Tools to measure in room response

works for me, others may have more or better ideas

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!

Primitive and tedious.

The optimal cost/precision/effort way is to use RoomEQ Wizard freeware with your laptop. You can get away with RS meter for this but a better mic is advised.

This will give you measurements of swept tones (without resorting to pen-and-paper or spreadsheet entries) and will also provide lots of other info.

The test CD and RadioShack SPL meter worked for me. Just take the measurements from your usual listening position.
