Abstract

SE PRESENTA UN SISTEMA DE REPRODUCCION DE SONIDOS MULTIDIMENSIONAL PARA LA RECEPCION DE UNA GRABACION BIAURICULAR O DE CUALQUIER OTRO TIPO PRODUCIDA DE MANERA CORRECTA EN UNOS CANALES IZQUIERDO Y DERECHO Y EMITIR LA GRABACION A UNOS ALTAVOCES LOCALIZADOS (58) Y (60). LOS ALTAVOCES LOCALIZADOS (58) Y (60) SE ENCUENTRAN SOPORTADOS EN UN PAR DE LENTES (70) QUE SE ENCUENTRAN EN UNOS RECEPTACULOS (80) Y (82). CADA UNO DE LOS ALTAVOCES (58) Y (60) SE ENCUENTRAN DIRIGIDOS POR LA PARTE DE ATRAS HACIA EL PABELLON (68) DE LA OREJA IZQUIERDA Y DERECHA ASOCIADO DEL INDIVIDUO Y SE ENCUENTRAN CERCA DEL ARCO CIGOMATICO DEL OYENTE (26). DE ESTE MODO, LOS ALTAVOCES LOCALIZADOS (58) Y (60) QUEDAN SEPARADOS DE LAS OREJAS OPUESTAS DEL OYENTE (26) PARA NO PERTURBAR LA RESONANCIA DE CONCHA EN LA UNICA RESPUESTA DEL PABELLON DE LA OREJA DEL OYENTE. EL FINAL DE BAJA FRECUENCIA DEL ESPECTRO DE FRECUENCIAS DE LA GRABACION BIAURICULAR SE FILTRA DESDE LA ENTRADA DE LOS ALTAVOCES LOCALIZADOS (58) Y (60), SE SUMAN Y DESPUES SE SACAN POR UN ALTAVOZ EXTERNO (52). SE PROPORCIONA UN PANEL DE VISUALIZACION (64) PARA QUE EL OYENTE (26) PUEDA VER UNA SERIE DE INDICACIONES QUE LE AYUDAN A LOCALIZAR EL SONIDO.A MULTIDIMENSIONAL SOUND REPRODUCTION SYSTEM IS PRESENTED FOR THE RECEPTION OF A BIAURICULAR RECORDING OR ANY OTHER KIND PRODUCED CORRECTLY IN SOME LEFT AND RIGHT CHANNELS AND EMIT THE RECORDING TO SOME LOCATED SPEAKERS (58) (58) THE LOCATED SPEAKERS (58) AND (60) ARE FOUND IN A PAIR OF LENSES (70) WHICH ARE LOCATED IN SOME RECEPTACLES (80) AND (82). EACH OF THE SPEAKERS (58) AND (60) ARE DIRECTED BY THE BACK PART TO THE PAVILION (68) OF THE LEFT AND RIGHT EAR ASSOCIATED WITH THE INDIVIDUAL AND ARE NEAR THE ZYGOMATIC ARC OF THE LISTENER (26) IN THIS WAY, THE LOCATED SPEAKERS (58) AND (60) ARE SEPARATED FROM THE OPPOSING EARS OF THE LISTENER (26) IN ORDER NOT TO DISTURB THE CONCHA RESONANCE IN THE ONLY RESPONSE OF THE PAVILION OF THE LISTENING EAR. THE LOW-FREQUENCY END OF THE FREQUENCY SPECTRUM OF THE BIAURICULAR RECORDING IS FILTERED FROM THE ENTRANCE OF THE LOCATED SPEAKERS (58) AND (60), ADDED AND THEN REMOVED BY AN EXTERNAL SPEAKER (52). A DISPLAY PANEL (64) IS PROVIDED SO THAT THE LISTENER (26) CAN SEE A SERIES OF INDICATIONS THAT HELP YOU LOCATE THE SOUND.
