摘要： System and method for modification of fluid environment of an ear. In one embodiment, the system includes an earpiece mountable within an ear canal. The earpiece includes a fluid delivery path for fluid to be delivered to the ear and a fluid removal path for fluid to be removed from the ear. The system also includes an electronics housing. The electronics housing may be directly mounted on the earpiece or positioned outside the ear. The system further includes an electrochemical gas generating device positioned within the electronics housing. In use, oxygen or the like is generated by the electrochemical gas generating device and is conveyed through the fluid delivery path of the earpiece, emerging from the earpiece distal end. The gas released from the earpiece causes fluid in the ear to be swept into the fluid removal path of the earpiece and eventually expelled to the outside of the ear.

摘要： An array of microphones utilizes two sets of two microphones for noise suppression. A primary microphone and secondary microphone of the three microphones may be positioned closely spaced to each other to provide acoustic signals used to achieve noise cancellation. A tertiary microphone may be spaced with respect to either the primary microphone or the secondary microphone in a spread-microphone configuration for deriving level cues from audio signals provided by tertiary and the primary or secondary microphone. The level cues are expressed via an inter-microphone level difference (ILD) which is used to determine one or more cluster tracking control signals. The ILD based cluster tracking signals are used to control the adaptation of null-processing noise cancellation modules. A noise cancelled primary acoustic signal and ILD based cluster tracking control signals are used during post filtering to adaptively generate a mask to be applied against a speech estimate signal.
摘要翻译：一组麦克风使用两组麦克风进行噪声抑制。三个麦克风的主麦克风和次麦克风可以彼此紧密地定位，以提供用于实现噪声消除的声信号。第三麦克风可以在扩展麦克风配置中相对于主麦克风或辅助麦克风间隔开，以从由三级麦克风和主麦克风或辅助麦克风提供的音频信号导出电平提示。通过用于确定一个或多个集群跟踪控制信号的麦克风间级差（ILD）来表示电平提示。基于ILD的群集跟踪信号用于控制空处理噪声消除模块的适应。在后滤波期间使用噪声消除的主声信号和基于ILD的群集跟踪控制信号来自适应地生成针对语音估计信号应用的掩码。

摘要： An apparatus for providing hearing protection to a wearer includes an incorporated set of eyewear having an eyewear frame. In one version, a pair of ear muffler tubes are coupled to the supporting members of the frame or made integral therewith, the muffler tubes each extending to the entrance of the ear canal of a person to reduce the level of ambient noise in the ear canal and includes at least one muffler tube of appropriate dimensions sufficient to isolate the ear canal from ambient air that substantially reduces the acoustic impedance at the entrance of the ear canal over a wide range of audible sound frequencies. A connecting tube for attachment to the ear canal is coupled to the ear muffler tube.

摘要： Systems and methods for noise suppression using noise subtraction processing are provided. The noise subtraction processing comprises receiving at least a primary and a secondary acoustic signal. A desired signal component may be calculated and subtracted from the secondary acoustic signal to obtaining a noise component signal. A determination may be made of a reference energy ratio and a prediction energy ratio. A determination may be made as to whether to adjust the noise component signal based partially on the reference energy ratio and partially on the prediction energy ratio. The noise component signal may be adjusted or frozen based on the determination. The noise component signal may then be removed from the primary acoustic signal to generate a noise subtracted signal which may be outputted.

摘要： A semi-insert hearing protector includes a thin-walled enclosure sized substantially to that of the outer ear of a wearer, the enclosure being made from a rigid or semi-rigid material and secured to the head of said wearer by means of an adjustable headband. A short tube extends from the enclosure for communication with the ear canal, the short tube being made from a rigid or semi-rigid material and including a flexible cuff disposed over the tube made from a resilient material. The enclosure contains sound absorbing material configured to vary the frequency characteristic of sound attenuation by the semi-insert.
