Definitions

  • the natural beam-forming characteristics of the HRTF at frequencies of 500 Hz, 1 kHz, 2 kHz, 4 kHz. It might be seen that at 2 kHz and above the HRTF provides for a natural beam-forming which is very similar to that of a cardioid-type microphone.
  • the head shadow of the individual provides for an increased amplification on the ipsi-lateral side by about 5 dB compared with the amplification towards the contra-lateral side. Therefore and with an eye on fig. 2 , the HRTF provides for sufficient beam-forming at the ipsi-lateral hearing device, so that no additional technical beam-forming is necessitated at the "primariy", the ipsi-lateral input converter arrangement.
  • Acoustical sources which are to be perceived in the area F 1 are especially sources as occurring in telephone applications.

Claims (10)

  1. Procédé pour la manufacture d'un signal audible, destiné à être perçu par un individu, en dépendance d'une source acoustique de signal, ledit individu portant un appareil auditif de l'oreille droite et un appareil auditif de l'oreille gauche, ayant respectivement un agencement convertisseur d'entrée de l'oreille droite et de l'oreille gauche, et ayant un agencement convertisseur de sortie de l'oreille droite et de l'oreille gauche:
    - le signal d'entrée de l'agencement convertisseur de l'oreille droite étant dépendant du signal de sortie de l'agencement convertisseur d'entrée de l'oreille droite,
    - le signal d'entrée de l'agencement convertisseur de l'oreille gauche étant dépendant du signal de sortie de l'agencement convertisseur d'entrée de l'oreille gauche, comprenant:
    - l'établissement d'une dépendance prédominante du signal d'entrée de l'agencement convertisseur de sortie contra-latéral du signal de sortie de l'agencement convertisseur d'entrée ipsi-latéral si une source acoustique à être perçu se situe latéralement de la tête de l'individu
    caractérisé par la désactivation du dépendance des signaux d'entrée à l'agencement convertisseur de sortie ipsi-latéral du signal de sortie de l'agencement convertisseur d'entrée contra-latéral, et l'établissement dudit dépendance prédominante par la réduction de la dépendance dudit signal d'entrée dudit agencement convertisseur de sortie contra-latérale du signal de sortie dudit agencement convertisseur d'entrée contra-latéral, uniquement si ladite source acoustique se situe dans une étendue (F1) de direction d'arrivée DOA, où 45 ⁢ ° ≤ DOA ≤ 135 ⁢ °
    Figure imgb0007
     225 ⁢ ° ≤ DOA ≤ 315 ⁢ °
    Figure imgb0008
    relative à la direction vers l'avant du individu, et la source est écarté d'une des oreilles de l'individu par 0.3 m au maximum, et où «ipsi-latéral» se réfère au côté de la tête de l'individu plus proche à une source acoustique, et «contra-latéral» se réfère au côté de la tête de l'individu qui est plus éloigné d'une source acoustique latérale.
  2. Procédé selon la revendication 1, comprenant la formation de faisceau binaurale par l'établissement du dépendance du signal d'entrée dudit agencement convertisseur de sortie de l'oreille droite du signal de sortie dudit agencement convertisseur de sortie de l'oreille gauche, et par l'établissement du dépendance dudit signal d'entrée dudit agencement convertisseur de sortie de l'oreille gauche dudit signal de sortie dudit agencement convertisseur d'entrée de l'oreille droite, au moins pour DOA en dehors de ladite étendue.
  3. Procédé selon la revendication 2, comprenant l'exécution de ladite formation de faisceau binaurale exclusivement pour un DOA situé dans une seconde étendue de DOA.
  4. Procédé selon l'une des revendications 1 à 3, comprenant la temporisation de l'influence desdites signaux de sortie des agencements convertisseurs d'entrée de l'oreille droite et de l'oreille gauche respectivement sur les signaux d'entrée des agencements convertisseurs de sortie de l'oreille gauche et de l'oreille droite, plus par une quantité fixe que par la temporisation de l'influence dudit signaux de sortie des agencement convertisseurs d'entrée de l'oreille droite et de l'oreille gauche sur lesdits signaux d'entrée des agencements convertisseurs de sortie de l'oreille droite et de l'oreille gauche respectivement.
  5. Procédé selon la revendication 4, ladite quantité fixe étant sélectionnée d'être au moins approximativement égale au temps de transit d'un signal acoustique dans la bande de fréquence audible de l'une oreille à l'autre, autour d'une tête humaine.
  6. Procédé selon l'une des revendications 1 à 5, comprenant de plus l'établissement en situ et pour au moins la bande de fréquence audible, pour lesdites agencements convertisseurs d'entrée de l'oreille droite et de l'oreille gauche, la capacité d'effectuer de la formation de faisceau monaurale, résultant en une amplification maximum pour un DOA venant d'un hémisphère latéral de l'individu et résultant en une amplification minimum pour un DOA venant d'un hémisphère côté-tête de l'individu.
  7. Procédé selon la revendication 6, ledit établissement étant effectué principalement par l'exploitation de la fonction de transfert de tête respective.
  8. Procédé selon l'une des revendications 1 à 7, comprenant la désactivation de la formation de faisceau binaurale dans une étendue entre au plus 45° et au moins 315°.
  9. Procédé selon l'une des revendications 1 à 8, comprenant l'accomplissement d'un changement de dépendance de signal dans une manière décroissante.
  10. Procédé selon l'une des revendications 1 à 9, l'établissement desdites dépendances desdites signaux d'entrée desdits agencements convertisseurs de sortie des signaux de sortie desdits agencements convertisseurs d'entrée comprenant un traitement de signal en mode de fréquence et effectuant un changement d'une dépendance de signal comprenant effectuant le changement dudit dépendance de signal subséquemment, premièrement d'une première groupe de fréquences spectraux et ensuite d'une seconde groupe de fréquences spectraux différentes.
