murmur
Low, continuous sound
Murmur is a soft, indistinct sound—voices too low to make out clearly, or continuous background noise like wind or water: a murmur of conversation from the next room.
To murmur is to speak quietly, often intimately or complainingly.
A heart murmur is an abnormal sound detected through a stethoscope, indicating turbulent blood flow.
