Summary
Urban noise levels near transit-oriented developments (TODs) are influenced by station amenities and neighborhood characteristics. Understanding these soundscape contributors can inform urban planning for better quality of life.
Area of Science:
- Urban planning and environmental science
- Acoustic engineering and transportation studies
Background:
- Investigating urban soundscapes is crucial for understanding city livability.
- Transit-oriented developments (TODs) present unique acoustic environments influenced by transit and urban form.
Purpose of the Study:
- To examine sound levels and identify contributing factors at TOD station and neighborhood levels.
- To analyze the impact of station amenities, socio-demographics, and built environment on urban sound levels.
Main Methods:
- Multilevel analysis modeling sound level likelihood.
- Sound measurements using a Type II SPL meter at Dallas Area Rapid Transit (DART) light rail stations (TOD and non-TOD).
- Sampling over weekdays and weekends across three time intervals.
Main Results:
- Station amenities, built environment, and neighborhood features significantly impact sound levels.
- TODs with more amenities showed greater significance in sound level variations.
- Neighborhoods with dense street grids and facilities had higher sound levels, while higher population/intersection densities reduced them.
Conclusions:
- Urban planning and policy must consider acoustic implications of TOD design and neighborhood characteristics.
- Findings offer insights for creating healthier urban sound environments and improving quality of life.

Whether solid, liquid, or gas, a substance's state depends on the order and arrangement of its particles (atoms, molecules, or ions). Particles in the solid pack closely together, generally in a pattern. The particles vibrate about their fixed positions but do not move or squeeze past their neighbors. In liquids, although the particles are closely spaced, they are randomly arranged. The position of the particles are not fixed—that is, they are free to move past their neighbors to...

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...

02:58Properties of Transition Metals
29.7K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.

01:17Soundness of Cement
543
The soundness of cement refers to the ability of cement paste to retain its volume after setting. Unsound cement can lead to expansion and structural damage due to the presence of free lime, magnesia, and calcium sulfate. Free lime hydrates very slowly, expanding and causing unsoundness, which is difficult to detect because it intercrystallizes with other compounds. Magnesia also reacts with water, forming crystals that can disrupt the cement's structure. Calcium sulfate can create...

01:15Heart Sounds
3.3K
Heart sounds are generated by the turbulence in blood flow due to the closing of heart valves. These sounds are best perceived slightly away from the valves, where the blood flow disseminates the sound.
Auscultation is the process of listening to these internal body sounds using a stethoscope. The heart produces four types of sounds, but only two—S1 and S2—can usually be heard with a stethoscope.
S1, also known as the "lub" sound, is caused by the closure of atrioventricular (A-V)...

Korotkoff sounds are the specific sounds heard while measuring blood pressure using a sphygmomanometer, typically with a stethoscope or a Doppler device. They are named after Russian physician Nikolai Korotkov, who first described them in 1905. These sounds correspond to turbulent blood flow in the artery as the blood pressure cuff is gradually released after inflation.
