Imprimir páginaExcessive sound pressure from earphones and headphones can cause hearing loss. Adjustment of the
equalizer to maximum increases the earphones and headphones output voltage and therefore the sound
pressure level.
Excessive use of headphones or earphones for a long period of time at high volume can be dangerous if the
output of the headphones or earphone connectors do not comply with specifications of EN 50332-2. The
headphone output connector of your computer complies with EN 50332-2 Sub clause 7. This specification
limits the computer's maximum wide band true RMS output voltage to 150 mV. To help protect against hearing
loss, ensure that the headphones or earphones you use also comply with EN 50332-2 (Clause 7 limits) for a
wide band characteristic voltage of 75 mV. Using headphones that do not comply with EN 50332-2 can be
dangerous due to excessive sound pressure levels.
If your Lenovo computer came with headphones or earphones in the package, as a set, the combination of the
headphones or earphones and the computer already complies with the specifications of EN 50332-1. If different
headphones or earphones are used, ensure that they comply with EN 50332-1. (Clause 6.5 Limitation Values).
Using headphones that do not comply with EN 50332-1 can be dangerous due to excessive sound pressure
levels.
