Can quantifying the relative intensity of a person’s free-living physical activity predict how they respond to a physical activity intervention? Findings from the PACES RCT

Objectives To determine whether quantifying both the absolute and relative intensity of accelerometer-assessed physical activity (PA) can inform PA interventions. We hypothesised that individuals ...

The Sound Intensity

Sound intensity is referred as the sound power per unit area. It illustrates the flow of acoustic energy produced by a sound source. Not like simple microphones and sound level meters, sound intensity ...

Loudness constancy with varying sound source distance

In the natural world, many situations exist in which a percept remains constant in the presence of profound changes in the physical stimulus affecting the sensory receptors. Some of the most ...
