摘要:
At least one exemplary embodiment is directed to a pressure management system for an earpiece comprising: a first valve, where the first valve allows air to pass from a first side of the valve to a second side more readily than from the second side to the first side an inflation channel, where the inflation channel has an outer diameter less than 5 mm; a pressure release mechanism; a pump; a stent, where the inflation channel is embedded; and a balloon, where the first valve, the inflation channel, the pressure release mechanism, the pump, and the balloon are operatively connected, where the first valve is positioned so that air from the pump passes through the first valve to inflate the balloon and where the leak rate of the air from the balloon back to the pump is less than 1% by volume per minute and where the pressure release mechanism is configured to release pressure from the balloon to the environment upon actuation, and where the pressure management system is configured to manage the inflation pressure of the balloon in an orifice.

An earpiece (100) and acoustic management module (300) for in-ear canal echo suppression control suitable is provided. The earpiece can include an Ambient Sound Microphone (111) to capture ambient sound, an Ear Canal Receiver (125) to deliver audio content to an ear canal, an Ear Canal Microphone (123) configured to capture internal sound, and a processor (121) to generate a voice activity level (622) and suppress an echo of spoken voice in the electronic internal signal, and mix an electronic ambient signal with an electronic internal signal in a ratio dependent on the voice activity level and a background noise level to produce a mixed signal (323) that is delivered to the ear canal (131).
摘要:
An earpiece is provided that can include an Ambient Sound Microphone (ASM) to measure ambient sound, an Ear Canal Receiver (ECR) to deliver audio to an ear canal, an Ear Canal Microphone (ECM) to measure a sound pressure level within the ear canal, and a processor to produce the audio from at least in part the ambient sound, actively monitor a sound exposure level inside the ear canal, and adjust a level of the audio to within a safe and subjectively optimized listening level range based on the sound exposure level. An audio interface can deliver audio content from a media player. The processor can selectively mix the audio content with the ambient sound to produce the audio in accordance with a personalized hearing level (PHL) to permit environmental awareness of at least one distinct sound in the ambient sound. Other embodiments are disclosed.
摘要:
Earpieces and methods of forming earpieces for radio frequency (RF) mitigation are provided. An earpiece is configured to be inserted in an ear canal. The earpiece includes an insertion element and a sealing section disposed on the insertion element and configured to conform to the ear canal. The sealing section is configured to substantially mitigate radio frequency (RF) transmission and to substantially isolate the ear canal from an ambient environment.
摘要:
A method and device for automatically increasing the spectral bandwidth of an audio signal including generating a “mapping” (or “prediction”) matrix based on the analysis of a reference wideband signal and a reference narrowband signal, the mapping matrix being a transformation matrix to predict high frequency energy from a low frequency energy envelope, generating an energy envelope analysis of an input narrowband audio signal, generating a resynthesized noise signal by processing a random noise signal with the mapping matrix and the envelope analysis, high-pass filtering the resynthesized noise signal, and summing the high-pass filtered resynthesized noise signal with the input narrowband audio signal. Other embodiments are disclosed.
摘要:
An orifice insertion device includes a stent and a plurality of sealing elements where each sealing element is operatively attached to the stent. Two sealing elements of the plurality of sealing elements include an expandable section configured to be disposed within the orifice and to exert a pressure on an orifice wall sufficient to seal the orifice without appreciable deformation of the orifice wall. The two sealing elements are formed from different materials and a further one of the plurality of sealing elements is configured to seal an opening of the orifice. Other embodiments are disclosed.
