Definitions

  • the invention relates to the area of tinnitus and more specifically to the area of treatment of tinnitus.
  • Tinnitus is the perception of unwanted sounds (tonal, hissing, clicking or roaring) without the presence of an external sound source.
  • the tinnitus can be stable or fluctuating. It can be perceived located on one or both ears, in the head, or outside the head.
  • Persistent tinnitus occurs in approximately 14% of the population and in about 65%o of the hearing impaired population (Holgers and Hakanson, 2002, Axelsson and Ringdahl, 1989, Coles, 1984, Davis, 1989). hi 2-4% of the total population, it is estimated that tinnitus plagues every day. The exact location of the timiitus generator is unknown. Although there are some indications for a peripheral origin, more recent research points toward an origination in the auditory cortex. It has for example not been possible to link audiometric data or otoacoustic emission with tinnitus.
  • tinnitus Patients with tinnitus typically report that their tinnitus is less audible and less annoying in the present of sounds. Some avoid moments of silence by choosing to live at a trafficked street or by leaving the windows open at night. This masking of the timiitus by daily life sounds motivated the development of tinnitus masker instruments. These instruments use a noise generator a few dB above the individual tinnitus threshold to mask the tinnitus. The frequency content and level of the noise generator thus has to be matched to the properties of the individual timiitus. Since the introduction of tinnitus maskers in the 1970's, a variety of such devices have become commercially available.
  • a tinnitus masker is typically placed in a hearing instrument shell. Products range from “stand alone” maskers for normal hearing to combinations of maskers and hearing instruments for the hearing impaired. Typically, tinnitus maskers are based on a simple analogue noise generator which output is added to the microphone signal or entirely replaces it. Another common type of masker is referred to as a "bedside masker", resembling a small table radio, which generates noise.
  • Tinnitus noiser The tinnitus noiser does not try to mask the tinnitus but it rather activates the inner ear with a soft broadband noise.
  • the use of the tinnitus noiser is linked to the relatively new concept of the timiitus retraining therapy (Jastreboff, 1990).
  • the tinnitus retraining therapy is based on the attempt to retrain the patients' brain so they treat their tinnitus similar to natural sounds (like most people can adapt to the refrigerator noise in their kitchen).
  • the idea behind the tinnitus retraining therapy is to retrain reflexes involving connections of the auditory nervous system and the limbic (emotional) system.
  • the timiitus retraining therapy requires intensive one-to-one directive counseling of the patient and a therapist.
  • the timiitus noiser is considered as a supporting factor in the therapy.
  • the tinnitus noiser and masker attempt to provide a peripheral stimulation of the auditory pathway.
  • a number of further suggestions have been made to methods and devices aiming towards a treatment of the tinnitus, so far without much success.
  • the objective of the present invention is to provide a method and a device for treatment of tinnitus, which brings improvement to the treatment of those suffering from tinnitus.
  • the objective is achieved by means of the method as defined in claim 1 and the device as defined in claim 10.
  • the invention aims at providing a stimulus to the central stages on the auditory pathway - as opposed to a simple noise source that aims at peripheral stimulation, i.e. a masker or a noiser.
  • the central stimulation can be achieved by manipulating the naturally occurring sound in such a way that the attention of the listener is stirred up.
  • the invention does thus not necessarily require additional noise.
  • the method maybe based on a single ear-level device or on two ear-level devices. These two devices may be working independent of each other or in a co-ordinated fashion.
  • the method may include controlling the output of the devices according to a predetermined scheme. Further the information may be sent from one device to the other device or even from each device and received by the other device.
  • a spatial or a spectral stimulus may be provided. Further a sound level stimulus may be provided. Still further a frequency and/or phase stimulus may be provided.
  • the device or devices being part of the system may comprise means for generating the signals and outputting the signals as mentioned above in connection with the method.

  • the algorithms proposed in the following utilize a technology providing the possibility of exchanging information between two ear level instruments. This link is used to yield a stimulation that aims at the central stages of the auditory pathway.
  • the invention aims at providing a stimulus to the central stages on the auditory pathway - as opposed to a simple noise source that aims at peripheral stimulation.
  • the central stimulation can be achieved by manipulating the naturally occurring sound in such a way that the attention of the listener is stirred up.
  • the algorithms proposed in the following can for example utilize a technology that is about to emerge: the possibility to exchange low-bit-rate information between two ear level instruments. This low-bit-rate or another type of link is helpful to yield a stimulation that aims at the central stages of the auditory pathway.
  • the solution comprises two connected devices. Both instruments have a spatial filter that is coordinated by the direction selector in the master instrument.
  • the spatial stimulation algorithm filters the signals in both devices in order to dynamically manipulate the perceived direction of the naturally occurring sound.
  • This approach requires a link between the signal processing in two devices. This linkage can for example be realized by a low-bit-rate wireless connection. The timing of this communication is not very critical if the simulated direction fluctuates slowly.
  • the direction selector creates a time varying direction, which is used to select or control the corresponding FIR filter in each of the two devices.
  • FIG. 2 shows four possible time courses of the direction selector. Spectral Stimulation with connected devices
  • a spectral stimulation is based on dynamic modifications of the frequency transfer function within the instrument.
  • FIG. 3 This solution comprises two connected devices. Both instruments shift the spectra of the processed signals towards higher or lower frequencies. The size of the spectral shift is determined by the frequency shift selector in the master instrument. hi a straightforward realization, one could multiply the signal in both devices with a pure tone. The magnitude of the frequency shift has to be individually chosen to yield a noticeable, but not disturbing effect.
  • the time course of the frequency selector can be chosen similarly as sketched before or as depicted in FIG. 4.
  • Another implementation could be based on spectral filtering in the two instruments, which emphasizes one frequency region and deemphasizes another frequency region.
  • This algorithm manipulates the level of the incoming sounds.
  • This algorithm resembles an automatic gain control (AGC) circuit, hi an AGC, the level of the input signal is used to calculate the appropriate amount of amplification.
  • AGC automatic gain control
  • the amplification however does not entirely depend on the input signal, but also on the sound level difference selector in the master device. Both the block diagram and the time course greatly correspond to the previous figures.
  • phase manipulation manipulates the phase of the incoming sound.
  • the phase manipulation can be a time varying phase shift or a time varying phase delay of the signal. Both the block diagram and the time course greatly correspond to the previous figures.
  • a reduction of the central stimulation can be realized by altering (typically reducing) the speed at which a change of direction (or frequency) is performed, by limiting the range of occurring directions (or frequencies) or by other means of reducing the effectiveness of the signal manipulation.
  • Another potential problem is that an input signal is needed to create the central stimulus. The following preferred embodiment does not have these two disadvantages.
  • the solution comprises two connected devices.
  • the noise source can also be replaced with other sound sources, for example via a DAI (Direct Audio Input) and may thus for example come from a tinnitus relieve CD.
  • DAI Direct Audio Input
  • the additional signal is then used to yield the spatial stimulation.
  • both instruments have a spatial filter that is coordinated by the direction selector in the master instrument.
  • central stimulation can in some extend be achieved by using a single device or disconnected devices that manipulates the direction of the sound, its spectral content, its level or its phase.
  • a central stimulus is achieved by working together with the other device or with the unaltered signal from the other ear.
