dynamic noise suppressor dynamic noise suppressor[dī¦nam·ik ′nȯiz sə‚pres·ər] (engineering acoustics) An audio-frequency filter circuit that automatically adjusts its band-pass limits according to signal level, generally by means of reactance tubes; at low signal levels, when noise becomes more noticeable, the circuit reduces the low-frequency response and sometimes also reduces the high-frequency response. |
