Title: 89dB headphone level
Post by: robertisonline on June 11, 2016, 09:59:39 am
Does anybody know how I can measure sound pressure with headphones? I use 89dB as a reference level using monitors but have no idea how this can be done with headphones.

Thanks,

Robert

the only way to properly do it to reference is to use a dummy head

a reasonable DIY head can be made by sticking the mic into the headphone and making a seal as best as possible.  IEM's are very difficult to work with

you can also measure the amp voltage and use the impedance/sensitivity measurements, assuming they are close to correct you will get an answer of some kind

Awesome, thank you very much.

Be careful, 89dB can be damaging to your hearing in less than 4 hours of exposure - especially if you're using headphones.
