB SPL, and preferably 30dB SPL.

I am interested in mapping ambient noise levels and teh RS meter simply shows "LOW" when I try to take readings.

Has anyone tried this meter? If so please evaluate it.

Does anyoen have any suggestions?

TKS.

B&K's 2240 SPL meter measures down to 30 dB.
Type 2240 - Sound Level Meter - Type 2240 - Brüel & Kjær
I believe the much cheaper 2219 goes down to 35 dB.

It should be possible to obtain a sufficiently quiet microphone or capsule alone, and DIY the electronics.

Gimp: You would trust a $40 RS meter to be accurate? I checked mine against a B&K and only the median settings are OK. The upper ranges suffer from compressions in the mike, the lower ranges suffer from noise in the preamp. E

Thanks mickkymoose, How far off are the ends?

I've found an article on modifying the earlier analog version, but nothing on the digital version.

I'm primarily satisfying my curiosity with the SPL meter.

I'd like to know what the background noise level is in my den where the entertainment system is. How loud do I actually play the stereo, etc.
