SafeSound
With the earphones, SafeSound allows you to listen to music in a safe way.
When you listen to music through the earphones, the sound pressure on your ears is estimated¹ based on the electrical characteristics of the player and earphones. Then, the estimate is compared against the reference levels² of sound pressure. As a result, icons of different colors can be displayed to indicate status of sound pressure and the levels of risks to hearing damage.
Level of sound | Maximum duration |
pressure |
|
more than 90 | 30 minutes a day |
decibels |
|
85 to 90 decibels | 2 hours a day |
80 to 85 decibels | 5 hours a day |
safe | more than 5 hours |
| a day |
Tip
¹The methodology is based on European norm (50332- 1/2).
²The reference levels come from the minimum requirement for health and safety that the European directive 2003/10/EC provides for the noises exposed to individuals.
