It contains an equalizer to reduce frequency distortion
, and supports online video streaming.
By estimating the channel characteristics, this block equalizes the frequency distortion
due to the multipath4 delay spread.
In specialty applications, where sound attenuation with minimal change in frequency distortion
is necessary, custom molded earplugs may be required.
Noise and frequency distortion
can seriously undercut the intelligibility of human speech even though its audibility is good.
The rolloff in high frequency distortion
of both devices is due to their inherent high frequency rolloff.
The low frequency distortion
is constant, with improvement in distortion intercept point at the higher frequencies.
