摘要： The invention relates to a method for locating sound-emitting targets by means of a receiving antenna 10, the receiving signals 14 of which are fed to a direction generator 16 for generating at least three directional characteristics, said characteristics being offset from one another. In an intended embodiment, both sides of a main lobe 28 are overlapped by the main lobes 26 of adjacent directional characteristics in a radiation pattern such that both said main lobes 26 come into contact with or cross each other at the level of the reception angle ϑ at which the main lobe 28 of the central directional characteristic has its maximum 30. Amplitude functions FA, FB, FC that are directionally dependent are produced on the basis of said main lobes 26, 28. The subsequent calculated summation function FS of the amplitude functions FA, FC is differentiated twice in order to determine the second derivative 50 thereof. The local maxima 56 resulting from the second derivative function 50 indicate possible, potential signal directions. A statistical analysis method ascertains actual signal directions with the corresponding signal strengths from said possible, potential signal directions z
i. The invention further relates to a device for performing such a method.-

摘要： A call other than a conversion partner call and various sounds are detected by input audio signals from plural microphones without deteriorating a voice recognition precision. A hearing aid apparatus according to the present invention corrects a frequency characteristic of the call voice other than the conversation partner voice based on an arrival direction of the call voice other than the conversation partner voice, which is estimated based on the audio signal converted by the plural microphones, checks a call word standard pattern representing features of a phoneme and a syllabic sound based on other voice data picked up by using the microphones having one characteristic against a call voice other than the conversation partner voice in which the frequency characteristic is corrected by the frequency characteristic correction processing unit to determine whether the call voice is a call word, and forms a directivity in the direction other than the arrival direction of the voice of the conversation partner. Then, the hearing aid apparatus according to the present invention corrects the frequency characteristic of the call voice other than the conversation partner voice so as to provide the same characteristic as that of the microphones at the time of creating the audio standard pattern.

摘要： A navigational device (10) for assisting a scuba diver in determining a direction toward and a distance from a dive boat (12) or to a buoy near the shore at which point the dive originated. The navigational device (10) includes a transponder unit (16) carried by a boat (12) and an interrogator unit (34) carried by a diver. The transponder unit (16) repeatedly pulses an identification signal to be received by the interrogator unit (34). The direction from which the signal is received is determined and displayed. When the distance to the boat (12) is required, a distance request signal is emitted from the interrogator unit (34) and a responding signal is emitted by the transponder unit (16). The distance between the diver and the boat is then determined by the interrogator unit as a function of the time elapsed between the emission of the distance request signal and receipt of the responding signal.

摘要： Provided is a device for detecting sound outside vehicle capable of detecting sounds outside the vehicle with high accuracy in various surrounding environments.
A sound source direction detecting ECU 1 acquires sound collection information about sounds outside a vehicle which are collected by microphones 2A to 2G. The sound source direction detecting ECU 1 acquires traveling road information about the vicinity of a host vehicle on the basis of the acquired sound collection information. When the traveling road information is acquired, the sound source direction detecting ECU 1 adjusts the sound collection characteristics of the microphones 2A to 2G on the basis of the traveling road information.摘要翻译： 提供了一种用于在各种周围环境中以高精度检测汽车外部的声音的车辆外部的声音检测装置。 声源方向检测ECU1获取由麦克风2A〜2G收集的车外的声音的声音收集信息。 声源方向检测ECU1基于所获取的声音收集信息来获取关于本车辆附近的行驶道路信息。 当获取行驶道路信息时，声源方向检测ECU1基于行驶道路信息来调节麦克风2A至2G的声音收集特性。

摘要： Zur Bestimmung einer Einfallsrichtung eines Signals (S1,S2) einer akustischen Signalquelle wird mithilfe eines Richtmikrofonsystems (RMS,RM1,RM2), das mindestens zwei Mikrofone (M1,...M5) aufweist, zuerst eine Mehrzahl von Richtmikrofonsignalen (RMS1,RMS2) erzeugt, deren richtungsabhängige Empfindlichkeitsverteilungen jeweils in einer Richtung ein Minimum aufweisen. Eine Bewertung der Richtmikrofonsignale (RMS1,RMS2) nach einem Maß ermöglicht ist, das Richtmikrofonsignal (RMS1,RMS2), das am meisten durch die dazugehörige richtungsabhängige Empfindlichkeitsverteilung beeinflusst ist, zu bestimmen, wobei der Einfallsrichtung diejenige Richtung zugeordnet wird, in der das Minimum der Empfindlichkeitsverteilung dieses Richtmikrofonsignals (RMS1,RMS2) liegt.
