Definition
"Background noise" refers to the constant, low-level sounds or vibrations present in an environment. Think of it as the Earth's hum or murmur. π It can include things like traffic, wind, or even faint seismic activity. In seismology, background noise can sometimes interfere with the detection of smaller earthquakes. It's the constant chatter that seismologists have to filter out. π While it's often unwanted, it can also provide valuable information about the environment. βΉοΈ
