摘要： In at least one embodiment, an apparatus for generating a simulated vehicle sound is provided. At least one parameter module receives a first driver throttle signal and to transmit a first input signal indicative of a first simulated vehicle sound. An engine sound generator block audibly generates a first simulated vehicle sound in response to the first input signal. An engine sound removal block is operably coupled to a microphone that receives a first microphone input signal. The first microphone input signal includes first environmental noise associated with a vehicle exterior environment and the first simulated vehicle sound. The engine sound removal block is configured to filter the first simulated vehicle sound from the first microphone input signal to determine the first environmental noise. The engine sound generator generates a second simulated vehicle sound that is louder than the first environmental noise.

摘要： A headphone and method are provided. The headphone includes a headphone housing and a resilient cushion attached to the housing to define a chamber with the housing for enclosing the user's ear. An assembly is disposed in the housing proximate to a distal end and has a plurality of blades moveable between at least one open position and a closed position. In the closed position, the blades define a distal surface of the housing. In the open position, the assembly defines an aperture in the housing. The aperture allows sound communication from outside the housing into the chamber. The headphone is in communication with at least one external device and is programmed to receive a signal from the external device. The assembly to moves between the open position and the closed position based on the signal.

摘要： An electronic hearing protector includes an ear cup assembly comprising a front exterior microphone that provides a front microphone signal and a rear exterior microphone that provides a rear microphone signal. A processor receives and digitizes the front microphone signal and the rear microphone signal, and provides a front channel signal and a rear channel signal indicative thereof respectively. A filter receives the rear channel signal and has a cut-off frequency value that provides a high-frequency roll-off and a notch at a notch filter frequency value that is less than the cut-off frequency value, where the filter provides a filtered signal. A first signal indicative of the front channel signal and a second signal indicative of the filtered signal are summed, and a signal indicative of the summed signal is provided to a speaker within the ear cup that provides an audio signal within the first ear cup indicative of the summed signal.
