SOUND INSULATION
1. WHAT IS SOUND INSULATION?
We live in housing, school, workplace and so on. to prevent the harmful effects of noise by isolating buildings and the environment from unwanted noises; Recording studios, cinema, concert hall etc. to create the necessary usage conditions by isolating the spaces from unwanted sounds; generator, booster, heater etc. yapılan Sound insulation ara is the applications made with the aim of isolating noisy spaces and reducing the noise they emit to the environment.
Sound insulation basically covers the measures to be taken to minimize the harmful effects of noise on human beings. Noise is an undesirable set of undesirable sound that has different frequency components and is often variable over time.
Especially in areas where urbanization is unplanned, noise is one of the factors damaging human health and comfort. Disturbing noises from a surrounding factory, severe noise in the residential area around the airport, vendor voices, traffic noises, conversations from the neighbor can be disturbing by people perceiving it as different doses of noise.
In some areas, low volume is one of the most important requirements of the job. The sound level in radio broadcasting and music studios should be low, create a quiet and peaceful environment for patients in a hospital, cut out the noise coming from outside the school, building are the problems to be solved during the construction phase. In order to provide a peaceful environment in buildings, it is necessary to struggle with noise.
Two methods are mainly used to combat noise. Acoustic regulation and sound insulation. Acoustic regulation is the regulation of the reflection time in the indoor environment. Sound insulation, on the other hand, is the amount of sound transmitted by building elements.
to reduce the process.
2. ADVANTAGES OF SOUND INSULATION
2.1. Sound Insulation Provides Healthy and Comfortable Environments
Noise is undesirable and uncomfortable for our comfort. In addition to this disorder, it has negative effects on individuals in terms of psychological, physiological and performance. Noise, behavior disorders, decrease in working efficiency, hearing loss, tinnitus and some psychological diseases may be the cause.

2.2.Sound Insulation Makes People Efficient
Noise as a result of the factory and so on. the productivity of workers in industrial plants is reduced, their attention is distracted and as a result occupational accidents occur. Decreasing work efficiency due to noise can also harm institutions economically. A similar effect is seen on students studying. Students who are exposed to noise cannot understand the information efficiently because their concentration is distorted by distracting them. Research on the inhabitants of Munich Airport concluded that aircraft noise reduced children's long-term recall and comprehension skills. People need to be purified from noise by sound insulation in order to continue their activities efficiently.
