| Headphone frequency response
The frequency response specifies the highest and lowest frequencies reproduced by the acoustic transducer of the headphones. |
|
5 - 30.000 Hz |
| Nominal sound pressure level
The (nominal) sound pressure level is the pressure in pascals (Pa) with which the air and the eardrum are caused to vibrate, better known as the volume. The sound pressure level is therefore a measure of the volume of a set of headphones under standardized conditions. However, it says nothing about whether the distortion is low and the sound is good at such a high volume. |
