摘要： A system includes a first earpiece having an earpiece housing configured to isolate an ambient environment from a tympanic membrane by physically blocking ambient sound, a microphone disposed within the housing and configured to receive a first ambient audio signal from the ambient environment, a processor operatively connected to the microphone wherein the processor is configured to receive the first ambient audio signal from the microphone and determine if the first ambient signal exceeds a threshold sound level, and a speaker operatively connected to the processor. In a first mode of operation the processor determines the first ambient audio signal exceeds the threshold sound level and processes the first ambient audio signal to modify the first ambient audio signal. In a second mode of operation the processor determines the first ambient audio signal does not exceed the threshold sound level and reproduces the first ambient audio signal at the speaker.

摘要： An ear covering system for keeping ears warn while wearing earphones includes a pair of earphones. Each of the earphones is selectively worn in an associated one of a pair of ears. A pair of earmuffs is provided and each of the earmuffs is selectively worn on an associated one the ears. Each of the earmuffs has a hole therein and each of the earphones is selectively extended through the hole in an associated one of the earmuffs. In this way the earmuffs are worn in conjunction with the earphones. Each of the earmuffs is comprised of a fluid impermeable material to keep the ears warm in a cold environment.

摘要： Embodiments relate generally to an active hearing protection device comprising a communication device operable to provide active hearing protection to a wearer; a set of earmuffs connected to the communication device, wherein each earmuff comprises an indicator mechanism operable to indicate to the communication device when the earmuff is inserted into a user's ear, a processor operable to receive information from the set of earmuffs and the indicator mechanisms of the earmuffs, and operable to automatically power the active hearing protection device on or off based on the information received from the indicator mechanism(s). When it is determined that both earmuffs are inserted into the user's ears, the active hearing protection device is powered on, and when it is determined that at least one of the earmuffs is not inserted into the user's ear(s), the active hearing protection device is powered off.

摘要： A hearing protection system with talk-through having a pair of rigid earcups enclosing a microphone, amplifier and speaker. A concha simulator, having a volume simulating that of the concha of a human ear, is acoustically coupled to the microphone, and also to the outside through an opening in the earcup. By coupling the microphone to the concha simulator, instead of directly to the outside, the acoustic response of the talk-through more accurately represents the hearing of a user.

摘要： An ear cup for a hearing protector includes a cup-shaped outer casing, a sealing ring on a rim of the outer casing, and at least one electrical component such as a microphone. The electrical component is mounted on a flexible circuit board attached on the outer surface of the outer casing, where the outer casing includes a slit through which the flexible circuit board extends to the inside of the outer casing so as to provide electrical connections between the electrical component and an electrical circuitry inside the outer casing. Thus, there is no need for wide openings on the outer casing of the ear cup, instead only a narrow slit suffices. This facilitates achieving good noise reduction properties.

摘要： Micro-fabricated acoustic attenuation devices are described. One such device includes 1) a substrate, 2) a movable diaphragm supported by springs that anchors to the substrate, and 3) a stationary proliferated backplane which is separated by an air gap, whereby sound pressure causes the movable diaphragm to vibrate and when the sound exceeds threshold, the movable diaphragm deflects and presses against the proliferated backplane restricting further movement thus attenuates incoming sound.Another device includes 1) a substrate, 2) a movable diaphragm wherein the diaphragm has at least one hole on it, and 3) a stationary proliferated backplane which is separated by an air gap, whereby sound pressure causes the movable diaphragm to vibrate and when the sound exceeds threshold, the movable diaphragm deflects and presses against the proliferated backplane restricting further movement thus attenuates incoming sound. Methods of producing the micro-fabricated acoustic attenuation device are also described.
