Noise-enhanced hearing sensitivity

Contrary to our intuition, we demonstrate that noise can be a benefit factor that enhances our hearing sensitivity. We measured subjects' abilities to detect near threshold pure tone in different noise levels. The results show that by adding noise of certain level, the subjects can detect near...

Summary:Contrary to our intuition, we demonstrate that noise can be a benefit factor that enhances our hearing sensitivity. We measured subjects' abilities to detect near threshold pure tone in different noise levels. The results show that by adding noise of certain level, the subjects can detect near threshold pure tone better than without noise.
