This project is about the thought that urban noise is more needed than we may think. A lot of people can be really disturbed and upset about a noisy environment surrounding them. I want to show with this noise pod, a space where you can sit/lay while listening to everyday urban noise compositions, that noise can be really relaxing and enjoyable. Relaxation does not only come from the right choice of noise at the right time it also depends on the environment that you enjoy the soundscape in. This pod - a small capsule of space - is a place to sit by yourself, choose a noise composition and list

La pollution sonore est un problème majeur pour les résidents des zones urbaines. La directive Européenne 2002/49/CE impose aux états membres l’établissement de cartes de bruit. Ces dernières sont construites sur la base de l’indice énergétique Lden, également utilisé dans les relations dose-effet établies pour prédire la gêne. Toutefois, pour l’évaluation de la gêne due au bruit dans les zones urbaines, la pertinence de cet indice est souvent remise en question.

Noise of electronic devices can be measured by comparison using a noise source at input and an output noise meter. It is noise generator method. It can be used to easily obtaining equivalent input noise of semiconductor devices. But this method is usually recommended for higher frequencies, because measurement generator must give white noise. Besides this, we obtain only noise level at broad band.

There is an estimated 10 million Americans that suffer from permanent, irreversible hearing loss from their workplace. Many soldiers come back from battle with this damage, mainly from the high sound levels of their weapons that they are exposed to. The U.S. government spends over $250 million a year in compensation to those whose hearing has been damaged. There are current medicines that have proven to help eliminate or lessen the affects from certain types of noise induced hearing loss, specifically from prolonged expose.

Buildings located near airports may be subjected to significant noise levels due to aircraft flyovers. Aircraft noise is particularly annoying when compared to other traffic noises due to its intermittent nature. While noise control is typically performed at the source, sound insulation programs are in place to improve the acoustic performance of a residence affected by the flyovers. Noise Level Reduction (NLR) is a common metric used in the United States to determine whether a residence qualifies for such programs. Sound insulation programs are available to houses that have an indoor Day Nigh

Individual cells in a genetically identical population, exposed to the same environment, can show great variation in their protein expression levels. This is due to noise, which is inherent in many biological processes, due in part to the low molecule numbers and probabilistic interactions which lead to stochasticity. Much of the work in the field of noise and its propagation in gene expression networks, whether it is experimental, modelling or theoretical, has been conducted on networks/systems that occur within a single cell. However, cells do not exist solely in isolation and understanding

I tumori macroscopici e microscopici, dopo la loro prima fase di crescita, sono composti da un numero medio elevato di cellule. Così, in assenza di perturbazioni esterne, la loro crescita e i punti di equilibrio possono essere descritti da equazioni differenziali. Tuttavia, il tumore interagisce fortemente col macroambiente che lo circonda e di conseguenza una descrizione del tutto deterministica risulta a volte inappropriata. In questo caso si può considerare l'interazione con fluttuazioni statistiche, causate da disturbi esterni, utilizzando le equazioni differenziali stocastiche (SDE). Qu

This thesis examines signal modeling techniques and their application to ambient ocean noise for purposes of noise removal and for generating realistic synthetic noise to add to synthetically generated transient signals. Higher order statistics of the noise are examined to test for Gaussianity. Stochastic approaches to AR, MA, and ARMA modeling are compared to see which technique yields the "best" synthetic noise. Results from the modeling process are used to develop a short-time Wiener filter which can be used to condition a real signal for further processing through effective noi

Oscillator phase noise is an important factor in designing radio frequency (RF) communications hardware. Phase noise directly contributes to adjacent-channel interference and an increase in bit error rate (BER). <p> Understanding the operation of an oscillator can help with the oscillator design process. Also, the understanding of the noise processes within an oscillator can add insight to the design process, allowing an intelligent low-noise design. It will be shown that although simulation software can be helpful, the understanding of the oscillator operation is a valuable tool in the desi

Tire-pavement interaction noise is one of the dominant sources of vehicle noise, and one of the most significant sources of urban noise pollution. One critical generation mechanism of tire-pavement interaction noise is tire tread excitation. The tire tread contributes to the tire-pavement interaction noise mainly through two mechanisms: (1) tread block impact, and (2) the compression and expansion of the air in the tread groove at the contact patch. The tread pattern is the critical part of the tire design since it can be easily modified. Hence, the main focus of this study is to quantify the

Noise or interference is often assumed to be a random process. Conventional linear filtering, control or prediction techniques are used to cancel or reduce the noise. However, some noise processes have been shown to be nonlinear and deterministic. These nonlinear deterministic noise processes appear to be random when analysed with second order statistics. As nonlinear processes are widespread in nature it may be beneficial to exploit the coherence of the nonlinear deterministic noise with nonlinear filtering techniques. The nonlinear deterministic noise processes used in this thesis are genera

This thesis studies the prediction and reduction of installed jet noise, combining both analytical and experimental techniques. In the prediction part, it starts with formulating a low-order but robust isolated jet noise prediction model, based on which a remarkably fast code with pre-informed data is developed. A semi-empirical low-order model is then developed to predict installed jet noise. The model consists of two parts, the first of which is based on the Lighthill's acoustic analogy theory. The second part embraces Amiet's approach to model the sound due to the scattering of jet instabil

碩士<br>國立臺灣大學<br>電機工程學研究所<br>89<br>Magnetic Resonance Imaging (MRI) is one of the fast growing technology in medical imaging. With its non-radioactive, and non- invasive properties, MRI has contributed to a tremendous advance in medical diagnosis technology. However, it still has some limitations and problems. The loud acoustic noise generated by gradient switching is annoying patients. According to researches, noise generating by clinical MRI would up to 100dB. When using the rapid imaging method- echo-planar imaging (EPI), it will have more serious acoustic problems, because of higher slew ra

Abstract The paintings in White Noise are a response to temporal lighting conditions that occur at night. A discussion of sensory affect demonstrates how perception is inextricably connected to the body’s sensory capabilities such as sound and touch. By examining Maurice Merleau-Ponty’s theory of phenomenology and looking at Gestalt Psychology based experiments it is made clear that seeing whole and complete forms in the world is a product of embodied perceptual experience. I recall early experiences of being affected by light describing the optical illusion of the afterimage and then move i

The image of our metropolis is the product of our economy. Commercial vernacular architecture in the United States since 1950 has become increasingly generic and anonymous. This is the direct result of a shift in proprietorship from individual to joint ventures in ownership of built form. Joint ventures in ownership, in turn, allow for an increase in the scale of built form, or 'bigness,' which dislodges or shifts the fundamental architectural volume or unit. This new unit appears on frontage roads across the nation, and Houston's own 'feeder' roads are a prime example of this changing space o
