Natural sound technology
Hear better with natural sound technology
Your world is full of amazing sounds. Hushed. Sudden. Beautiful. Magical. Siemens hearing instruments are equipped with an intuitive two-component amplification system that enables you to hear sounds exactly the way they should be heard. By automatically reducing the amplification for loud sounds while increasing it for soft sounds, the hearing instrument simulates all levels of normal hearing. After all, not all sounds are created equal.
Some hearing instrument wearers may be bothered by sounds that are uncomfortably loud. But the AGC-I and the new multichannel AGC-O systems (AGC = Automatic Gain Control) work together to help balance wearers’ perceptions of soft, average, and loud sounds, and ensure that sounds are audible and recognizable without being too loud. For optimal flexibility, these characteristics are fully adjustable in up to 16 channels.
Know where the sound comes from
Front. Back. Left. Right. The ability to accurately locate the source of sounds is key to hearing more naturally.
Localization of sounds can be a big challenge, especially with traditional BTE instruments, which reduce directionality at frequencies above 1.5 kHz compared to the unaided ear. Our breakthrough TruEar™ technology and e2e wireless™ 2.0* set a new standard for improving sound localization. TruEar simulates the acoustics to restore the natural directivity of the human outer ear, thereby improving front-back localization. It helps you distinguish sounds in front of you from those behind you. Meanwhile, our e2e wireless 2.0 technology wirelessly synchronizes the instruments’ settings for better localization in every direction. Studies have shown that this technology can improve the left-right localization
of sounds by up to 40%1.
*e2e wireless 2.0 utilizes a transmission frequency of 3.28 MHz, selected in accordance with the International Telecommunication Union (ITU) recommended frequency band 3.155 MHz to 3.400 MHz for wireless hearing instruments.

Life sounds richer, fuller, and more natural than ever
SoundBrilliance™ is the remarkable new technology that enhances the perception of higher pitched sounds. SoundBrilliance adds richness and fullness to the hearing instrument’s sound by providing the perception of acoustic stimulation of up to 12 kHz. It analyzes the hearing instrument’s input signals and adds high frequencies whenever appropriate in order to provide a full sound quality. This feature is particularly useful where sound signals are wirelessly transmitted. Bluetooth® transmission, for example, is bandlimited to 7.5 kHz, but SoundBrilliance adds high frequencies to the original signals. This enables a much fuller sound, especially when listen to music.
