Noise Mapping

 

Noise Mapping

A noise mapping study is a detailed analysis of the noise levels in a specific area. It involves the use of sound sensors, computer modeling or software, and data analysis to create a detailed illustration of noise levels in the area of study.

Noise contour mapping is simply a colored map to indicate the intensity of noise on the map of the place of study conducted. It is very helpful to identify the area where noise levels exceed the recommended threshold.

Noise Mapping

 

What is meant by Noise Mapping?

 Noise mapping is a method of collecting noise level data using noise monitoring sensors, data modeling, and visualizing in a graphical manner. The purpose of this process is to get a detailed map of noise levels that can highlight areas where noise levels are exceeded so that measures can be taken to reduce noise.

 

Types of Noise Mapping

There are many types of Noise Mapping but the most popular types are

  • Strategic Noise Mapping: This type is used by government agencies and large corporates to measure noise reduction measures they have taken for big projects
  • Environmental Noise Mapping: Environmental noise mapping is done by environmental Protection agencies to measure the impact of noise on the environment and wildlife.
  • Community Noise mapping: In this type, local communities are taken into consideration where noise pollution is very high and to develop strategies to reduce noise levels.

Noise Mapping Procedure

Noise Mapping Procedures can be divided into three types based on the tools used i.e., Sound Sensors, Computer Simulation, and Data Analysis.

In the Noise mapping procedure, Sound Sensors play a very important role. Noise level monitoring Sensors are placed in strategic locations in the study area. Data is collected periodically from noise sensors and it is used to create a detailed noise map that shows the distribution of noise levels in the study area.

Computer Modelling or Noise mapping software is another tool used in Noise Mapping procedures. In this method map is fed to the software and based on conditions it can generate and simulate noise patterns based on conditions. For e.g., if we create a road or construction project in a nearby area then the noise level can increase for that area and then based on noise reduction techniques it can also show which technique is impactful in those conditions.

Data Analysis is also a great tool for Noise Mapping. This Noise Mapping procedure involves analyzing a large amount of data on the noise level. And then after studying trends and patterns, high noise level areas and potential sources can be identified. This can help to take measures to reduce Noise levels and prioritize areas for action.

Noise Mapping Software

There are many noise mapping software available in the market. Here are some of the popular ones:

  • CadnaA: This is the most popular among all. This has features to add a virtual model of the area and simulate noises in different conditions. This is widely preferred by researchers, government agencies, etc.
  • SoundPLAN: It allows to creation a detailed map and perform various analyses. This is popular with environmental consultants and government agencies
  • IMMI: This is noise modeling software that can simulate noise levels at airports, traffic and implant noises, etc.
  • NoiSee: This is a good tool to create detailed noise maps using data gathered from Noise sensors and computer models
  • Norsonic Nor-Map: This has options for indoor and outdoor noise maps.
  • Odeon: This also has features like indoor and outdoor noise mapping. It can simulate noise mapping for complex terrain.
  • AERMOD: Software can be used for air quality and noise quality modeling.
  • INM: This is used by aviation authorities for airport noise mapping
  • SOUNDRISK: Software can be used for environmental noise mapping for noise generated from transportation, industries, wind turbines, etc.
  • SIMUL8 Noise: This is used to simulate noise mapping from sources like industrial facilities, construction sites, transportation, etc.

 

Conclusion:

Managing environmental Noise Pollution is the key advantage of Noise Mapping. It assists in locating the sources of noise pollution and the affected areas, allowing for the effective implementation of noise-reduction measures.

Taking action to minimize noise can also benefit the environment and local populations. A noise map can be used to pinpoint locations where sound barriers can lower noise levels and place restrictions on noisy activities.

As a result, Noise Mapping is making a substantial contribution to the development of a healthier and more sustainable environment.

Koala: A Dialogue Model for Academic Research

  Koala: A Dialogue Model for Academic Research Introduction The accidental leak of the weights associated with Meta AI’s LLM LLaMA has sparked tremendous innovation in the open-source LLM space. Since the furious leak, we have seen models like Alpaca, Vicuna, ChatLlama, and several others expand on the foundations of LLaMA to build innovative conversational agents that match the capabilities of ChatGPT. One of the latest additions to the list is Koala (yes, I know, another animal-named model), a chatbot created by Berkeley AI Research (BAIR) that fine-tunes LLaMA on conversations gathered from the internet. The core goal of Koala is to highlight the balance between mega-large closed-source LLMs and smaller, open-source LLMs. BAIR’s thesis is that smaller models can achieve performance that matches mega models like ChatGPT with a fraction of the cost while also improving in areas such as fine-tuning, transparency, and many others. Koala Koala is a version of LLaMA fine-tu...

  What is FLAN-T5? Artificial Intelligence (AI) has been making strides in recent times, with advancements in Large Language Models (LLMs) and their applications taking much of the credit. One of the most prominent models in this domain is GPT-3, developed by OpenAI. However, it is not the only model making waves. FLAN-T5, developed by Google Research, has been getting a lot of eyes on it as a potential alternative to GPT-3. ·        FLAN stands for “Fine-tuned Language Net”         ·        T-5 stands for “Text-To-Text Transfer Transformer” Back in 2019, Google's first published a paper "Exploring the Limits of Transfer Learning with a Unified Text-to-Text Transformer", introducing a novel where they introduced the original T5 architecture. The pretrained encoder-decoder model worked well on multiple tasks, and particlarly well suited for translation and summarization tasks. In 2022 G...
