- Industrial Noise Control and Acoustics
Acoustics is a branch of physics that deals with the study of mechanical waves in gases, liquids, and solids including topics such as vibration , sound , ultrasound and infrasound. A scientist who works in the field of acoustics is an acoustician while someone working in the field of acoustics technology may be called an acoustical engineer. The application of acoustics is present in almost all aspects of modern society with the most obvious being the audio and noise control industries. Hearing is one of the most crucial means of survival in the animal world and speech is one of the most distinctive characteristics of human development and culture. Accordingly, the science of acoustics spreads across many facets of human society—music, medicine, architecture, industrial production, warfare and more.
Industrial Noise Control and Acoustics by Randall F Barron
Research has shown that exposure to high levels of noise can result in physical complications such as debilitating heart attacks, stroke 2 , and diabetes 3. At the same time, noise pollution also puts a strain on our mental state, which can lead to headaches, depression 4 , and accidents from weariness 5. And yet, this invisible threat shows no signs of slowing down. Noise from urbanisation and population are growing. New vehicles are coming up with louder and louder horns.
Meanwhile, research has shown that both people and birds are louder when they live in the city, as compared to their country counterparts, in order to stand out from the din of urban life 6. This will help us implement more effective sound control solutions and avoid the harmful effects of noise. Strategies to reduce noise pollution One of the key strategies to reducing the adverse effects of noise pollution is to plan and design buildings around the objective of effective noise control.
This is because high-density stone wool has proven acoustic capabilities that allow it to isolate and control vibrations, thus efficiently absorbing sound and reducing noise. Such insulation can provide invaluable solutions at transport sites and entertainment venues, both of which are significant sources of noise. Common noise barriers come in the form of weather stripping which stone wool can be used for and double-paned windows, especially if you live in a noisy city or near an airport.
As an added bonus, applying these changes to a building can also reduce heating and cooling bills, and help protect the environment from harmful carbon emissions.
For example, the Transport Strategy published in notes that a fifth of Londoners are annoyed or disturbed by noise in their homes and that the most disturbing noise is created by buses and lorries. The Transport Strategy suggests that putting noise barriers in place in some areas, along with reviewing sound insulation regulations, may be a solution.
If you are unable to eliminate unpleasant noise from your surroundings, you can actually create a healthier environment by replacing stress-inducing environmental sounds with more pleasing ones. These sounds can help to drown out jarring environmental noises that can distract you or disturb your sleep, in turn achieving a soothing effect. Playing music that you enjoy can also accomplish a similar result, while improving your mood. Doing this may feel like you are simply trading in some sounds for others, but the sounds of nature and music can feel more relaxing, and therefore better for your health.
After all, sounds become noise depending on what you actually want to hear. Environmental noise control There are also other strategies in place to deal with noise. Noise maps are created every five years and to align action plans with the Environmental Noise Directive Simultaneously, good environmental noise quality is preserved by identifying Quiet Areas, while the public is educated on environmental noise and its effects in order to promote more considerate behaviour in relation to noise Hence, another way of reducing the impact of noise if you are unable to eliminate it, is to create distance between yourself and the source of the noise.
At the same time, if you are the source of the noise, it is common courtesy to avoid doing it close to other people. For example, you can step outside to take a phone call during work, instead of broadcasting it to the entire office. This provides better assistance for people who are struggling to find a tranquil place to spend their time.
Ultimately, we need to continue discovering and implementing new and innovative ways to limit the negative impact of noise pollution, so that we can raise our efforts in the war on noise and safeguard our health and happiness.

Active noise control: a marriage of acoustics and control Abstract: In a response to a growing demand for environments of 70 dB or less noise levels, many industrial sectors have focused their attention on the development of quality products with some form of noise control cancellation system. Automotive manufacturers, aircraft designers; engine manufacturers; appliance industries; producers of heating, ventilating, and air conditioning systems, etc. Active noise control ANC has proven to be the most effective technology, especially for low frequency excitations that the human is more sensitive to.

Courses in acoustics and acoustical engineering were taught there in the s and s, and a series of summer courses were offered. Purdue University and others began to offer undergraduate courses in noise control in the s, soon after enactment of the Noise Control Act of Most existing noise control and acoustics courses are taught either at the graduate level or are noncredit short courses.
Urban and industrial noise pollution is present in virtually every country in the world. Noise pollution studies are therefore needed to find solutions to improve the quality of life in cities. This book contains eighteen chapters that address the problem of noise in urban and industrial environments. One of the chapters evaluates how noise is perceived by the residents of three cities with different population densities, and a methodology is presented for the assessment of road traffic noise in one of these cities, using noise maps. Noise pollution is also evaluated on a university campus and at leisure locations such as public parks.

Дальше бежать было некуда. Как трасса, на продолжение которой не хватило денег, улочка вдруг оборвалась. Перед ним была высокая стена, деревянная скамья и больше. Он посмотрел вверх, на крышу трехэтажного дома, развернулся и бросился назад, но почти тут же остановился. В некотором отдалении от него возникла фигура человека, приближавшегося медленно и неотвратимо.
У немца. Его взял немец. Дэвид почувствовал, как пол уходит у него из-под ног. - Немец. Какой немец.

Нет! - Он схватился за голову. - Нет. Шестиэтажная ракета содрогалась.
