INTELLISONIC
The intelligibility and use of mobile communications
are often impeded by the impact of noise from the
immediate environment. IntelliSonic is a software-based
speech enhancement technology that when coupled
with Knowles’ microphones, reduces the effects of
reverberation, directionally interfering speech,
background noise and annoying acoustic echo.
COMPLETE SOLUTION
When you consider the interdependency of microphone design, acoustic porting, and sound signal conditioning, it's easy to see why Knowles
Acoustics has taken an integrated approach to your acoustic system needs.
