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 ...
Copper Leader Head at Penn's Quadrangle, Philadelphia 1894 Copper Leader at Shofuso Japanese House and Garden in Philadelphia. The purpose of a leader head is to help transfer excess water from the roof onto downspouts, thus preventing the gutters from overflowing and water washing over the walls, which is a common occurrence in areas susceptible to heavy rain cycles.
Sound isolation: Noise isolation is isolating noise to prevent it from transferring out of one area, using barriers like deadening materials to trap sound and vibrational energy. Example: In home and office construction, many builders place sound-control barriers (such as fiberglass batting ) in walls to deaden the transmission of noise through ...
The Noise Pollution and Abatement Act of 1972 is a statute of the United States initiating a federal program of regulating noise pollution with the intent of ...
A washout is the sudden erosion of soft soil or other support surfaces by a gush of water, usually occurring during a heavy downpour of rain (a flash flood) or other stream flooding. These downpours may occur locally in a thunderstorm or over a large area, such as following the landfall of a tropical cyclone .
Harsh noise wall features noises layered together to form a static sound. Harsh noise wall musician Sam McKinlay, also known as The Rita, considered the genre as "the purification of the Japanese harsh noise scene into a more refined crunch, which crystallizes the tonal qualities of distortion in a slow moving minimalistic texture."
Some teams have built stadiums with a roof to protect the field, either as a domed stadium or with a retractable roof.Despite this, the Houston Astros, who played at the Houston Astrodome for 35 years and currently play at the retractable roof-equipped Daikin Park, had a rainout at the Astrodome on June 15, 1976 due to intense flooding in the Houston area.
