There are many questions for headphone users:

- Will this headphone output be able to drive my cans?
- Are the headphones (or even my ears) in danger to be damaged?
- How much power is drawn from the headphone output at a certain signal level
- Why is there such a big difference in sound pressure level when I use different headphones?

All these questions can be answered by using the calculator below.

How to use the calculator:


Most people can hardly imagine the resulting sound pressure level of their headphone from just any given voltage level. Arranging an equation with effectivity and impedance of the headphone in question as well as the voltage level are not an easy task for mental arithmetic...

Simply fill in the specific data of your headphone and the voltage level you are planning to apply. You will get the resulting sound pressure level as well as power and current
drawn from the headphone amplifier's output.

Of course this calculator is valid for all kinds of dynamic headphones and for all headphone outputs, not only the Black Cube Linear.
