Siemens Hearing Instruments are designed with an advanced level of technology. The long list of innovative features grows even longer for premium segment hearing instruments. In the past, "volume controls" were always needed to control the instrument. Today, CENTRA's learning controls handle volume control, automatically. More advanced instruments have directional microphones that focus microphones in noisy environments like at a restaurant or a party. Newer hearing instrument-families offer a "remote control" to provide bi-directional remote control to volume, program and battery status.

Like everything else in the world, digital technology is revolutionizing hearing instruments. It used to be that non-digital, analogue instruments needed manual volume controls and firm program settings. Today, even though manual controls are still an option, digital instruments can collect and save information about different hearing situations making it possible to automatically adjust to these different hearing situations. This is truly amazing!
