I'm interested in figuring out the volumes I set my headphones out as to not damage my hearing. I bought a Scosche SPL1000 sound level meter, and I'm not having any luck with it. I can set the headphones to levels far exceeding what I would listen to, put one end of the meter in one cup, and the end with the sensor in the other, and it will still only read in the mid-60s. I also tried it with my (crappy) computer speakers, playing a song while setting the volume fairly high (and IMO, loud), and the meter read about 32.6 decibels... the same levels it reports when I'm not playing anything at all. If I set the volume all the way up, it'll go as high as 70. I don't need a fancy one, just something with ballpark accuracy.
