5 Un sistema FM inalámbrico consiste de dos componentes básicos

6 Los desafíos de la comunicación en ambientes escolares
Limitaciones de los audífonos Ambiente Desarrollo del lenguage Understanding the barriers that children face is central to creating solutions and evaluating the results. Why we are focusing on the school? Children spend much of their day in school. There are many challenges to overcome in this setting. Hearing aids still have limitations. The hearing loss distorts and limits sound processing and this is further complicated by the fact that the Hearing-impaired child has limited prior EXPERIENCE of hearing and language as a point of reference. Even hearing instruments with the most advanced technology that are adjusted properly to the user’s needs cannot guarantee an adequate signal-to-noise ratio in all situations. The environment may be a barrier:Schools present many challenges and can introduce barriers for hearing and communication. For example, important instructional activities frequently occur in the presence of high noise and distractions. Many classrooms have poor acoustics, exacerbating the problem. Overcoming these barriers is essential, as the school is central to learning and socialization. Language development is less advanced: Children with hearing loss are often less advanced in their language development. They need all the help they can get to make the right advances at an early age and to retain that advantage throughout childhood and into adulthood. Access to technology is essential: Information technology is a central part of the school curriculum. All children need access to the key learning tools. Compatibility of equipment is a further challenge for children with hearing loss, as they must have access to equipment that works well with their hearing instruments. In considering solutions for school programs, it is important challenges are overcome without creating any new problems of equipment incompatibility. In addressing each of these concerns, it is essential that the child’s practical needs are central to all decisions and solutions. Acceso a la tecnología

12 TRANSMISOR - Campus S Tecnología sintetizada
Sincronización directa de las frecuencias Campus S is Phonak’s multi-frequency transmitter. Its synthesizer technology means that it can carry a large range of channels. At the mere touch of a button, through direct frequency synchronization, it can set or reset the frequency of any multi-frequency receiver in its vicinity. This makes it an extremely flexible and versatile unit for school settings.

13 Campus S : características
Fácil selección de canales Rápida sincronización con el toque de un botón Visualización LCD Bloqueador de teclas Práctica visualización del consumo de la pila The on-off switch turns on the Campus S. It “remembers” its last position. This is ideal for most applications, as teachers will usually be transmitting on the same assigned classroom channel day after day. Channel selection is simple and easy. The active channel can be switched to accommodate individual teaching situations or movement between classrooms. Change the channel by pushing the up or down arrow. Quick synchronization at the touch of a button. Synchronize by pushing the Synchronization key to transmit this new channel to receivers in the vicinity. Observe the number change on the LCD. The clear display provides verification that you are on the correct channel. The locking feature is activated and deactivated by simultaneously pressing the lower keys. The figure symbol in the display indicates locked status. Locking is a convenience feature to ensure that the transmission frequency remains active and doesn’t slip inadvertently due to random movement The practical battery status indicator enables monitoring of the reserve power status.

14 Campus S Versátil interfase audio para la: Pila recargable
TV PC Videograbadora CD Pila recargable Conexión del micrófono (oculta) Cable del micrófono cubierto The Campus S transmitter is equipped with an audio jack, so that it can be connected to a television, personal computer, video recorder or CD player. The microphone remains active for voice annotations during use of this versatile audio interface. The audio jack is also used for channel programming, making the unit even simpler to operate. The integrated rechargeable battery (NiMH) of Campus S can be conveniently recharged via a power supply unit. In addition, a depleted battery can be removed and replaced with a fresh one. Thanks to the recharging unit for multiple batteries, the Campus S can be operated permanently without interruption. A freshly recharged battery will provide Campus S with continuous power for about 12 hours of operation. The microphone jack is the Campus S’s port for live voice input. The microphone is for direct communication by a teacher, parent, tutor, or anyone conversing with the hearing-impaired listener. The microphone jack is hidden behind the clip for protection. Built-in cord storage permits the cord and microphone to be tucked away from sight and protected against damage.

