Definitions

  • the invention relates to a hearing instrument, e.g. a hearing aid that has a mechanical, manually operable volume control and whose volume can also be adjusted by remote control and a method for adjusting the volume of such a hearing instrument by means of the mechanical, manual volume control.
  • a hearing instrument e.g. a hearing aid that has a mechanical, manually operable volume control and whose volume can also be adjusted by remote control and a method for adjusting the volume of such a hearing instrument by means of the mechanical, manual volume control.
  • Hearing instruments can be designed for example as hearing aids.
  • a hearing aid is used to supply a hearing-impaired person with acoustic ambient signals that are processed and amplified for compensation or therapy of the respective hearing impairment. It consists in principle of one or more input transducers, of a signal processing device, of an amplification device, and of an output transducer.
  • the input transducer is typically a sound receiver, e.g. a microphone, and / or an electromagnetic receiver, e.g. an induction coil.
  • the output signal generator is usually as an electroacoustic transducer, z. As miniature speaker, or as an electromechanical transducer, z.
  • the output signal generator generates output signals that are routed to the patient's ear and are intended to produce a hearing perception in the patient.
  • the amplifier is usually integrated in the signal processing device.
  • the hearing aid is powered by a battery integrated into the hearing aid housing.
  • the essential components of a hearing aid are usually arranged on a printed circuit board as a circuit carrier or connected thereto.
  • hearing instruments may also serve as so-called tinnitus maskers be executed.
  • Tinnitus maskers are used to treat tinnitus patients. They produce from the respective hearing impairment and depending on the principle of action also dependent on ambient noise acoustic output signals that can contribute to reducing the perception of annoying tinnitus or other ear noises.
  • hearing instrument should also be understood tinnitus masker and other such devices.
  • Hearing aids include a signal processing device whose operation can be changed by programming or parameter setting.
  • Operating system or firmware of the signal processing device can be programmed as software. There may be a manual or automatic selection option for selecting one of several different programmed acoustic signal processing algorithms, also referred to as hearing programs.
  • Operating parameters such as gain (volume), frequency-dependent gain spectra, frequency compression, frequency transformation, noise suppression functions or targeted suppression of repetitive or constant interference signals can be set.
  • modes of operation with direct reception of transmitted acoustic signals from telephones or consumer electronics or a remote control through a receiving coil also referred to as Telecoil, can be activated. Countless other operating parameters are conceivable that can be changed on a hearing aid.
  • wireless remote controls for hearing aids are known.
  • One advantage of wireless remote controls also known as Remote Control Unit or RCU for short, is their ease of manual operation. Hearing aids are relatively small and adjusting devices on hearing aids are therefore also small and can therefore be difficult to use.
  • remote controls are usually larger and therefore may have larger, easier to operate controls such as buttons.
  • a setting option for hearing aids the hearing aid wearer usually use in everyday life, is the volume.
  • the volume requirements can change frequently depending on the situation and the environment. Although these altered requirements can be partially recognized automatically by the signal processing, there remain numerous situations in which hearing aid wearers want to adjust the volume themselves.
  • volume control For manual adjustment of the volume of hearing aids themselves different actuators are previously known.
  • non-mechanical touch-sensitive sensors such as touch screens will be used as the volume control.
  • mechanical volume control are used, which can be performed, for example, as a push-button or as a rocker switch.
  • Not least volume control are known, which are designed as a knob.
  • volume controllers which are designed as rotary control
  • endless controllers which can be turned on endlessly without end stop
  • controllers with limit stops For infinite knobs, turning the knob will change the volume and the knob position will not be fixed to a specific volume setting. For example, infinite knobs have no fixed, constant rotational position for minimum or maximum volume.
  • Knobs with end stops are often perceived by hearing aid wearers as more comfortable and intuitive to operate, because the position of the rotary knob is assigned a specific volume setting.
  • the minimum or maximum volume setting is usually permanently assigned to the respective end stop of the volume control.
