The resonance time of a Dead Hall is zero seconds. A Dead Hall is designed to have minimal or no reverberation, meaning sound waves do not reflect off surfaces but are absorbed instead. This results in a very short or ...
The relation between resonance time and volume of a hall has been propounded by Sabine. Sabine’s formula calculates the reverberation time in a room based on its volume and the absorption coefficient of its surfaces. It is crucial in architectural ...
Sonar is mostly used by navigators. Sonar (Sound Navigation and Ranging) is a technology that uses sound waves to detect objects underwater. It is widely employed by navigators, including naval forces, commercial ships, and submarines, to navigate safely, avoid obstacles, ...
The stethoscope works on the principle of reflection of sound. It consists of a chest piece that captures sound waves produced by the heart or lungs. These waves travel through a tube to earpieces, where they are heard by the ...
A person should stand approximately 28 feet from a reflecting plane to hear their echo distinctly. This distance allows for a sufficient time delay between the emission of sound and the return of its reflection, making the echo perceptible to ...
Sound waves produce echo due to reflection. When sound waves encounter a large and hard surface, such as a wall or cliff, they bounce back towards the source instead of passing through or bending (refraction and diffraction). This reflection causes ...
The ball keeps dancing in the water spray at intersections because due to higher velocity of water, pressure becomes higher. The increased velocity of water results in higher pressure, creating a force that propels the ball and causes it to ...
The wall below the dam is made thick because the pressure of the fluid increases with increasing depth. This thick wall is necessary to withstand the increased pressure exerted by the water against it as the depth increases.
The cyclone storm in the Coral Sea brings threats of flash flooding, destructive” winds, and storm tides as Tropical Cyclone Jasper in Australia 2023.
