Headphone sound pressure level?
We have a set of Sennheiser HD 280 pro headphones with a "sound
pressure level" of 102 dB "as per IEC 268-7". Since it also states a
sound pressure level of 113dB/1V rms, we are unsure exactly what the
maximum output level of these headphones actually is. The impedance is
64ohm. Would anyone know how to calculate this, or does anyone have
access to the full international standard for headphones (e.g., IEC
60268-7), a preview of which can be found at the link below?
