Abstract
Description
Die Erfindung bezieht sich auf ein Verfahren, welches mit den Möglichkeiten der digitalen SignalprozessortechnikThe invention relates to a method which with the possibilities of digital signal processor technology
- 1) die einfache individuelle Aufnahme eines Audiogramms für jeden Hörkanal als Grundlage1) the simple individual recording of an audiogram for each auditory channel as basis
- 2) für die frequenz- und kanalabhängige, gehörrichtige Aufbereitung von NF- Signalen (Musik) für die Wiedergabe z. B. über Kopfhörer bei Hörbehinderten erlaubt. (Patentanspruch)2) for frequency- and channel-dependent, aurally correct processing of NF- Signals (music) for playback z. B. on headphones for the hearing impaired allowed. (Claim)
Durch die Betätigung der Taste Programm und links, oder rechts funktioniert das Gerät wie ein Audiometer (DIN 45620) nach B´k´sy, und zwar für den linken und rechten Kanal separat.It works by pressing the program button and left or right Device like an audiometer (DIN 45620) according to B'k'sy, for the left and right channel separately.
Dadurch kann der Hörbehinderte durch einen selbstdurchgeführten audiometrischen Hörtest, dem Gerät sein spezifisches Hörverhalten in einem Frequenzbereich von ca. 100 Hz bis ca. 18 Khz separiert für den linken und rechten Kanal mitteilen. Dabei gibt die Elektronik die Frequenz in den bei Audiometern üblichen Schriften vor. Durch Betätigung der Tasten laut oder leise wird die Hörschwelle über den Frequenzbereich und für jeden Kanal separat ermittelt.This enables the hearing impaired to perform a self-performed audiometric Hearing test, the device's specific hearing behavior in a frequency range of approx. Communicate 100 Hz to approx. 18 Khz separately for the left and right channel. Here The electronics specify the frequency in the fonts common to audio meters. By pressing the buttons loudly or quietly, the hearing threshold is exceeded Frequency range and determined separately for each channel.
Ist der individuelle Lernvorgang abgeschlossen, wird durch Betätigung der Taste PLAY das Gerät für den individuellen gehörrichtigen Abspielvorgang mit einer beliebigen genormten Schallquelle (CD-Player oder Cassettenrecorder- anschließbar über genormte Chinch-Chinch-Verbinder) vorbereitet.When the individual learning process is completed, pressing the key PLAY the device for the individual aurally correct playback process with a any standard sound source (CD player or cassette recorder) can be connected prepared using standardized chinch-chinch connectors).
Jetzt bewirken die Tasten laut oder leise die Lautstärkeänderung des angeschlossenen Kopfhörers.Now the buttons change the volume of the connected headphones.
Das Stereo-Signal (es wird nur ein Kanal beschrieben) gelangt über ein Filter (1) einen schnellen Analog-Digital-Wandler (2) in den Signalprozessor. Dieser berechnet Aufgrund der im Testlauf ermittelten individuellen Hörbehinderung (Durchlaßkurve) eine gegenläufige Verstärkungskurve, so daß sich für jede Frequenz des Betroffenen eine für Ihn gehörrichtige Wiedergabe ergibt.The stereo signal (only one channel is described) passes through a filter ( 1 ) to a fast analog-digital converter ( 2 ) in the signal processor. On the basis of the individual hearing impairment (pass curve) determined in the test run, the latter calculates an opposing gain curve, so that for every frequency of the person concerned there is an accurate reproduction for him.
Der Proband hört die Frequenz von 1 kHz mit einer Hörminderung von 40 dB auf dem linken Kanal aber nur 10 dB auf den rechten Kanal. Daraus errechnet das Gerät jetzt eine Erhöhung der Musikfrequenz-anteile von 1 kHz um 40 dB auf dem linken und um 10 dB auf dem rechten Kanal, jeweils ausgehend von dem normalerweise gehörrichtigen Eingangssignal. The subject stopped the frequency of 1 kHz with a hearing loss of 40 dB the left channel but only 10 dB on the right channel. The device calculates from this now an increase of the music frequency components of 1 kHz by 40 dB on the left and by 10 dB on the right channel, starting from that normally aurally correct input signal.
Damit wird dem Kopfhörer für dieses Frequenzspektrum über den Digital-Analog- Wandler (5) und ein Ausgangsfilter (6) ein individuelles, für jeden Kanal gesondert errechnetes Signal zugeführt.An individual signal, calculated separately for each channel, is thus supplied to the headphones for this frequency spectrum via the digital-analog converter ( 5 ) and an output filter ( 6 ).
