(54) Fors tærkerarrangement til brug ved undervisning af personer med nedsat hørelse.(54) Provide a thinner arrangement for use in the training of hearing impaired persons.

Opfindelsen angår et forstærkerarrangement til brug ved undervisning af personer med nedsat hørelse for at forstærke mikrofonsignaler og for at afgive signaler til en hovedtelefon, hvilket arrangement omfatter indstillingselementer for tilpasning af de akustiske karakteristika, såsom kompression, frekvenskarakteristik osv., til brugeren. Et forstærkerarrangement af denne art kendes f.eks. fra gg tysk fremlæggelsesskrift nr. 12 83 904. Et sådant forstærkerarrange- ment er permanent indbygget i en elevs pult for den elev, hvis hø-relse er forringet. Indstillingselementerne tjener til individuelt no at tilpasse de akustiske egenskaber af forstærkerarrangementet til den ved den pågældende pult anbragte elevs hørefejl.The invention relates to an amplifier arrangement for use in teaching persons with hearing impairment to amplify microphone signals and to output signals to a headphone, which arrangement includes setting elements for adapting the acoustic characteristics such as compression, frequency characteristics, etc., to the user. An amplifier arrangement of this kind is known e.g. from gg German Petition No. 12 83 904. Such an amplifier arrangement is permanently built into a student's desk for the student whose hearing is impaired. The adjusting elements serve to individually adapt the acoustic characteristics of the amplifier arrangement to the hearing error of the student in question.

Tilpasning af forstærkerarrangementet til elevens hørefejl, *Adaptation of the amplifier arrangement to the pupil's hearing defects, *

QQ

2 143777 hvilket kun kan foretages af eksperter, kræver megen tid,og når forstærkerarrangementet på en bestemt elevs plads først er tilpasset elevens hørefejl, vil eleven altid benytte samme pult. Udveksling af elevpulte inden for samme klasse af personer med nedsat hørelse eller flytning til en pult i en anden klasse kan derfor ikke praktiseres.2 143777 which can only be done by experts requires a lot of time, and when the amplifier arrangement in a particular student's room is first adapted to the pupil's hearing errors, the pupil will always use the same desk. Therefore, the exchange of student desks within the same class of persons with hearing impairment or relocation to a desk in another class cannot be practiced.

Opfindelsen går ud på at tilvejebringe et forstærkerarrangement, som ikke har denne begrænsning. Dette opnås med et forstærkerarrangement af den indledningsvis angivne art, der ifølge opfindelsen er ejendommelig ved, at indstillingselementerne er anbragt i en særskilt indstikningsenhed, der ved hjælp af en stikforbindelse kan forbindes til forstærkersektionen. Herved hører indstillingsorganerne ikke længere til forstærkeren eller til elevpulten, hvori forstærkeren indgår, og som ellers bandt den person, hvis hørelse er nedsat, til altid at benytte samme pult eller samme klasseværelse.The invention is to provide an amplifier arrangement which does not have this limitation. This is achieved with an amplifier arrangement of the type indicated in the introduction, which is characterized by the fact that the adjusting elements are arranged in a separate plug-in unit which can be connected to the amplifier section by means of a plug connection. As a result, the adjusting organs no longer belong to the amplifier or to the student desk in which the amplifier is included, and which otherwise tied the person whose hearing is impaired to always use the same desk or classroom.

I stedet for kan hver elev nu have sin egen indstikningsenhed, som rummer indstillingselementerne tilpasset efter elevens personlige hørefejl. Når eleven skifter plads, skal han blot fjerne indstikningsenheden fra forstærkeren og indsætte enheden i den anden pults forstærker. Et krav er, at alle forstærkersektionerne i elevpultene har samme konstruktion.Instead, each student can now have his or her own insertion unit, which contains the setting elements adapted to the student's personal hearing defects. When the student switches space, simply remove the insertion unit from the amplifier and insert the unit into the other desk amplifier. One requirement is that all the amplifier sections in the student desks have the same construction.

Opfindelsen muliggør, at den individuelle tilpasning af indstillingsorganerne til en dårligt hørende persons hørefejl kan udføres af en audiolog ved hjælp af et audiometer, der indeholder en forstærker af samme konstruktion som forstærkerne, der findes i e-levpultene. Desuden kan hvert indstillingselement, som f.eks. kan udgøres af et potentiometer, være forsynet med tal, der angiver indstillingen af dette indstillingselement. Hvis disse tal for de forskellige indstillingselementer er arrangeret i en vis rækkefølge, fås et identifikationsnummer for personen med nedsat hørelse.The invention allows the individual adaptation of the adjusting means to a hearing impaired person's hearing errors to be performed by an audiologist by means of an audiometer containing an amplifier of the same construction as the amplifiers found in the e-life terminals. In addition, each setting element, such as may be constituted by a potentiometer, be provided with numbers indicating the setting of this setting element. If these numbers for the various setting elements are arranged in a certain order, an identification number for the hearing impaired person is obtained.

