摘要： Example embodiments disclosed herein relate to audio signal loudness control. A method for controlling loudness of an audio signal is disclosed. The method includes responsive to determining presence of a noise signal, deriving a target partial loudness adjustment based, at least in part, on at least one of a first factor related to the noise signal and a second factor related to the audio signal. The method further includes determining a target partial loudness of the audio signal based, at least in part, on the target partial loudness adjustment. Corresponding system, apparatus and computer program product are also disclosed.

摘要： The present invention concerns an audio amplifier circuit (1) designed to provide an output signal (Vout) to an audio transducer (2), said audio amplifier circuit (1) comprising an audio power amplifier (3) designed to receive an audio signal (Sin) at its input and designed to generate said output signal (Vout) at its output, a sensor (4) designed to detect an audible sound having at least one noise component, to generate a detected signal (Sdet) at its output. It further comprises a processing block (5) which is designed to receive said detected signal (Sdet) at its input and to generate an off signal (Soff) at its output, the latter being located at the input of said audio power amplifier (3), said processing block (5) processing said detected signal (Sdet) according to said input signal (Sin) to identify said noise component (Vn) of said detected signal (Sdet) to generate a reference signal (Smod'), said processing block (5) generating said off signal (Soft) at its output when the value of said input signal (Sin) is lower than the value of said reference signal (Smod').

摘要： Vorgeschlagen werden ein Verfahren zur automatischen Steuerung einer Einrichtung (7, 8, 9, 10), welche Geräusche (71) im Innenraum (11) eines Fahrzeugs (1) erzeugt, wobei eine Gesprächssituation im Fahrzeuginnenraum (11) erkannt wird und wobei die Einrichtung (7, 8, 9, 10) zur Reduzierung der von ihr erzeugten Geräusche (71) im Fahrzeuginnenraum (11) gesteuert wird, welches sich dadurch auszeichnet, dass zur Erkennung des Vorliegens oder Bevorstehens einer Gesprächssituation Aktivitäten eines Fahrzeuginsassen (45, 48) erfasst und ausgewertet werden sowie eine Steuereinrichtung zur Durchführung des Verfahrens.
Dies hat den Vorteil, dass die Absicht eines Fahrzeuginsassen (45, 48), ein Gespräch zu führen, frühzeitig erkannt und die Lautstärke von auf den Fahrzeuginnenraum (11) einwirkenden Geräuschquellen schon vor Aufnahme des Gesprächs reduziert wird. Damit wird der Fahrzeuginsasse von einer manuellen Einstellung der Geräuschquelle oder Geräuschquellen entlastet.
摘要翻译：提出了一种用于自动地控制装置（7，8，9，10）的方法，其产生在内部的车辆（1），其特征在于，在检测到车辆内部中的呼叫的情况（11），并且其中所述装置（11）噪声（71）（7，8，9，10），以降低由它（71）所产生的噪声在车辆内部（11），其特征在于用于检测的对话状况的存在或迫近被控制检测出的车辆乘员的活动（45，48）并进行评估以及用于执行该方法的控制装置。这具有这样的优点，即即使在呼叫开始之前，车辆乘员（45,48）进行呼叫的意图被早期检测到，并且作用在车辆内部（11）上的噪声源的音量也减小。因此，车辆乘员免于手动调节噪音源或噪音源。
