The Danavox Danalogic is a digital hearing instrument that is widely credited around the world. Danalogic has over twice the processing power of other instruments in its category, and uses PC-like, software-based digital technology. Thus Danalogic is able to improve upon the sound quality and sound processing capabilities of other instruments, while adding "smart" capabilities of its own. These include a continually active ("search and destroy") feedback suppression system, which detects feedback before it becomes audible and crushes it with no loss in instrument performance. Danalogic is also available with digital noise reduction, and two-microphone directional amplification, to improve speech understanding in noise. With a soft warning tone, it even informs users of impending battery failure.
