Hi Kchiu,
The standard tools, like the SPl meter from radio shack are fine.
A better way IMHO is to get yourself an iPhone and buy the app for SPL meter. You can also buy a Real Time Analyzer application which will tell you frequency response from 20-20K.
Now, this method is probably 10% less accurate than above average measuring equipment, but it will put you squarely in the ball park, and it is on your phone!!!!!!
I have an Audio Control RTA which I use to measure room response for clients when needed, and I have a multitude of SPL meters, but I use my iPhone 10x more because it is SO easy.
Most of the time when taking these measurements a 10% deviation from exact is not a big deal anyway as long as you use the same device to gather all your data.
good luck!
