I would like to measure SPL with a hand-held SPL meter, which has an SPL log and PC interface. My headphones are closed-back. It seems to me that I could get best results by placing the two cups of the headphones together around the microphone wand, so that the pickup would be close to where my ears would be, and in a closed-back configuration.
However, doing that with two transducers into a single mike would seemingly almost double the SPL that a single ear would hear. Is the right way to disconnect one side, then the other, and average the two samples? If I do that, however, the sound from one side is playing into a larger cavity than a single ear would encounter, perhaps under-estimating the SPL; or is that hairsplitting?
I thought that this kind of improvisation must be old hat for someone at ASR.... I am doing this mostly to make sure I preserve my hearing, not to do detailed research. (In other words, I don't plan to spring for Mini-DSP Ears, at least not yet.)
