NOISE CONTROL IN BUILDINGS

Nowadays due to increased urbanization and industrialization, there is a tremendous increase in noise pollution. Noise is an unwanted sound. It creates a huge discomfort to the occupants in the building. There are many structures like schools, corporate offices, and residential buildings that are constructed nearby highways faces a huge problem of noise pollution due to heavy traffic.

So it is necessary that structures should be constructed in such a way that they should resist noise and keep the internal environment soundproof. It is today’s need that we should design and planned structures for better Acoustic control.


Acoustic of Buildings

Acoustic control of Buildings is the science of controlling the unwanted noise in the living environment. It is a minimization of sound transmission from one place to another place and the control of the characteristics of sound. It is an implementation of techniques for making structure soundproof structures. This is an economical method that saves the cost of installation of acoustic Windows and glass.


Construction Techniques for Noise Control in Buildings

1. Construction of walls

Walls are the important structural components of the Buildings which protect the internal environment from the external noise.

2. Use of Cavity walls in the partition

The use of cavity walls in partition proves to be very efficient for sound resistance in the Buildings.

3. By increasing thickness and mass of the wall

The noise resistance of the material depends upon the mass of that material. The more the mass of material more will be noise resistance. The concrete walls provide more sound insulation as compared to wooden walls because of its higher mass.

4. Use of Acoustic blankets in airspace

This is also known as isolation blankets which can increase sound attenuation when placed in the airspace.

They can attenuate noise up to 10 dB

5. Use of different panels

The panels used should be of different materials and thicknesses. This will improve the sound insulation property of the walls.

6. Construction of windows

Windows are one of the major sources from where the sound enters into the structures. So that is necessary to take into consideration while acoustic planning of the structures.

7. Reduction in size of windows

It is a very useful method to resist the sound enters into the structures. This is an economical method that saves the cost of installation of acoustic Windows and glass.

8. Increasing thickness of the glass

The noise can be resisted by increasing the thickness of the glass. It is also necessary that proper sealing should be done in order to increase the effectiveness of soundproofing.

9. Installation of double glazed 

It is an effective method that increases airspace width, glass thickness which helps in noise resistance.

Traffic Engineering Design Process

Pre-Design Considerations Site Analysis Before creating a design, traffic engineers need to conduct a site analysis to determine what needs the site may have for the area’s traffic. They will need to take note of the surrounding area – businesses, schools, railways, protected lands, etc. – and investigate any local policies that might affect their work.  Traffic Surveys A traffic survey is a survey conducted by traffic engineers to determine how traffic moves through a particular area. These usually take 2-4 days per intersection to complete and need to occur throughout the day to ensure both peak and non-peak hours are factored in. One of the most popular ways a traffic survey is conducted is with the use of rubber hoses. These hoses run across the road and connect to a meter that counts each vehicle that passes while also determining what type of vehicle it is. These hoses also collect data on what speed the vehicle is going when it passes over the hose.  Traffic engineers will als

  9 Elements for Designing Your Ideal Bathroom: A Practical Guide for Function and Style Designing a Functional Bathroom When it comes to your home, few spaces are as personal as the bathroom. It’s not just a functional necessity; it’s a sanctuary where you start and end your day. Creating a bathroom that seamlessly blends function with style is key to turning it into your ideal oasis. Let’s explore the essential elements that make up a well-designed and practical bathroom. 1. Storage Solutions: Declutter and Delight No one likes a cluttered bathroom. Invest in built-in cabinets, shelves, and storage niches to keep your essentials organized and within reach. Vertical storage is your secret weapon, especially in smaller spaces. A tidy bathroom is a peaceful one. 2. Layout Matters: The Bathroom Work Triangle Ever heard of the bathroom work triangle? It’s all about optimizing the layout for easy movement. Position the sink, toilet, and shower or bathtub strategically to crea
