Siemens’ MUSIC is a complete line of hearing aids that is now enjoying worldwide success. With MUSIC, Siemens developers were able to set new standards in speech intelligibility. These hearing aids automatically adjust to the volume of ambient noise, based on a principle of two-channel technology with compression systems operating independently of one another.

With PRISMA, the first fully digital hearing instrument, Siemens set new international standards for digital hearing aids. In addition to all-round hearing, the TwinMic™ multi-microphone system also permits the selection of directional hearing focused in front of the wearer, which makes speech more intelligible even in group situations or other noisy environments. And with “speech-sensitive signal processing”, PRISMA reduces ambient noise even further.

The TCI (Tinnitus Control Instrument) combines the latest scientific findings on tinnitus with the latest hearing aid technology. In a clinical study conducted by the Bad Meinberg Tinnitus Research Group, TCI fulfilled the highest expectations: It brought noticeable relief to 90% of patients suffering from severe tinnitus. TCI can also be combined with digital hearing instruments. For the first time ever, hearing-impaired tinnitus patients have access to state-of-the-art digital hearing aid technology. This means that the hearing impaired can also continue to use their hearing instrument when they no longer suffer from tinnitus.

SIGNIA is the first hearing instrument specifically designed to improve the acoustical contrast between speech and environmental noise for optimal speech intelligibility. TwinMic, the selectable directional microphone system incorporating the latest developments, clearly accentuates speech against background noise in precisely the direction of the wearer’s gaze. SIGNIA is also safeguarded against high-frequency energy to prevent problems with the use of cordless or cellular phones. And for children, SIGNIA is available in a “mouse design.” With the introduction of Signia S in 2001, Siemens offered a hearing instrument that met the highest acoustic requirements and set new standards in terms of design and wearing comfort.

With TRIANO, Siemens launched a new generation of hearing instruments that offers the right solution to almost any individual hearing problem. TRIANO 3 is the first hearing aid in the world to combine three microphones in a system known as TriMic™. A special signal processing system in TRIANO automatically enhances the spoken word and suppresses background noise. The fully developed directional microphone technology in which two or even three microphones work together provides optimal speech intelligibility even in noisy surroundings. TRIANO, the speech comfort system, automatically recognizes the most important sounds and rapidly adapts to the situation, even when the source of noise is moving. And thanks to soft fading, the adjustments are so smooth that the wearer hardly notices the transition.

PRISMA 2K is a hearing instrument specially designed for young babies with hearing impairment. Support at an early stage is particularly important if infants are to have the opportunity to develop their language skills properly. PRISMA 2K meets the special needs for a hearing instrument for babies, because it is extremely small, flexible and reliable. This device was developed in close cooperation with experts from pediatric audiology departments, ear, nose and throat clinics, and the Academy for Hearing Aid Acoustics.

ACURIS provides the ideal solution for all people with binaural hearing loss, and restores the benefits of being able to hear properly in both ears. Its synchronized mode of operation means that ACURIS can provide better sound quality and user comfort, as well as being easier to use and more discrete than conventional hearing instruments. The two hearing instruments communicate by means of the integrated e2e (ear-to-ear)™ wireless technology, the smallest radio system in the world. Control signals are exchanged between the left and right hearing instrument, and on the basis of this information the hearing system carries out synchronized adjustments to each hearing instrument independently, as well as selecting the microphone mode, and the speech and background noise management appropriate for the current acoustic situation.

With iScan™ a new technology enters the acoustician’s office. Thanks to iScan it is now possible to scan ear impressions directly at the acoustician’s workplace. All data which is necessary for the order of an in-the-ear hearing system can be sent electronically to our production facilities. Endconsumer benefits include: The digital ear impression will not be damaged during transit nor be affected by temperature changes (extreme heat or cold). In case of damage or loss of an in-the-ear system the scanned ear impression can be reused – thus the customer need not have an ear impression taken again. Internal studies show that in-the-ear systems produced with iScan data have a better fit than conventionally produced instruments. The delivery time for in-the-ear systems is reduced.

With CENTRA, Siemens developed a new family of hearing aids setting a new standard in hearing comfort. Thanks to "SoundSmoothing", "Data Learning", and "e2e" technology, these innovative instruments use technology that remembers volume preferences for each individual listening program, recognizes and reduces impulsive noises, and keeps both instruments properly balanced at all times.

With CENTRA Active, Siemens focuses attention on needs of the “active,” senior generation, a demographic segment increasing worldwide. Building upon innovative technology already in CENTRA, the new instrument placed its receiver within the ear canal. The so-called receiver-in-the-canal (RIC) allows for cosmetically pleasing small and light models.
