Abstract: An adaptive level estimator for providing a level estimate of an electric input signal representing sound is provided. The adaptive level estimator comprises a first level estimator that provides a first level estimate of the electric input signal in a first number K1 of frequency bands; a second level estimator that provides attack/release time constants associated with a second level estimate of the electric input signal in a second number K2 of frequency bands, wherein K2 is smaller than K1; and a level control unit that provides a resulting level estimate based on said first level estimates and said attack/release time constants associated with said second level estimates. The level estimator may be used in devices or applications that benefit from a dynamic adaptation of an input signal level to a listener's dynamic range of sound level perception, or to any other specific dynamic range deviating from that of the environment sound.

Abstract: An adaptive level estimator for providing a level estimate of an electric input signal representing sound is provided. The adaptive level estimator comprises a first level estimator configured to provide a first level estimate of the electric input signal in a first number K1 of frequency bands; a second level estimator configured to provide a second level estimate of the electric input signal and/or associated attack/release time constants in a second number K2 of frequency bands, wherein K2 is smaller than K1; and a level control unit receiving said first and second level estimates and configured to provide said resulting level estimate based on said first and said second level estimates and/or said associated attack/release time constants. The invention may e.g. be used in devices or applications that benefit from a dynamic adaptation of an input signal level to a listener's (possibly limited) dynamic range of sound level perception, or to any other specific dynamic range deviating from that of the environment sound.

Abstract: Disclosed herein are embodiments of a hearing aid having a first processing path and a second processing path. The different processing paths can have different latencies, allowing for different processing actions to take place. Further, the hearing aid includes a physical vent for providing fluid communication between sides of the in-ear component of the hearing aid.
