Description

Träger von hinter-dem-Ohr Luftleitungshörgeräten bzw. von Knochenleitungshörgeräten klagen häufig darüber, dass von hinten einfallender Störschall lauter als der von vorne einfallende Nutzschall übertragen wird. Dadurch wird die Verständlichkeit im Störlärm erschwert.Carrier of behind-the-ear air line hearing aids Bone conduction hearing aids often complain that from behind incident noise louder than the useful sound coming in from the front. This will the intelligibility difficult in the noise.

Durch die schon konstruktiv vorgegebene Platzierung der beiden unterschiedlichen Systeme jeweils hinter dem Ohr des Trägers lässt sich dieser Effekt ohne weitere Maßnahmen nicht beheben. Wegen der akustischen Abschattung durch die Ohrmuschel wird von hinten einfallender Schall von den Geräten besser verstärkt. Da bei Gesprächen zwischen Personen meist Augenkontakt besteht wäre es aber wünschenswert, wenn genau umgekehrt der von vorne einfallende Schall mehr verstärkt würde.By the already structurally given placement of the two different Systems behind the ear of the wearer, this effect can be without further measures do not fix it. Because of the acoustic shading by the auricle is amplified from the rear incident sound from the devices better. There in talks between people usually has eye contact, but it would be desirable if, conversely, the sound coming from the front would be amplified more.

Außerdem ist eine eventuelle Rückkopplungsproblematik u. a. von dem Abstand des Mikrophons vom Lautsprecher bzw. Vibrator abhängig. Je größer deren Abstand ist desto günstiger sind die Voraussetzungen für eine möglichst geringe Rückkopplung.Besides that is a possible feedback problem u. a. from the distance of the microphone from the speaker or vibrator dependent. The bigger their Distance is the cheaper are the requirements for one possible low feedback.

Diese Effekte können durch die Auslagerung des Mikrophons erzielt werden. Ein Ausführungsbeispiel ist in der Abbildung dargestellt. An dem Gehäuse (1), in dem sich die Batterie, die Elektronik und der Lautsprecher bzw. Vibrator befinden, ist ein justierbares Rohr (2) befestigt, durch welche die Zuleitungen für das am Ende befindliche Mikrophon (3) geführt werden. Das nach vorne gerichtete externe Mikrofon lässt sich hinsichtlich Länge und Biegeradius individuell auf die Bedürfnisse der Trägers einstellen.These effects can be achieved by outsourcing the microphone. An embodiment is shown in the figure. On the housing ( 1 ), in which the battery, the electronics and the speaker or vibrator are located, is an adjustable tube ( 2 ), through which the supply lines for the microphone located at the end ( 3 ). The front-facing external microphone can be individually adjusted to the needs of the wearer in terms of length and bending radius.

Dadurch wird der von vorne kommende Schall besser verstärkt. In schwierigen Hörumgebungen mit Störlärm ist eine Verbesserung des Nutz-Störschallabstandes um bis zu 10 dB messbar. Der Vorteil für den Träger ist dabei das wesentlich bessere Sprachverständnis.Thereby the sound coming from the front is better amplified. In difficult listening environments with noise is one Improvement of useful-Störschallabstandes measurable by up to 10 dB. The advantage for the wearer is the much better Comprehension.

In einer weitergehenden Modifikation befindet sich in dem Kerngehäuse ein zweites Mikrophon (4), welches insbesondere den Störschall aufnimmt. Durch vergleichende Signalalgorithmen werden die Signale beider Mikrophone analysiert und insofern voneinander subtrahiert, dass der Nutz-Störschallabstand weiter erhöht wird.In a further modification is located in the core housing a second microphone ( 4 ), which absorbs in particular the background noise. By comparing signal algorithms, the signals of both microphones are analyzed and subtracted from each other in such a way that the useful-Störschallabstand is further increased.
