A visit to New York''s cacophonous Union Square Station with sound designer Joel Beckerman, who shares his ideas for improving the aural
However, for subway station structures with complex joints and construction processes, the calculation cost of the numerical simulation is high, and the efficiency is low. To address these
Abstract To investigate the impact of subway station design on platform noise levels. Observational. Continuous A-weighted decibel (dBA) sound levels were recorded in 20 New York City subway
In this study, comprehensive measurement was conducted on the noise environment on the platforms during operational hours at four distinct types of subway stations within an urban metro network.
The subjective perceptions of passengers are intricately linked to the noise levels in subway stations of urban rail transit systems.
While traditional junction boxes were designed primarily for basic electrical protection, modern junction boxes now include smart features, enhanced materials, and a range of
• Resilient track systems can be considered at aerial stations to reduce radiation of noise from the support structure, and at underground stations with critical adjacencies to reduce vibrations
Subway noise pollution: Examining the causes and effects of excessive noise in subway systems, and exploring potential solutions to mitigate
The sound field in subway stations affects the information propagation for travel and emergencies under normal and urgent conditions. Noise pollution on subway platforms can also
When grouping junction boxes in a project, key factors to consider include proximity to instruments, minimizing cable length, accessibility for maintenance, environmental conditions, and segregation
Fabricating high quality Josephson junction is essential in superconducting qubit circuits. In this letter, high quality tunnel junctions with a low critical current density of ∼32 A/cm 2 were
