20140072125 | ACOUSTIC DIAGNOSIS AND CORRECTION SYSTEM - An acoustic monitoring system includes a portable acoustic detection device, a sound analysis device and a confidence level device. The portable acoustic detection device is capable of receiving sound at one or more locations near a sound-producing device. The sound analysis device receives the sound from the portable sound detection device, determines a diagnosis based on a comparison between the sound and pre-recorded sound data, and outputs the diagnosis to the portable acoustic detection device. The sound analysis device also determines a corrective action for inhibiting the sound, which is also output to the portable sound detection device. The confidence level device determines a confidence level of the diagnosis indicating a likelihood that the diagnosis is successfully diagnosed. | 2014-03-13 |
20140072126 | APPARATUS AND METHOD FOR DETERMINING A MEASURE FOR A PERCEIVED LEVEL OF REVERBERATION, AUDIO PROCESSOR AND METHOD FOR PROCESSING A SIGNAL - An apparatus for determining a measure for a perceived level of reverberation in a mix signal consisting of a direct signal component and a reverberation signal component, has a loudness model processor having a perceptual filter stage for filtering the dry signal component the reverberation signal component or the mix signal, wherein the perceptual filter stage is configured for modeling an auditory perception mechanism of an entity to obtain a filtered direct signal, a filtered reverberation signal or a filtered mix signal. The apparatus furthermore has a loudness estimator for estimating a first loudness measure using the filtered direct signal and for estimating a second loudness measure using the filtered reverberation signal or the filtered mix signal, where the filtered mix signal is derived from a superposition of the direct signal component and the reverberation signal component. The apparatus furthermore has a combiner for combining the first and the second loudness measures to obtain a measure for the perceived level of reverberation. | 2014-03-13 |

20140072128 | AUDIO PACING DEVICE - There is provided a audio pacing device including a sensing unit, such as heart rate monitoring unit, to obtain a parameter, such as heart-beat rate (pulse), of a user in physical exercise, a memory to store a plurality of audio signals having predetermined tempo indications (e.g. beats per minute values); and a processing unit configured to (1) determine whether the intensity of the parameter of the user should be increased, decreased or maintained by using the parameter of the user from the heart rate monitor and a predetermined reference value, and (2) dynamically select and render an audio signal having (or adjusted to have) an audio-tempo that enables the user to accordingly increase, decrease or maintain exercise intensity, respectively | 2014-03-13 |
20140072129 | METHOD AND APPARATUS FOR DETECTING INSERTION OF EXTERNAL AUDIO OUTPUTTING DEVICE IN ELECTRONIC DEVICE - Apparatus and method for detecting insertion of an external audio outputting device in an electronic device. The apparatus comprises an earphone socket into which the external audio outputting device is inserted. The earphone socket includes first and second terminal sets, each terminal set having at least two electrical contacts. A controller determines an insertion condition if each of the terminal sets is shorted, and determines a non-insertion condition if only one terminal set is shorted, or if neither of the terminal sets is shorted. | 2014-03-13 |
