Method and control arrangement for adapting a sound level of a sound emitting device to environmental sound levels

摘要

Method (400) and control arrangement (340), for adjusting a sound level of a sound emitting entity (320) of a vehicle (100). The method (400) comprises monitoring (401) environmental noise level; comparing (402) the monitored (401) environmental noise level with a noise threshold limit; and adjusting (405) the sound level of the sound emitting entity (320) based on the monitored (401) environmental noise level in relation to the noise threshold limit.