15 Estándarización Compatibilidad universal sin comprometer su funcionamiento y calidad Se puede utilizar con cualquier combinación de receptores y transmisores Se puede utilizar con cualquier combinación de sistemas FM y audífonos Se ajusta rápidamente a nuevas situaciones Brinda acceso a la mejor tecnología independientemente del ambiente escolar Permite un fácil movimiento y compenetración de los estudiantes Ofrece una solución flexible para escuelas S is for Standardization. Phonak stands for universal compatibility without compromise of function or quality. All equipment is standardized to allow any combination of receivers and transmitters, and any combination of hearing aids and FM systems. Phonak has set the standard with hearing instrument manufacturers, so that nearly all manufacturers developing new products are explicitly careful in ensuring their units are compatible with Phonak technology. The benefits are significant for all. Children can quickly adapt to new situations. Regardless of school placement, whether mainstreamed or in self-contained classrooms, they have access to the best technology. For schools, and school systems, it is easy for them to plan for inclusion and movement of students around the school. Standardization also implies improved cost management for such issues as training and equipment rotation etc.

16 Éxito asegurado–en cualquier ambiente escolar
Tecnología multi-frecuencia única y exclusiva Fácil cambio de las frecuencias Comunicación sin barreras Acoplamiento transparente y consistente entre el audífono y la señal acústica en FM Funcionamiento automático y transición transparente S most importantly is for Success – for the child… (the one who uses it). Our breakthrough Multi-frequency technology is made to work well and easily. Because channels change automatically from the child’s perspective, he or she doesn’t worry about anything and communicates spontaneously from one environment to the next. Multi-frequency Microlink technology carefully matches the FM to the student’s own hearing aid settings. Phonak allows no compromise in ensuring that the signal received is true and clear. All of these features combine to give the user an automatic and seamless listening experience.

17 MLxS y los procesadores de los implantes cocleares
Una mejor relación-señal-ruido (RSR) Un mejor rendimiento en presencia de ruido Pequeños y livianos La programacion FM se puede ajustar para distintos “Mapas” de programación del procesador Users of cochlear implants are frequently confronted with hearing situations that make it difficult to understand speech. MicroLink CI S clearly enhances speech intelligibility in these environments and is vital to a CI user’s comprehension in a noisy classroom. The state-of-the-art microchip has an improved signal to noise ratio and performs even better in noise, significantly improving the ability of the CI user to communicate. It is small, lightweight and unobtrusive. As with MLxS and ML8S, the unit can be adjusted to suit the varied needs of cochlear implant users, such as might be needed for different MAPS. All of this makes Phonak FM the new standard for cochlear implant users. For all body worn processors, there is a Microlink CI adaptor with a standard euro connector to accommodate the MLxS. The MLxS fits to the ear-level implant, the ESPrit 3G, by means of Cochlear’s shoe-like adaptor for a discreet and comfortable fit.

21 Todos los productos FM de Phonak son compatibles
MicroLink CI S TelCom All Phonak FM products are compatible. Here are some examples. All Phonak transmitters work well with all Phonak receivers. Thus, the single frequency transmitters (the HandyMic and the MicroVox (not pictured), will also transmit to multi-frequency receivers. The multi-frequency Campus S will also transmit to single frequency receivers. The TelCom works with all receivers to provide flexible access to television, telephone and computer. Here we also show the SmartLink, the new multi-frequency transmitter of the future. SmartLink will also work with MLxS and ML8 S to provide: FM transmission, Bluetooth connection to cell phone; and remote control. The only requirement is that both the transmitter and the receiver use the same frequency channel. We also picture the MicroLink CI S adaptor and the MLxS BAHA, which work with Cochlear implant and BAHA devices, respectively. In order to have the benefit of multi-frequency functions, both the transmitter and the receiver must have S (synthesizer) technology. However, there are many situations where the single frequency mode is all that is needed. For example, a child may use the MLxS with the Campus S systems at school, and with the HandyMic and TelCom at home. Phonak is dedicated to maintaining this important compatibility with all future products. TIP: Note the option to use this slide as a product overview in a shorter presentation.
