calibration of insert earphones
I am researching the equipment necessary to properly measure the level
of signals reproduced through insert earphones.
I suspect the best way is to use one of these babies:
Can anyone please give me a rough estimate of the cost of a B&K
Are there cheaper ways to measure earphone levels that don't contemplate
buying equipment delivered with a mahogany case (e.g., building a
home-made coupler for the level meter)?!? For my applications a
level-measurement error of, say, ± 3 dB might be acceptable.
