A Robotics Institute team developed a framework that enables home robots to estimate noise levels in indoor environments by using only visual information — potentially leading to less-disruptive ...

An instrument for measuring the level of sound pressure in DECIBELs. Such measurements are called sound level readings. See: SOUND LEVEL. Sound level meters usually ...

Unwanted background sounds are sometimes called noise. When the sound level of this noise rises to higher levels, we refer to this as noise pollution. Sound levels are measured on a scale known as ...

FLIP's stability, 300-foot draft, and low acoustic noise levels made it uniquely suitable for a wide variety of research experiments. Hydrophones could be positioned at a variety of depths for ...
