Definitions

  • the invention relates to a method for the transmission of Sound by means of at least one sound transmission means, which sound signals perceivable by a person delivers.
  • Such methods are used, for example, to: recorded on a microphone or on a sound carrier to transfer recorded music.
  • Sound transmission means a speaker or also a Headphones that emit sound signals so that they are on connect human hearing through the eardrum.
  • Speakers By placing them in rooms or placing them in headphones Speakers will make the eardrum vibrate offset processed by the person's hearing organ become.
  • the incoming sound signals run in detail through the ear canal to the eardrum and move it in vibrations that are transmitted to the ossicles become.
  • the third ankle guides these vibrations through the so-called oval window to the hearing organ.
  • a disadvantage of this method is that the medium and higher frequency sound signals a higher Sound pressure level and thus a much higher one Have volume that is so high in extreme cases that a person's pain threshold is reached or exceeded becomes. This will overload the eardrum which results in long-term hearing damage.
  • EP 0 553 525 A1 discloses a device for Transmission of sound emerges with the sound transmission means in the abdominal or back area of a person are arranged. Especially when arranging the Sound transmission means in the abdominal area, but also in the arrangement in the back area is proportionate high attenuation of the sound in short distances instead because the one located under the sound transmission means Skin, tissues and other parts of the body very good Have damping properties.
  • the invention has for its object a method for the transmission of sound of the generic type to improve that in addition to the medium and higher frequencies Sound signals also low-frequency sound signals technically easy to implement and therefore cost effective and extremely effective especially while avoiding loss of damping can be transferred.
  • This task is done in a transfer procedure of sound of the type described in the opening paragraph of the invention solved in that one in particular for transmission low-frequency sound signals the sound transmission means in the chest area near the sternum Arranges person so that there is a direct sound transmission path from the sound transmission medium to the Eustachia tube to the person's ossicles.
  • the ossicle has the particularly large one Advantage that this causes the eardrum and thus the Tympanic membrane damping can be avoided. That way No damping compensation due to a variable gain or the like for the correct transmission low-frequency sound signals required.
  • the vibrations by arranging the sound transmission means on the breastbone to be transferred to the entire rib cage because that Sternum in connection with and over the ribs again stands with the pleura.
  • the chest brings now again the air in the lungs to vibrate. From there, the vibrations pass through the pharynx to the Eustachi tube and from there to the ossicles.
  • the advantage here is that the entire chest is used as a sound box and so far Bandpass housing, similar to the well-known subwoofer. This results in low-frequency sound signals particularly advantageous bypassing the eardrum transfer.
  • the procedure is simple with technical means realize and requires only a proportionate low energy consumption. It can also be used in one mobile device can be used.
  • the object of the invention is also also still by a device for transmitting sound solved with at least one sound transmission means, at which the at least one sound transmission means in Chest area near a person's sternum is arranged so that there is a direct sound transmission path from the sound transmission medium to the Eustachia tube to the person's ossicles.
  • the one on the sternum in this way sound transmission means arranged to a person transmitted, it is particularly advantageous that the at least one sound transmission means at least one Distribution means is downstream, in which the distribution the sound signals are made.
  • Designs may be provided, advantageously comprises the at least one distribution means however at least one frequency filter means.
  • the frequency filter means With regard to the frequency filter means, the most varied Possible designs.
  • the frequency filter means is a low pass, which is technically particularly easy to implement.
  • the frequency filter means a crossover and a low pass and a high pass include, the medium and passing the high pass higher-frequency sound signals by means of another Sound transmission means are transmitted to which the eardrum emits sound coupling to the person.
  • the inventive method for the transmission of sound can best be explained with reference to FIG. 1. How from 1 shows a signal source 40 sound signals output to a distribution means 50 fed.
  • 50 can be used as distribution means any design can be considered, it could Distribution means 50, for example a frequency filter means or a crossover, which in turn for example by a low pass 20 and a high pass 30 can be realized.
  • Distribution means 50 for example a frequency filter means or a crossover, which in turn for example by a low pass 20 and a high pass 30 can be realized.
  • Higher frequency sound signals are thereby on the eardrum 60 on the auditory organ 80 transmit, whereas low-frequency sound signals transmitted to the hearing organ 80 via the sternum 70 become.
  • the transmission happens, for example through loudspeakers 27, 37, the downstream of the low-pass filter Speaker 27 near the breastbone 70 is arranged, during which the high pass 37 downstream Loudspeaker 37, for example in the form of headphones is trained. It goes without saying that the low-frequency sound signals additionally via the Loudspeaker 37 can
  • An embodiment of a device for transmission of sound shown in Fig. 2, includes sound recording or playback device 10, for example a Cassette player or microphone with one downstream amplifier and the like. Which signals via a signal line 11 to the frequency filter means in Outputs a low pass 20 and a high pass 30.
  • the low pass 20 is designed so that it only sound signals pass below 700 Hz, while medium and higher frequency sound signals over 700 Hz filtered out of the low-pass filter 20 from the sound signals become.
  • the high pass 30 pass only medium and / or higher frequency sound signals above 700 Hz while Sound signals below 700 Hz in the high pass 30 from the Sound signals are filtered out.
  • the low pass 20 and the high pass 30 can still each amplifiers designed for the corresponding frequencies 25, 35, which sound transmission means control in the form of speakers 27, 37.
  • the speaker 27 is - as mentioned above - in Chest area near a person's sternum 70 arranged so that there is a direct sound transmission path from loudspeaker 27 over the rib cage, the eustachia tube, towards the person's ossicles results.
  • the person's chest cavity acts as additional sound box, similar to that for the Transmission of low-frequency sound signals from audio technology known subwoofers.
  • the loudspeaker 37 can be one in itself, for example known loudspeaker box, or - as above also already mentioned - be a headphone or the like, the one Sound coupling via a person's eardrum 60 enables.
  • Such a device is simple technical Means to realize. It is light, compact and transportable and is therefore everywhere and at any time usable, in particular it can also be used as a mobile device - Similar to the known cassette or compact disc players - be carried out. Beyond consumed it only has a little energy and can also be used Batteries are fed as an energy source, making them is independent of external energy sources. Finally it is also special for the reasons mentioned above inexpensive to manufacture and therefore also for To buy end consumers inexpensively.