  • the volume of hearing aids with manually operable knob with end stop can also be adjusted frequently by remote control. Adjusting by remote control changes the volume setting, but not the position of the rotary control. This results in the problem that the normally fixed assignment of the respective position of the rotary control is no longer given to the respective volume setting.
  • the adjustment of the volume by remote control has in this sense priority over the setting that results from the position of the rotary control. The problem is the operation, if after operation by remote control, the knob is pressed again. If then the priority of the remote control is canceled and instead the setting is again activated, which is assigned to the rotational position of the rotary control, volume jumps can occur. So if, for example, the knob is set to maximum volume and the remote control has set the minimum volume, then pressing the rotary control would cause the maximum volume to be suddenly activated again.
  • the object of the invention is to provide a hearing aid with designed as a knob with end stop volume control and a method for operating such a hearing aid that allows a simpler, more intuitive, less problematic and volume jumps free manual adjustment of the volume on the knob despite previous adjustment by remote control.
  • the invention solves this problem by a method and by a hearing aid with the features of the independent claims.
  • a basic idea of the invention consists in a method for adjusting the volume setting of a hearing instrument with a manually operable volume control, which is designed as a rotary control, in which each rotational position an associated volume setting is permanently assigned.
  • a change in the rotational position of the rotary control is detected.
  • a momentary rotary position of the rotary control is determined during the change.
  • the instantaneous rotational position is compared with a comparison rotational position.
  • the volume setting of the hearing instrument according to the instantaneous rotational position is changed only when the instantaneous rotational position has at least temporarily assumed the comparison rotational position.
  • the rotational position which is assigned to the smallest possible volume setting is predetermined as the comparison rotational position. This ensures that any volume jumps occur only to small or vanishing volumes and thus have a minimum of unpleasant effect on the hearing aid wearer.
  • the hearing aid wearer requires no knowledge of the current volume setting of the hearing instrument. Since volume jumps are prevented, he can completely safely back and forth the volume control until he becomes active again by reaching the required comparison rotational position.
  • the rotational position given as the comparison rotational position which is assigned to the current volume setting of the hearing instrument. This ensures that volume jumps are completely prevented. Then the volume control will be active only when its rotational position corresponds to the current volume setting of the hearing instrument. Figuratively speaking, this process is similar to "catching" or activating the volume control by reaching the currently effective volume setting.
  • the hearing aid wearer requires this no Knowledge of the current volume setting of the hearing instrument. Since unpleasant jumps in volume are prevented, he can completely safely turn the volume control back and forth until he becomes active again by reaching the required comparison rotational position.
  • the volume settings assigned to the respective rotational positions are first determined.
  • the comparison of the instantaneous rotational position with a comparison rotational position is then made on the basis of a comparison of the assigned volume settings.
  • This is favorable insofar as the volume setting is the relevant measure, since even volume jumps should be avoided or at least alleviated.
  • the rotational position of the knob is not relevant as such but only to the effect of interest that a volume setting is permanently assigned.
  • the rotational position is usually not known otherwise than by the associated volume setting. Thus, it represents a simplification and relief for the process, if instead of the rotational position, the volume setting is based.
  • the comparison volume setting assigned to this rotational position is therefore used.
  • the volume setting of the hearing instrument is additionally adjustable by remote control regardless of the rotational position of the rotary control.
  • the problem of volume jumps described above may occur when current volume setting of the hearing instrument and rotational position of the volume control do not match. Therefore, the method is advantageously applicable in particular in a hearing instrument with adjustable by volume remote control volume setting.
  • Another basic idea of the invention consists in a hearing instrument having a signal processing device with a volume adjustment dependent gain, with a receiver, and with a manually operable volume control, which is designed as a dial, in which each rotational position an associated volume setting is permanently assigned.
  • the signal processing device and the rotary control are designed to carry out the advantageous method explained above.
  • the hearing instrument has an RC receiver for control commands of a remote control.
  • the control commands include commands for adjusting the volume setting.
  • the signal processing device, the rotary controller and the RC receiver are designed to carry out the advantageous method explained above.
  • FIG. 1 is a method based on the rotational positions explained in more detail.
