Impulsive noise: A brief review
Short duration impulsive noise is typically generated by a release of pressure (impulse) or a collision of solid objects (impact). In animal models these noises have been shown to be more damaging to the ear than continuous noise of equal energy (Hamernik and Henderson, 1974; Dunn et al., 1991; Hamernik et al., 1994). Impulsive noises are common in manufacturing, construction, public safety and...
متن کاملLong-term noise exposures: A brief review
Occupational regulations are developed to conserve the hearing of a worker noise-exposed for 8 h per day. Workers often work longer shifts. In order to account for longer exposures, regulators have adopted variations of the equal energy hypothesis in which the ear is modeled as an integrator of acoustic energy over time. Thus time and energy can be traded to produce equal hearing loss. This res...
متن کاملReview of active noise control algorithms for impulsive noise control
Active noise control is gaining popularity in recent years. Especially, active control of impulsive noise is of great interest. Due to specific nature of such noise, standard approach to active control is not satisfying. This paper reviews existing algorithms specifically developed for impulsive noise control. Performance of the algorithms is verified using computer simulations and several nois...
متن کامل12 Impulsive Noise
mpulsive noise consists of relatively short duration " on/off " noise pulses, caused by a variety of sources, such as switching noise, adverse channel environments in a communication system, dropouts or surface degradation of audio recordings, clicks from computer keyboards, etc. An impulsive noise filter can be used for enhancing the quality and intelligibility of noisy signals, and for achiev...
متن کاملP158: Epilepsy and Anxiety: A Brief Review
Epilepsy is a brain disorder that causes people to have recurring seizures. The seizures happen when clusters of nerve cells, or neurons, in the brain send out the wrong signals. Up to 50 or 60% of patients with chronic epilepsy have various mood disorders including depression and anxiety. Although the affective and cognitive effects of epilepsy have long received attention, the anxiety spectru...