Det kan ske, at de akustiske egenskaber af hovedtelefonerne afviger så meget, at tilpasningen ved passende indstilling af ind-stillingselementerne i afhængighed af en dårligt hørende persons hørefejl kun kan ske i forbindelse med en speciel hovedtelefon. I dette tilfælde kan indstikningsenheden ifølge en udførelsesform for opfindelsen være således uudløseligt forbundet med hovedtelefonen, at den tjener som forbindelsesdel for hovedtelefonen til forstærkersektionen. Herved opnås, at indstikningsenheden med indstillingselementerne og hovedtelefonforbindelsen udgør en konstruktiv enhed. Indstikningsenheden forbliver så forbundet med den hovedtelefon, hvor 143777 3 med tilpasningen til hørefejlen er foretaget. Følgelig medbringer eleven, når denne skifter plads, hovedtelefonen sammen med indstikningsdelen, der udgør hovedtelefonforbindelsen, til den næste pult.It may happen that the acoustic properties of the headphones differ so much that, by appropriately adjusting the adjusting elements, depending on the hearing impairment of a hearing impaired person, adaptation can only be made in connection with a particular headphone. In this case, the plug-in unit according to one embodiment of the invention may be so inextricably connected to the headphone that it serves as the connecting part of the headphone to the amplifier section. Hereby, the insertion unit with the setting elements and the headphone connection is obtained as a constructive unit. The plug-in unit then remains connected to the headset where the adaptation to the hearing error is made. Accordingly, when this space changes, the student brings the headphone along with the plug-in part that makes up the headphone connection to the next desk.

Opfindelsen forklares nærmere i forbindelse med en udførelsesform under henvisning til den skematiske tegning, hvor fig. 1 viser et blokdiagram over et forstærkerarrangement med indstillingselementer, som er nødvendige for tilpasning til en høre-fejl, fig. 2 et panel med trykt kredsløb, hvorpå indstillingselementerne er monteret, fig. 3 indstikningsenheden, der indeholder det trykte kredsløbspanel, og fig. 4 et forstærkerarrangement med en sådan indstikningsenhed.The invention is further explained in connection with an embodiment with reference to the schematic drawing, in which fig. 1 is a block diagram of an amplifier arrangement with adjusting elements necessary for adaptation to a hearing error; FIG. 2 shows a printed circuit board on which the setting elements are mounted; FIG. 3 shows the insertion unit containing the printed circuit board; and FIG. 4 shows an amplifier arrangement with such a plug-in unit.

Fig. 1 viser et forstærkerarrangement 1, der kan indgå i en elevs pult. Forstærkerarrangementet, som er tilpasset til stereogengivelse, omfatter to ens kanaler, der hver har en forforstærker 2 og 3, hvortil et mikrofonsignal føres. Udgangene fra forforstærkerne 2 og 3 er forbundet til indgangene i hver sin udgangsforstærker 4 og 5, til hvis udgange en hovedtelefon kan forbindes. Indstillingselementer i form af potentiometre 11-15 og 21-25 er forbundet til hver af forstærkerkanalerne, hvilke potentiometre tjener til individuel indstilling af styrke, spidsklipningsniveau, bas og diskant samt automatisk forstærkningsstyring for hver af de to kanaler. Sådanne forstærkerarrangementer med to kanaler kendes, hvorfor kredsløbsopbygningen ikke behøver at beskrives nærmere. Det er blot væsentligt, at indstillingselementerne 11-15 og 21-25, som angivet med blokken 6, er anbragt i en indstikningsenhed, som ved udkobling fra den øvrige del af forstærkerarrangementet kan adskilles i fysisk henseende fra denne. Potentiometrene 11-25 er monteret på et trykt kredsløbspanel 9, jvf. fig. 2, og er elektrisk forbundet til en kontaktrække 7 ved den ene ende af panelet.FIG. 1 shows an amplifier arrangement 1 that can be included in a student's desk. The amplifier arrangement, adapted for stereo reproduction, comprises two identical channels, each having a preamplifier 2 and 3 to which a microphone signal is applied. The outputs of the preamps 2 and 3 are connected to the inputs of each of the output amplifiers 4 and 5, to whose outputs a headphone can be connected. Adjustment elements in the form of potentiometers 11-15 and 21-25 are connected to each of the amplifier channels, which potentiometers serve to individually adjust the strength, peak cutting level, bass and treble as well as automatic gain control for each of the two channels. Such two-channel amplifier arrangements are known, so the circuit structure does not need to be further described. It is only essential that the setting elements 11-15 and 21-25, as indicated by the block 6, are arranged in a plug-in unit which can be physically separated from the other part of the amplifier arrangement by switching off. The potentiometers 11-25 are mounted on a printed circuit board 9, cf. 2, and is electrically connected to a contact line 7 at one end of the panel.

Det trykte kredsløbspanel kan anbringes i et hus 8, som vist i fig. 3, hvilket hus har åbninger, hvorigennem giidearmene i poten-tionetrene 11-25 kan indstilles, hvilket hus kan være mærket med navn og de identifikationstal, der er omtalt i indledningen, og som kendetegner indstillingen af de enkelte indstillingselementer og derfor hørefejlen for brugeren af indstikningsenheden.Indstillingselementerne 11-25 kan forbindes elektrisk til forforstærkere og udgangsforstærkere 2-5 ved indstikning af kontaktrækken 7, der rager frem fra huset 8 i en tilsvarende bøsningrække, som findes iThe printed circuit board can be placed in a housing 8, as shown in FIG. 3, which housing has openings through which the guide arms of the potentiometers 11-25 can be adjusted, which housing can be labeled with the names and identification numbers mentioned in the introduction, which characterize the setting of the individual setting elements and therefore the hearing error for the user of The adjusting elements 11-25 can be electrically connected to preamplifiers and output amplifiers 2-5 by inserting the contact pull 7 which protrudes from the housing 8 into a corresponding socket row contained in
