Description
division explanation
The application belongs to the divisional application that the applying date is the Chinese invention patent application 200780047241.X on December 18th, 2007.
Technical field
The present invention relates to the hearing device of such as hearing aids or implantable hearing prosthesis, it has user interface, is provided for user and can provides feedback to hearing device.
Background technology
Known in the field of hearing aids have multiple modes of operation.Described different operator scheme makes hearing aids can meet the various general and/or specific needs of the user under different situations or environment as well as possible.As an example, directionality make hearing aids likely " focusing " be positioned at such as hearing aids wearer front portion, in the sound source of such as talker.Thus, the possible interference sound from wearer side and the back side has limited impact by for the perception of wearer on the sound in the source from his/her front portion.Therefore one or more operator scheme may comprise such beamforming signal transacting.
As another example, a kind of specific acoustic environment may require to use specific noise suppressed and/or other specific signal transacting, and it is therefore, it is possible to be selected as operation sequence or pattern.And in one or more operator scheme, hearing aids can use induction coil (telecoil) for receiving the audio-frequency information from electromagnetic field.
Because hearing impaired people is according to his/her needs, manual switchover is very inconvenient between different modes of operation, therefore several trial has been taken to develop effective method, for automatically selecting the operator scheme of " the best " when listening to environment or condition changes.
Modern hearing aids has characteristic signal process, described characteristic signal process or be automatically adjusted based on the feedback signal according to the setting of programming in advance, or automatically adjusted by continuous print, the adjustment that increases progressively, described continuous print, the adjustment increased progressively are considered to the intelligibility of the voice improved under given environment or listen to comfort level.Frequently, be used in so-called " soft handover " between pattern or state, not produce change that is unexpected and interference in sound quality.
And many hearing aidss provide for hearing aids being forced according to the selection of user the chance entered in certain pattern.Signal is added in the audio signal of amplification, with the change of affirmation mode.Described signal is series of beeps etc. normally.Advised that such signal can be the record of speech message in the past.
One of hidden danger of the automatic switchover of pattern is that described systematic evaluation is to not seen the pattern or state that make improvements by user.Not every user has identical requirement when it seems similar with recognition system, and can not find this point during adaptation processing.
