Echo suppression and echo cancellation are methods used in telephony to improve voice quality by preventing echo from being created or removing it after it is already present. In addition to improving subjective audio quality, echo suppression increases the capacity achieved through silence suppression by preventing echo from traveling across a ...
Some incorporate acoustic echo cancellation to allow setups with acoustic paths between loudspeakers carrying phone audio and microphones feeding the phone lines. In studio applications, a hybrid needs particularly good send-to-receive isolation. When too much of the host audio appears at the hybrid's output, there will be a number of defects.
Acoustic echo cancellation (AEC) is a processing algorithm that uses the knowledge of audio output to monitor audio input and filter from it noises that echo back after some time delay. If unattended, these echoes can be re-amplified several times, leading to problems including:

Adaptive feedback cancellation originated during the evolution of the hearing aid. The hearing aid became digital, and as such feedback cancellation was needed. In 1980 a directional microphone was introduced in the digital hearing aid, and adaptive feedback cancellation was created to block external noise that the microphone picked up. Today ...
Acoustic signal processing is the electronic manipulation of acoustic signals. Applications include: active noise control; design for hearing aids or cochlear implants; echo cancellation; music information retrieval, and perceptual coding (e.g. MP3 or Opus). [21]
Social Security is the U.S. government's biggest program; as of June 30, 2024, about 67.9 million people, or one in five Americans, collected Social Security benefits. This year, we're seeing a...
G.165 is an ITU-T standard for echo cancellers. It is primarily used in telephony. Echo can occur on telephone lines when a user's voice is reflected back to them from further down the line. This can be distracting for the user and even make conversation unintelligible. Echo can also interfere with data transmission.
