because of the makeshift way to test the listening volume on your headphones (cutting out a piece of cardboard and all that), i knew i wasnt gonna get a very accurate measurement, but still, this is going to far:
yea, i got one of those cheap 40$ spl meters and its terrible. not even worth the money. according to the meter i got, i listen to music at 110 db, which is roughly the same volume as a chainsaw... it also measured my dads voice at 75 db, and he wasnt talking loudly at all.
so i thought, ok, this is a cheapy meter, cant expect it to be that good, ill just try and be sensible about the volumes i listen to, but at least i can volume match my gear to see the differences between them. so i turn on sinegen in order to produce a single note without volume veriations and the meter just goes about measuring different levels with like, 15db differences.
i tried none the less to quickly estimate an average and try to volume match my e11 and my cmoy but i just couldnt do it. i tried several times and the volumes are always noticeably different.
if your getting an spl meter, get a good one. and if you still want to try out a cheap one, stay away from this one:
