    摘要: A sound masking system for shaping the ambient noise level in a physical environment. The sound masking system comprises a networked and distributed system having a number of master units coupled together and to a control unit. One or more of the master units may include satellite sound masking units which function to reproduce the sound masking signal generated by the master sound masking unit. Each of the master units is addressable over the network by the control unit enabling the control unit to program the contour, spectral band, and gain characteristics of the sound masking output signal. The system may also include a remote control unit which provides the capability to tune and adjust each master sound masking unit in situ without requiring physical access through the ceiling installation. According to another aspect, there is a networked paging system with individually addressable speaker units for announcing a paging signal selected from a number of paging signals.

    摘要: A method and a device for actively influencing the intake noise of an internal combustion engine are disclosed. The device for carrying out said method comprises a controller (7), which records the actual noise value (I) by means of a microphone (16) and compares said actual noise value with a set noise signal, which is dependent upon engine speed (D). Further parameters (P) may also be measured, such as, for example, the position of the throttle (12). A comparison signal is generated by comparing the actual noise value and the set noise value. Said comparison signal influences a control signal (Ages)which is also dependent upon the speed of the internal combustion engine. The control signal (Ages) is fed to a loudspeaker (14) which generates a correcting noise (20). Said correcting noise (20) is superimposed on the intake noise (21) to generate the actual noise value (22). The actual noise value should correspond as closely as possible to the set noise value. In this manner, it is not only possible to reduce the level of intake noise, but also to tailor the intake noise to a desired set sound. Similarly, the intake noise can be freely shaped, within the limits of the loudspeaker output, whereby the driver of the vehicle can be given an acoustic feedback, for example under specified operating conditions.

    摘要: A personal audio device includes a personal audio device housing; a transducer mounted on the housing for reproducing an audio signal including an anti-noise signal (anti-noise) for countering effects of ambient audio sounds in an acoustic output of the output transducer; a reference microphone mounted on the housing for providing a reference microphone signal (ref) indicative of the ambient audio sounds; and a processing circuit (30) within the housing. The processing circuit (30) adaptively generates the anti-noise signal (anti-noise) from the reference microphone signal (ref) such that the anti-noise signal (anti-noise) causes substantial cancellation of the ambient audio sounds. The processing circuit (30), in response to determining that an amplitude of acoustic leakage of the source audio into the reference microphone is substantial with respect to an amplitude of the ambient audio sounds, takes action to prevent improper generation of the anti-noise signal (anti-noise).

    摘要: Boomless-microphones are described for a wireless helmet communicator with siren signal detection and classification capabilities. An acoustic component receives an audio signal and comprises a left acoustic sensor and a right acoustic sensor. The left acoustic sensor is mountable or attachable to the surface of a left wall of a helmet and the right acoustic sensor is mountable or attachable to the surface of a right wall. A speaker component can generate an echoless audio signal via signal inversion of the audio signal, outputs to a left speaker mountable or attachable to a left ear area of the helmet and a right speaker mountable or attachable to a right ear area of the helmet. A signal enhancement component can increase an intensity of the first audio signal associated with an emergency siren based on a determined proximity of an emitting emergency vehicle or emergency object to the device.
