Physiological noise is any physical attribute that affects the way you communicate a message. [6] When you experience physiological noise your body is causing your mind to lose focus on the message you're trying to receive. This results in a miscommunication of the message and in some cases a loss of the message completely. [7]
Noise is a term often used to refer to an unwanted sound. In science and engineering, noise is an undesirable component that obscures a wanted signal. However, in sound perception it can often be used to identify the source of a sound and is an important component of timbre perception (see below).
Connectivity noise: Noise that arises from the number of connections and non-uniformity that a neuron has with other neurons within a neuronal network. There is a stronger presence of sub-threshold noise when the interconnectivity is strengthened, or the number of connection to other neurons is increased. [10] The opposite remains true, too.
It is the branch of science studying the psychological responses associated with sound including noise, speech, and music. Psychoacoustics is an interdisciplinary field including psychology, acoustics , electronic engineering, physics, biology, physiology, and computer science.
Sound annoyance is a subjective matter and cannot be covered by law. In the Netherlands the government set up laws to protect households and other noise-sensitive buildings like hospitals and schools from noise pollution. There are different laws for different sound sources; airplanes, traffic, industry and neighbours. [13]
This noise may range from ailments and illness, all the way to emotions like arousal. Both sides of the spectrum can affect the audience's attention, for example, a speaker giving a speech while under the illness of a cold will have a stuffy nose or a recurring cough, which can take the audience's focus from the speaker to his cold.
When sensorineural hearing loss (damage to the cochlea or in the brain) is present, the perception of loudness is altered. Sounds at low levels (often perceived by those without hearing loss as relatively quiet) are no longer audible to the hearing impaired, but sounds at high levels often are perceived as having the same loudness as they would for an unimpaired listener.
Physiology (/ ˌ f ɪ z i ˈ ɒ l ə dʒ i /; from Ancient Greek φύσις (phúsis) 'nature, origin' and -λογία () 'study of') [1] is the scientific study of functions and mechanisms in a living system.
