Advice on Testing

208.138.185.71

Hello Everyone.

Before I ask my question, let me first say what a pleasure this site is. No ridiculous flaming, etc., just decent discussions about the hobby. I tip my hat and send my most grateful thank-yous to those who are responsible for developing and maintaining this site.

Now, to the question at hand: I am still fairly new to this hobby, and am still learning. I purchased some time ago a test cd and SPL meter. On the test cd, it has various tones on the frequency band from 20Hz to 20kHz, so that one can test the frequency response of their system. I would like to do this, but wish to make certain that I am employing the correct methodology.

The book with the cd indicates that the meter should be set at ear-level (I assume in the sweetest spot in the listening room). It also states that one should use the 1kHz band as a reference. So, can I assume that I should start by selecting a certain dB level for 1kHz. After doing so, I assume I would then leave the volume control at the same level to do the test, recording the dB level for each tone on the scale (e.g., 20Hz, 16Hz, . . . 12kHz, 16kHz, 20kHz). Is this procedure correct, or am I completely off base? Am I neglecting any procedures?

I also assume I am hoping to find that the dB level stays fairly constant with each tone on the scale. Is this also correct, or should I be looking for something else, or additional?

I would appreciate any help or advice that anyone could provide. Thanks in advance.

Tom
