Tinnitus - Tinnitus A police officer fires his handgun while target practicing. He forgot to put on his ear muffs and suddenly after the shot, he hears a faint buzzing sound. In this example, over time, the ringing will probably fade for the officer. Almost everyone will experience tinnitus in their lifetime. After all, loud noises are impossible to avoid completely. There is only a problem when the sound from the tinnitus does not stop, or it continues to get louder with time. For many people around the world, the ringing, buzzing, hissing or chirping sounds that make up tinnitus (tin-Night-us; Tin-nit-us) or acoustic trauma never go away (Alliance)....   [tags: Health Hearing Loss Noise Loud Essays]

Activation of Protein Kinases by Means of Stochastic Resonance - ... It often occurs in bi-stable systems or in systems with a sensory threshold and when the input signal to the system is "sub-threshold". As pointed out for lower noise intensities, the signal does not cause the device to cross threshold, so little signal is passed through it. For large noise intensities, the output is dominated by the noise, also leading to a low signal-to-noise ratio. For moderate intensities, the noise allows the signal to reach threshold, but the noise intensity is not so large as to swamp it....   [tags: cellular function]

Analog and Digital Signalling - Part 1: General Review of Signalling a.) Explain the fundamental differences of analog and digital signalling. Baher (2001, p. 2) states that the natural world we live in, as well as most artificial sources, produce signals which we have grown accustomed to consider mainly of the analog type. This means that the signal f (t) is defined, somehow, for all values of the continuous variable t, and its amplitude can assume any value of a continuous range. Such a signal is referred to as an analog signal....   [tags: Signalling, electronics,] 1245 words

Experiments have revealed that, with temperature, acoustic signals present a decrease of energy under the form of amplitude and frequency decay. An exponential frequency drift with temperature was observed and empirically evaluated into a frequency-temperature function. This frequency-temperature analytic function was used to compensate for the “stretch” of the time traces, effect directly connected with the temperature influence. The compensation strategy proposed improved by -14 dB the residual resulting from subtraction of two sets of data registered on undamaged plate, but at different temperatures, Figure 2....   [tags: Temperature, Structures]

While hearing aids amplify acoustic sounds so they may be detected and understood by damaged ears, a cochlear implant bypasses those damaged portions of the ear and sends direct stimulation to the auditory nerve using electrodes arrayed on the scala tympani (NIDCD,2013). While many recipients of this innovative device report various levels of success, there remain to be common reports of difficulty with speech processing, especially in the presence of noise....   [tags: Hearing Study]
