What is sound insulation? : What is sound insulation and how is it done? Unwanted noise and noises negatively affect our life comfort as well as our life health. Especially the common neighbor wall, sidewalls, and ceiling sounds coming from above, foot heel vibration and impact to insulate the sounds moving from the floor and the products and the application should be correct and effective in order not to disturb you. This article is a technical information article that is prepared based on technical data and intended to use the correct product. Sound insulation, which aims to minimize echo problems such as residences, workplaces, factories, offices and stores, cafes, and restaurants, where human voices are mixed with each other, offers a quality life for you. The main rule in sound insulation is to reduce the sound to the point where it is produced, as it moves radially with air particles and the objects it touches. For this, acoustic sponges and sound insulation mattresses will be the solution to your problems. At the same time, click on how many DB (decibels) insulation comfort you need for the ceiling, wall, and the floor below You can choose the materials you need.
What is Sound Insulation?: Sound insulation means isolating the sound in the environment with sound insulation materials. It is the best and the most efficient solution to protect ourselves from the unwanted sounds and noises in our daily life. With sound insulation, it is possible to prevent the sound waves from passing from one place to another and to reduce the noise at its point of source. Sound insulation problems usually occur in places such as houses, meeting rooms, generator rooms, machine rooms, schools, libraries, and call centers.
1. Sound Insulation
The system intended for sound insulation includes the measurements to minimize the damage caused by the noise on the human. Any sound, that is incompatible, irregular, and disturbing is called noise.
1.1 Preventing the Damages of the Sound: Noise pollution is one of the problems that are harmful to human health and life comfort in cities that have unplanned urbanization. Sounds and noises coming from factories, airports, traffic, and our neighbors are disturbing and harmful to our health.
1.2 Sound: Beams that move through air particles are matters. Two different methods are used for preventing unwanted sound waves and noise. Acoustic regulations and sound insulation. Acoustic regulations are applied to regulate the reverberation time indoors, that is to say, to decrease the intensity of sound by absorbing the sound waves at their source. Sound insulation is applied for providing the transient loss of the sound from one place to another with sound isolation products.
2. Advantages of Sound Insulation
2.1. Sound Insulation Provides Healthy and Comfortable Environments: Noise is an unwanted and disturbing factor for our comfort and, living in an environment without noise pollution is not a luxury but a requirement. This factor causes psychological and physiological disturbances as well as negative issues in terms of performance.
30-65 dBA I. 1st Grade Noises
Loss of Concentration
65-90 dBA II. 2nd Grade Noises
Changes in Heartbeat
Decreased Pressure in the Brain
90-120 dBA III. 3rd Grade Noises
120-140 dBA IV. 4th Grade Noises
140 dBA V. 5th Grade Noises
2.2. Sound Insulation Makes People Efficient
Because of the disturbance caused by the noise, the performance of the workers who work in industrial places like factories decreases, and as a result of that, distractibility and occupational accidents happen. The decrease in performance affects the establishments economically. A similar effect can also be seen with students. Students exposed to noise are distracted, and their concentration is disturbed, so they move away from the lesson and cannot perceive the given information healthily and efficiently. It has been proven by research that aircraft noise reduces long-term remembering and perception skills. To set an example as a result of the researches which has been carried out on inhabitants who live around Munich Airport, it has been proven that the noise is harmful to human health. Humans must be isolated from noise with sound insulation to continue their life efficiently.
3. SOUND INSULATION MATERIALS
I. Building Insulation
Wall, Floor, Roof Applications: Acoustic sponges, rubber barriers, soft polyurethane based sponges, melamine sponge, felt, perforated metals, perforated woods, perforated gypsum panels, cork. Flooring Applications (to prevent only the impact sound): Polyethylene, rubber foam, merchandise materials made of textile waste.
II. Insulating Glass Units Acoustic Laminated Glass Solutions
III. Technical (Industrial) Insulation Acoustic sponge, acoustic products, acoustic mattresses, polyethylene, polyurethane, rubber foam, suspension equipment, hangers, sound absorbers, etc.
