What is the place theory of pitch detection?
the number of hair cells that are stimulated
Signal detection theory applies when signal detection is more important than signal fidelity. Safety is an example of an imperative that will influence whether a sensory threshold is low or high. The penalty of a missed detection vs a false detection. Radar is designed with this in mind. Safety is not the main imperative in all biological systems, where fidelity is more important. C=capacity of channel R=information to be transmitted E=errors When R>C the problem…
Signal detection theory, is a means to quantify the ability to discern between signal and noise. There are a number of determiners of how a detecting system will detect a signal, and where its threshold levels will be. When the detecting system is a human being, experience, expectations, physiological state (e.g. fatigue) and other factors can affect the threshold applied
Yes, there most certanly is. They seem a bit expansive, but gas leaks can be too. I will place a link or two in the comments that you can look at if you want. I can't put them here. There are a number of detection methods which can be used to detect gas leaks. These include Infrared Point, Infrared Imaging, Ultrasonic, Holographic, Semiconductor, and Electrochemical detection.