  • the method is adapted to be carried out on a hearing instrument with manually operable volume control, which is designed as a knob, and in which each rotational position is assigned a volume setting fixed.
  • step S1 a change in the rotational position of the rotary control is detected.
  • a change sets the process in motion or triggers the procedure.
  • the procedure for hearing instruments with variable by remote control volume only needs to be triggered by manual operation of the rotary control. Therefore, it is just triggered by changing the rotational position of the knob and not by changing the current volume setting of the hearing instrument.
  • a current knob of the rotary knob is determined.
  • the instantaneous rotational position can be determined on the basis of the respectively assigned volume setting. It is also possible to directly determine the rotational position on the basis of the characteristic of an output signal of the rotary control (for rotary potentiometers, for example, a resistance dependent on the rotational position, for optical rotary controls a code designating the respective rotary position).
  • a comparison of the determined instantaneous rotational position is made with a comparison rotational position.
  • the comparison rotational position can be fixed in principle. For example, can be preset as the comparison rotational position that rotational position, which is assigned a minimum volume setting. It may also be a comparison rotational position be given, which is assigned a not minimal, but low volume setting. Another particularly advantageous possibility is that the relevant current volume setting of the hearing instrument is used as the comparison value. The latter option is particularly advantageous because an adjustment of the volume control always takes effect only when the current volume setting is set as a starting point. This volume jumps are completely prevented.
  • step S1 If the comparison reveals that the comparison rotational position has not been reached, the method starts again at step S1. On the other hand, if the comparison indicates that the comparison rotational position has been reached, a change in the volume setting corresponding to the change in the rotational position of the volume control is made in step S4, more precisely depending on the change since reaching the comparison rotational position.
  • step S10 the volume setting assigned to the respective rotary position of the rotary control used subsequently is determined.
  • step S11 a change in the volume setting is detected.
  • step S12 a current volume setting of the rotary knob is detected.
  • step S13 a comparison of the determined instantaneous volume setting with a comparison volume setting is made. If the comparison reveals that the comparison volume setting has not been reached, the process starts again at step S10. On the other hand, if the comparison indicates that the comparison volume setting has been reached, a change in the volume setting corresponding to the change of the volume setting on the dial is made in step S14, more specifically, depending on the change since reaching the comparison volume setting.
  • a hearing instrument 20 is shown schematically which is suitable for carrying out the methods explained above.
  • the hearing instrument 20 has a signal processing device 21.
  • the signal processing device 21 is designed to output an output signal to a receiver 22 whose gain is determined by the volume setting of the hearing instrument 20 is dependent.
  • a knob 23 serves as a volume control. Each rotational position of the rotary knob 23 is permanently assigned a volume setting.
  • an RC receiver 24 is provided, via which control commands for adjusting the volume setting can be received by a remote control.
  • the amplification by the signal processing device 21 is dependent both on the output signal of the rotary control 23 and output signals of the RC receiver 24. Adjusting the volume by remote control does not change the rotational position of the rotary knob 23. Therefore, a discrepancy between the rotational position and the current volume setting of the hearing instrument 20 may result, in particular, with changes in the volume setting by remote control.
  • the invention can be summarized as follows:
  • the invention relates to a hearing instrument, for example a hearing aid, which has a mechanical, manually operable volume control and whose volume can also be adjusted by remote control, and a method for adjusting the volume of such a hearing instrument by means of the mechanical, manual volume control.
  • the volume control is designed as a rotary knob with a fixed assignment of the respective rotational position to a respective volume setting. Adjusting by remote control changes the volume setting, but not the position of the rotary control. This results in the problem that the normally fixed assignment of the respective position of the rotary control is no longer given to the respective volume setting.
  • the object of the invention is to avoid such volume jumps. This is done by the following steps: S1 detecting a change in the rotary position of the rotary control, S2 determine a current rotary position of the rotary control during the change, S3 compare the instantaneous rotary position with a comparison rotary position, S4 change the volume setting of the hearing instrument corresponding to the instantaneous rotary position only if the instantaneous rotary position at least temporarily assumes the comparison rotary position Has.
