Definitions
- the present invention relates to a method for adjusting a hearing system with a left-hand device and a right-hand device for binaurally supplying a user, wherein an electrical sound signal for supplying the left ear of the user and an electrical sound signal for supplying the right ear of the user are provided. Moreover, the present invention relates to a corresponding hearing system for binaural care.
- a hearing system is to be understood here in particular as a hearing aid system for the care of the hearing impaired, but also as a headset or headphones and similar device systems portable on the ear.
- Hearing aids are portable hearing aids that are used to care for the hearing impaired.
- different types of hearing aids such as behind-the-ear hearing aids (BTE), hearing aid with external receiver (RIC: receiver in the canal) and in-the-ear hearing aids (IDO), e.g. Concha hearing aids or canal hearing aids (ITE, CIC).
- BTE behind-the-ear hearing aids
- RIC hearing aid with external receiver
- IDO in-the-ear hearing aids
- ITE canal hearing aids
- the hearing aids listed by way of example are worn on the outer ear or in the ear canal.
- bone conduction hearing aids, implantable or vibrotactile hearing aids are also available on the market. The stimulation of the damaged hearing takes place either mechanically or electrically.
- Hearing aids have in principle as essential components an input transducer, an amplifier and an output transducer.
- the input transducer is usually a sound receiver, z. As a microphone, and / or an electromagnetic receiver, for. B. an induction coil.
- the output transducer is usually used as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z. B. bone conduction, realized.
- the amplifier is standard integrated into a signal processing unit. This basic structure is in FIG. 1 shown using the example of a behind-the-ear hearing aid. In a hearing aid housing 1 for carrying behind the ear, one or more microphones 2 for receiving the sound from the environment are installed.
- a signal processing unit 3 which is also integrated in the hearing aid housing 1, processes the microphone signals and amplifies them.
- the output signal of the signal processing unit 3 is transmitted to a loudspeaker or earpiece 4, which outputs an acoustic signal.
- the sound is optionally transmitted via a sound tube, which is fixed with an earmold in the ear canal, to the eardrum of the device carrier.
- the power supply of the hearing device and in particular of the signal processing unit 3 is carried out by a likewise integrated into the hearing aid housing 1 battery. 5
- a hearing system prefferably controlled by a perceptual model, in the sense that psychoacoustic dimensions, e.g. Loudness, pleasantness, listening effort, etc., to be optimized.
- psychoacoustic dimensions e.g. Loudness, pleasantness, listening effort, etc.
- the publication EP 0 661 905 A2 describes a similar method for adjusting a hearing aid and a corresponding hearing aid.
- a perceptive model is used to obtain a psychoacoustic variable, in particular loudness, on the one hand for a norm group and on the other hand for a single individual.
- setting data are determined, with which the signal transmission to a hearing device is designed or adjusted ex situ or conducted in situ.
- US 2002/0111745 A1 a portable hearing aid system.
- parameters of a hearing response can be obtained by audiometer.
- a response prediction is used to perform a basic setting of a hearing aid.
- the parameters for the left and right devices may be different. Possible causes for this can be clearly different signals on the right and left or different hearing losses on both sides.
- the resulting modifications to the configuration of the hearing system can then also be binaurally different, so that possibly produces a side-by-side auditory impression. This is impractical in particular for algorithms such as noise removal and directional microphones.
- the object of the present invention is therefore to provide a method with which the setting of a hearing system for binaural care can be better and more individualized.
- a corresponding hearing system is to be provided.
- this object is achieved by a method for adjusting a hearing system with a left-hand device and a right-hand device for binaurally supplying a user, by providing an electrical sound signal for supplying the user's left ear and providing an electrical sound signal for supplying the user's right ear and determining based on the two sound signals of a left set value for the left apparatus and a right set value for the right apparatus through a perceptual model for binaural listening and setting the left apparatus with the left set value and the right apparatus with the right set value.
- a hearing system with a left-hand device, which supplies an electrical sound signal for the supply of the left ear of the user, and a right-hand device, which supplies an electrical sound signal for the supply of the right ear of the user, wherein at least one of the two devices or another device belonging to the hearing system is a perceptive model for binaural hearing is implemented, with the basis of the two sound signals, a left set value for the left device and / or a right set value for the right device can be determined, and the left device with the left set value and / or the right device with the right set value adjustable are / is.
