New Siemens hearing aid provides top performance in mini-housing


Nuremberg / Erlangen, Germany - Siemens presented its powerful, but small behind-the-ear hearing aid, “Pure Carat”, at the 56th International Hearing Aid Acoustician Congress 2011 (EUHA) in Nuremberg. Like all “Pure” hearing systems, it’s no larger than your fingertip and weighs just two grams. The new device - top of its product family - is particularly suited for those who are profoundly hard of hearing. A newly developed high-performance receiver, capable of amplifying sound and speech of a volume of up to 130 decibels, sits directly in the ear canal. At the same time, the smaller BTE housing provides more room for a larger battery capable of providing the device with the required power.

Siemens’ “Pure” hearing systems are receiver-in-canal (RIC) devices, which use a receiver in the ear canal connected to the device by a small, virtually invisible tube. As a result, the BTE housing is extra small and discreet. And since it is just the receiver and not the entire device that sits in the ear, the sound is much more natural.

Until now, RIC hearing systems could only compensate for mild to profound hearing loss, since conventional receivers vibrate from strong amplification. And the size of battery required for greater amplification puts a limit on what designers and developers can do with it. But now Siemens’ “Pure Carat” provides maximum performance with minimal size. Although the BTE housing discreetly tucks behind the ear, it still offers enough room for a high-performance battery. With a rechargeable battery, the “Pure Carat” can be recharged overnight with a supplementary “eCharger” – saving money and the environment – without having to remove the batteries from the hearing aid in the process.

In addition, Siemens developed a new kind of RIC receiver that is produced for each individual ear, similar to the in-the-ear hearing device. That way the receiver remains securely in the ear and allows for a high feedback-free amplification of speech and sound of up to 75 decibels to a maximum volume of 130 decibels. By way of comparison, not even the loudest rock bands play at a volume of 130 decibels. Yet that is the volume sometimes necessary to compensate for profound hearing loss.

Along with its discreet design and high performance level, the “Pure Carat” wins customers over with a comfortable listening experience thanks to “BestSound Technology” developed by Siemens: Even when the gain is at its maximum, the “FeedbackStopper” reliably prevents annoying feedback ’whine’; “SpeechFocus” recognizes the direction of a speaker and switches to the most suitable microphone mode; And “SoundLearning 2.0” memorizes the wearer’s preferred settings for various hearing conditions and then automatically switches to the respective mode.

In addition, a telephone coil is integrated into the “Pure Carat”, which receives the signal from induction loop systems in churches, cinemas and theaters. With the optional, multi-functional remote control, “Tek” or “miniTek”, the hearing aid is able to connect with nearly every modern electronic device for communication and entertainment, whether landline or cell phone, television, stereo system, computer or MP3 player.

“Pure Carat” is available in ten color variations: golden blond, beige, brown, dark blond, pearl white, silver, gray, granite, black and turquoise. Any of which can be exchanged for another by the hearing aid acoustician. Naturally, they are available right away.

The products mentioned here are not commercially available in all countries. Due to regulatory reasons the future availability in any country cannot be guaranteed. Further details are available from the local Siemens organizations.
