Sound redirection: One of the obvious ways to reduce the received sound level of an observer is to place the observer out of the path of the highest amplitude sounds. For example, in the area around a jet engine , the sound power levels can be expected to be largest (i.e., loudest) directly in line with the jet's exhaust.
Sound baffles on the wall of a recording studio. A sound baffle is a construction or device which reduces the strength (level) of airborne sound. Sound baffles are a fundamental tool of noise mitigation, the practice of minimizing noise pollution or reverberation. An important type of sound baffle is the noise barrier constructed along highways to
Using a combination of sound absorption materials, arrays of microphones and speakers, and a digital processor, a restaurant operator can use a tablet computer to selectively control noise levels at different places in the restaurant: the microphone arrays pick up sound and send it to the digital processor, which controls the speakers to output ...
A pair of headphones being tested inside an anechoic chamber for soundproofing. Soundproofing is any means of impeding sound propagation.There are several methods employed including increasing the distance between the source and receiver, decoupling, using noise barriers to reflect or absorb the energy of the sound waves, using damping structures such as sound baffles for absorption, or using ...
The mechanism by which anechoic chambers minimize the reflection of sound waves impinging onto their walls is as follows: In the included figure, an incident sound wave I is about to impinge onto a wall of an anechoic chamber. This wall is composed of a series of wedges W with height H.
PALERMO — One of the two kindergarteners injured in a Northern California school shooting in early December may not regain the use of his legs, the family told CBS Sacramento on Thursday.
The sound tube in Melbourne, Australia, designed to reduce roadway noise without detracting from the area's aesthetics.. A noise barrier (also called a soundwall, noise wall, sound berm, sound barrier, or acoustical barrier) is an exterior structure designed to protect inhabitants of sensitive land use areas from noise pollution.
The family of a 20-year-old man is speaking out after he was found dead at the bottom of a hotel elevator shaft in Turkey while reportedly on his first vacation with his girlfriend.
