发明名称 Telephone sound pollution sound reduction system having hollow tube applied telephone with sound detector and sounds analyzed/transformed transmitting active/passive counteracting sound.
摘要 The sound reduction mechanism has a hollow tube applied to a telephone with a sound detector. Sounds are analyzed and transformed transmitting active and passive sounds. Sounds produced during telephone calls are analyzed for background noise and counteracting sounds produced. The sound reduction mechanism has a hollow tube with a sound detector, which is applied to the telephone. Passive and active sounds are trapped within the mechanical construction.
