Definitions

  • the present invention relates to a hearing device, in particular a hearing aid, with a sound output device for sonicating a user's hearing. Moreover, the present invention relates to a method for determining a room acoustics.
  • a hearing aid with adaptive adaptation of microphones with a phase compensation circuit is known.
  • the phase compensation is based on test sound, which is generated in a spatially determined test sound source.
  • DE 101 38 949 A1 a method and an acoustic system for influencing surround sound. It should be noted that a test signal with a known frequency response can be recorded with a measuring microphone at various positions in the direct sound field.
  • the object of the present invention is therefore to provide a hearing device with which information about a current room acoustics can be determined.
  • a corresponding method for determining information about the room acoustics is to be provided.
  • this object is achieved by a hearing device, in particular a hearing device, having a first sound output device for sonicating a user, a second sound output device, which differs from the first sound output device, for outputting a test sound into a room in which the hearing device is located , and a receiving device for receiving a response to the test sound from the room.
  • the invention provides a method for determining information about a room acoustics, by outputting a test sound by a hearing device, in particular a hearing device, into a room in which the hearing device is located, receiving a response to the test sound from the room by the hearing device and determining the information about the room acoustics from the answer.
  • information about the room acoustics can thus be obtained by the hearing device. This can then be further processed internally or externally.
  • the hearing device according to the invention has a signal generator for generating a test sound.
  • the test sound does not have to be generated via the usual signal processing device that is present in each hearing device, so that processing capacity can be saved.
  • the signal generator can be used together with the signal processing device of the hearing device on a single electronic chip be arranged. This reduces the production costs for electronics of the entire hearing device.
  • the test sound is generated in the ultrasonic range. This has the advantage that for measuring the room acoustics no audible sound is used, which can be perceived by the user of the hearing device or the hearing aid wearer.
  • the second sound output device of the hearing device according to the invention may have a membrane speaker.
  • a standard component element can be used to generate the test sound.
  • the hearing device may further comprise an analysis device for determining a room acoustics or a corresponding room acoustics information as a function of the response received in the reception device.
  • This room acoustics information can be used internally or transmitted to the outside.
  • the signal processing device of the hearing device can be adjustable by the analysis device in accordance with the determined room acoustics information.
  • the signal processing can be better adapted to the current acoustic situation for the hearing impaired.
  • the illustrated hearing aid HG has a signal generator and signal analyzer GA on.
  • a loudspeaker LS is connected, which is arranged on the surface of the hearing aid housing GH.
  • the signal generator GA and the loudspeaker LS thus represent an acoustic signal transmitter, which is installed in the hearing aid or its housing GH and for dispensing an acoustic test signal, for. B. in the ultrasonic range, is suitable.
  • the sound emitted by the loudspeaker LS reflects on the walls and objects of a room and thus transforms into a room response which can be recorded by a microphone M of the hearing aid HG.
  • This microphone M may be a conventional hearing aid microphone, but also a microphone provided specifically for recording room responses for determining the room acoustics.
  • the recorded spatial response is electrically converted in the microphone M and sent to the signal generator and analyzer GA. There it is examined in terms of room acoustics peculiarities, for example, whether the room is very echoing. The analysis then leads to room acoustics information, with which different room acoustics can be divided into different classes.
  • the hearing aid-internal signal processing SV is activated. This means that the signal processing algorithm is set according to the room acoustics. Consequently, the signal processing in the hearing aid HG is optimized for the current room acoustics. This increases the quality of the automatic adjustment of the hearing aid.
  • the acquisition of the room acoustics information and an automatic adaptation based thereon can be used not only for hearing aids, but also for other hearing devices such as headsets, headphones and the like.
