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]
Noise-induced hearing loss is a permanent shift in pure-tone thresholds, resulting in sensorineural hearing loss. The severity of a threshold shift is dependent on duration and severity of noise exposure. Noise-induced threshold shifts are seen as a notch on an audiogram from 3000 to 6000 Hz, but most often at 4000 Hz. [16]
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]
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.
The horizontal axis shows frequency in Hertz. In acoustics, loudness is the subjective perception of sound pressure.More formally, it is defined as the "attribute of auditory sensation in terms of which sounds can be ordered on a scale extending from quiet to loud". [1]
Psychoacoustic tuning curves can be measured using the notched-noise method. This form of measurement can take a considerable amount of time and can take around 30 minutes to find each masked threshold. [10] In the notched-noise method the subject is presented with a notched noise as the masker and a sinusoid (pure tone) as the signal.
Physiological response. stressor (noise, heat shock or stress) conditioning activates hormonal glands: the HPA axis. Note that the HPA axis is associated to the immune system [122] this HPA axis activation results in the up regulation of glucocorticoid receptors (GR) in the cochlea and the paraventricular nucleus (PVN) of the hypothalamus.
Listener fatigue (also known as listening fatigue or ear fatigue) is a phenomenon that occurs after prolonged exposure to an auditory stimulus.Symptoms include tiredness, discomfort, pain, and loss of sensitivity.
