A NASA picture taken through the window in the sidewall of the 8- by 6-foot supersonic wind tunnel at NASA's Glenn Research Center shows a 1.79 percent scale model of a future concept supersonic aircraft built by the Boeing Company in this handout released on April 25, 2013. In recent tests, researchers evaluated the performance of air inlets mounted on top of the model to see how changing the amount of airflow at supersonic speeds through the inlet affected performance. The inlet on the pilot's right side (top inlet in this side view) is larger because it contains a remote-controlled device through which the flow of air could be changed. The work is part of ongoing research in NASA's Aeronautics Research Mission Directorate to address the challenges of making future supersonic flight over land possible. Researchers are testing overall vehicle design and performance options to reduce emissions and noise, and identifying whether the volume of sonic booms can be reduced to a level that leads to a reversal of the current ruling that prohibits commercial supersonic flight over land.

Muscat – The Environment Authority has announced a new regulation aimed at controlling noise levels in public spaces to safeguard human health and protect living beings from the harmful effects of excessive noise pollution.
The regulation introduces comprehensive definitions and provisions that specify acceptable noise levels in various zones, including residential, tourist, recreational, commercial, and industrial areas, as well as alongside main and express roads.
The new framework outlines the obligations of project owners to ensure compliance with noise limits and establishes technical requirements for monitoring noise levels in public spaces. It also provides for administrative penalties for violations.
Implemented under the provisions of the Environmental Protection and Pollution Control Law and the Public Environment Noise Pollution Control Regulation, the decision sets clear limits and enforcement measures. The regulation aims to reduce the impact of loud sounds from projects and activities that disrupt the environment.
