Nonlinear Device Noise Models:Thermodynamic Requirements

This paper proposes three tests to determine whether a given nonlinear device noise model is in agreement with accepted thermodynamic principles. These tests are applied to several models. One conclusion is that every Gaussian noise model for any nonlinear device predicts thermodynamically impossible circuit behavior: these models should be abandoned. But the nonlinear shot-noise model predicts thermodynamically acceptable behavior under a constraint derived here. Further, this constraint specifies the current noise amplitude at each operating point from knowledge of the device v - i curve alone. For the Gaussian and shot-noise models, this paper shows how the thermodynamic requirements can be reduced to concise mathematical tests involving no approximatio

Resumen tomado de la publicaci??n

Série tirée des essais de mise en commun de termes en vrac se référant aux acteurs, aux notions empruntées au social, au politique, à l'education, à la terminologie courante de la muséologie adaptée aux présupposés de la muséologie sociale

POPULATION = Terme générique pour désigner l’adhésion d’une population, ou d’un groupe significatif de citoyens d’un territoire d’appartenance, au projet de muséologie sociale. Celle-ci se mesure par le degré de participation, d’implication et de vision partagée, d’interaction au sein de la collectivité territoriale, son fief. PARTICIPANTS = Sont les acteurs actifs au sein de la population adhérante, partie prenante au projet de muséologie social. La participation se mesure selon le degré d’implication dans le projet et de compréhension de celui-ci (Intérêt, gestion partagée, militance, volonté de capacitation...) COOPÉRANT = Par solidarité, par engagement, il s’insère dans le système de l’action ccopérative, possédant ses règles propres, offrant sa contribution à l’unité de production conciliant la dimension sociale (de la muséologie), son idée au regroupement de personnes désireuses de contribuer à la production commune de biens de qualité au service de la population dont ils sont issus.

Strial capillary permeability following noise exposure in mice

A study of strial capillary permeability using fluorescent microspheres and immunohistochemistry in mice that do or do not exhibit a reduction in endocochlear potential following a single, intense noise exposure.

Development of curriculum in noise awareness

This paper presents a curriculum in noise awareness developed for use in the second and fourth grades, to teach children about the harmful effects of elevated noise levels.

Speech intelligibility in noise-induced hearing loss: effects of high-frequency compensation

This dissertation examines the frequency response that results in the maximum level of speech intelligibility for persons with noise-induced hearing loss.

Noise exposure in the operating room

This paper discusses a study done to determine noise levels in operating rooms

A comparison of physical measurements of pure-tones, third-octave bands of noise and third-octave bands of speech to subjective judgments of audibility threshold, MCL and UCL for three normally hearing listeners

This study investigates the relation between physical measurements of pure-tones, third-octave bands of noise and third-octave bands of speech and subjective judgments of auditory threshold, most-comfortable listening level (MCL) and uncomfortable-listening level (UCL) for three normally hearing listeners.

Noise levels and hearing conservation in a water treatment facility

This paper describes a study assessing the sound levels and noise exposures of a municipal water treatment plant to determine the level of employee noise exposure dosages and to make any necessary recommendations regarding reducing the risk of noise induced hearing loss in employees.

Role of alpha synuclein in noise induced hearing loss

The recent discovery of the contribution of alpha synuclein in the auditory system prompted further investigation of its functional role. Auditory brainstem response (ABR) and gap detection testing were completed on wild-type and transgenic M83 mice to assess the role of alpha synuclein in noise-induced hearing loss and central auditory function.

The effectiveness of noise cancellation headphones for hearing impaired listeners

This paper discusses the use of noise cancellation headphones for hearing aid users to reduce background noise in order to improve speech discrimination.

Bone-conducted tones masked by air-conducted noise

This paper presents a study designed to develop and evaluate a method for obtaining monaural thresholds for bone-conducted signals masked by air-conducted noises.

Noise exposure in the fire department

This paper discusses noise exposure to firefighters on the job and whether this contributes to noise induced hearing loss.