- the two settings for the left and right devices are the same. In this way, a symmetrical listening experience can be achieved.
- the two setting values may cause the activation or deactivation of a noise removal function and / or a directional microphone function of both devices.
- functions that significantly influence the binaural hearing impression are controlled on the basis of psychoacoustic model values.
- the sound impression, the speech understanding, and / or the localization effect may serve as the authoritative psychoacoustic quantity.
- other psychoacoustic parameters such as sharpness, roughness, hearing effort, etc. can also be used.
- the perceptual model for binaural hearing each obtains a psychoacoustic size from a perceptual model for monaural perception of each of the two devices for determining the set values. In this way it is possible to reduce the computational effort for a perceptive model for binaural hearing to distribute on two hearing aids.
- FIG. 2 a hearing aid system with a left or first hearing aid 10 and a right or second hearing aid 11 is shown.
- the two hearing aids 10, 11 are preferably wirelessly in data connection, what in FIG. 2 is indicated by the dashed lines.
- the first hearing aid 10 has a signal processing unit 12 which supplies an electrical sound signal S1 to a modeling device 13 in which a perceptual model for binaural hearing is implemented.
- This perceptive model for binaural hearing provides a statement, in particular, about which hearing impression the hearing impaired person has from a sound that he perceives over both ears.
- the binaural perception is quite different from the monaural perception, for example, a sound is perceived louder with both ears when listening with hearing than with hearing only one ear.
- psychoacoustic quantities can be obtained via perceptions that are only possible with two ears, such as localization effect.
- the signal processing unit 12 may be a signal processor, a simple microphone, or any other unit that provides an electrical signal based on an input sound.
- the second hearing device 11 also has such a signal processing unit 14.
- the latter delivers wirelessly via a corresponding communication device a second sound signal S2 to the first hearing device 10 so that it can be processed by the modeling device 13.
- the left or first adjustment signal E1 is intended for the hearing aid-internal signal processing unit 12.
- the right or second adjustment signal E2 is transmitted to the second hearing device 11 and supplied there to the signal processing unit 14.
- the setting values E1 and E2 are determined on the basis of psychoacoustic perceptual quantities for binaural hearing and are now used to adjust components of the two devices of the hearing system. It is not necessarily the units that provide the sound signals S1 and S2, are set, but it can also other components with the adjustment signals E1 and E2 of the respective hearing aid 10, 11 are set.
- the hearing aid system consists of two hearing aids 20 and 21.
- the first hearing aid 20 has a first modeling device 22, in which a perceptive model for monaural hearing is implemented.
- a first sound signal S1 originating from a microphone or any other signal processing unit of the first hearing device 20 is recorded in order to generate a first psychoacoustic variable P1.
- a second sound signal S2 which originates from a local microphone or a local signal processing unit, recorded by a modeling device 23 and processed to a second psychoacoustic size P2.
- a perceptive model for binaural hearing is implemented.
- the latter generates on the basis of the two psychoacoustic signals P1 and P2 two setting signals E1 and E2 for signal processing components 25 and 26 of the two hearing aids 20, 21.
- a binaural perceptive model is used here to combine the monaural model statements into a single statement or to change one of the two sides so that an optimal sound impression, an optimal speech understanding and / or an optimal localization effect etc. is achieved.
- parameters of both hearing aids of a hearing system can optionally be changed symmetrically on the basis of a binaural decision matrix in order to obtain a symmetrical hearing impression overall.
- the symmetrical activation or deactivation of other adaptive parameters such as noise removal or directional microphone is possible.
- the aim is also to offer a symmetrical hearing impression for the hearing aid wearer.
- the two adjustment signals E1 and E2 may be different, for example, if they affect the gain and the hearing impaired has different deficits in both ears. However, when it comes to enabling or disabling noise removal or a directional microphone, the two setting signals E1 and E2 should be the same. Thus, the two hearing aids can be synchronized on the basis of the perceptual model for binaural perception and it can be achieved a symmetrical listening experience.
