Abstract: The hearing device to be worn by a user of the hearing device comprises an input transducer for transducing incoming acoustical sound into audio signals; a signal processor for processing audio signals; an output transducer for transducing audio signals into outgoing acoustical sound. Said signal processor is designed such that there exists an input SPL range of at least a portion of said incoming acoustical sound, in which an increase in input SPL of said at least one portion of said incoming acoustical sound results in a decrease in output SPL of at least a portion of said outgoing acoustical sound, wherein SPL stands for sound pressure level. Through this, at high input SPL the hearing device's power consumption can be reduced by making use of direct sound, which propagate as sound waves from outside the user's ear canal to the user's ear drum.
