An In The Ear (ITE) microphone improves the acoustic response of a Behind The Ear (BTE) Implantable Cochlear Stimulation (ICS) system during telephone use. An acoustic seal provided by holding a telephone earpiece against the ear provides improved coupling of low frequency (up to about 1 KHz) sound waves, sufficient to overcome losses due to the near field acoustic characteristics common to telephones. In a preferred embodiment, the ITE microphone is connected to a removable ear hook of the BTE ICS system by a short bendable stalk.

An active acoustic noise reduction system which comprises a single input transducer and an output actuator that are physically located next to each other in the same location. In one embodiment, the input transducer and the output actuator are a hybrid represented by a single element. The active noise reduction system is located as close as possible to the noise source and functions to generate an antinoise cancellation sound wave with minimum delay and opposite phase with respect to the noise source. The noise reduction system also comprises a non linearity correction circuit, a delayed cancellation circuit and variable gain amplifier. The system provides user control of the quiet zones generated by the system by varying the gain of the variable gain amplifier. The system provides a user with the ability In one embodiment, an echo canceler is utilized to remove echoes fed back from the output actuator. In another embodiment, an input decoder is used instead of an echo canceler to remove feedback picked up from the output actuator.

Described herein are compliant electroactive polymer transducers for use in acoustic applications. A compliant electroactive polymer transducer includes a compliant electroactive polymer at least two electrodes. For sound production, circuitry in electrical communication with the transducer electrodes is configured to apply a driving signal that causes the electroactive polymer to deflect in the acoustic range.

The invention discloses a liquid pressure pipe leakage measuring method and apparatus which comprises the following steps: positioning the two sensors inside the measuring pipe on the two sides explored pipe wire of the tested leakage pipe to obtain the noise signal, doing high pass filter, signal amplify and auto-gaining to the noise signal, finding the corresponding audio range signal, sending the noise signal to the leakage location analysis system by the cable on by wireless type, ascertaining the time differential of the two sensors by the multi-analysis of the two signals by the leakage location analysis system, computing the distance between the leakage point to the two sensors by the time differential and the transmitting speed of the distance and the sound wave of the two sensors.

A non-invasive ocular therapy for vision disorders is provided. First and second electrodes of a direct current source are electrically contacted so as to deliver current to and / or about an area proximal one or more eyes of a subject. A direct electrical current of between about 1-800 microamps, at a resistance assumption of about 500 ohms, is generated between the electrodes for a preselected duration. Preferably, the direct electrical current is generated at a select frequency profile as a function of time, and with a carrier signal of about 10,000-12,000 hertz. Advantageously, the subject therapy is augmented via application of light energy to the eye(s), as well as by the application of infrasonic sound waves directly into eyes.

A method and apparatus for speech synthesis utilize a plurality of stored prosodic templates, each having been generated based on a series of enunciations of a single syllable executed in accordance with the rythm, pitch and speech power variations of an enunciated sample speech item, whereby the templates express rythm, speech power and pitch characteristics of respectively different sample speech items. Data representing an object speech item are converted to a sequence of acoustic waveform segments which respectively express the syllables of the speech item, the number of morae (syllable intervals) and the accent type of the speech item are judged and a prosodic template having the same number of morae and accent type is selected, and waveform shaping is applied to the waveform segments such as to match the rythm, speech power and pitch characteristics of the object speech item to those expressed by the selected prosodic template. The shaped acoustic waveform segments are then linked to form a continuous acoustic waveform, thereby obtaining synthesized speech which closely resembles natural speech.
