Equalizing IEM's

post #1 of 3
Thread Starter 

Hi!

 

Is there a better way to create an equalizer curve for an IEM and headphones?  I'm sure there is, but the only thing that I can find is a "dblogic SPL meter", but it seems like it is impossible to locate a dealer.  

 

Can you rig something up to measure frequency response with a Behringer ecm8000 mic?  The radio shack SPL meter?  Is there an easy to use software package that will give you a tone and then you can compare it to the next octave tone?  

 

Thanks!

For an IEM, what matters is the sound level when driving your sealed ear canal, so any open-air measurement is pretty useless for determining the response of an IEM. Unless you can get a probe mic into your canal along with the IEM sealing, there isn't much you can do.

Thanks for the reply.  This is what I was afraid of.

 

I have been searching around and it looks like there's been some work that's been done in this area.  Here's the post from here...

I don't know how well it would work, but I might read more up on this...

 

Thanks!
