Survey Results

Aircraft noise can disturb the sleep of residents living near airports. To investigate potential effects of aircraft noise on sleep, recruitment surveys for a pilot field study were mailed to households around Atlanta International Airport. Survey items included questions about sleep quality, sleep disturbance by noise, noise annoyance, coping behaviors, and health. Of 3159 deliverable surveys, 319 were returned (10.1%). Calculated outdoor nighttime aircraft noise (Lnight) was significantly associated with lower sleep quality (poor or fair; odds ratio (OR) = 1.04/decibel (dB); p < 0.05), trouble falling asleep within 30 min ≥1/week (OR = 1.06/dB; p < 0.01), and trouble sleeping due to awakenings ≥1/week (OR = 1.04/dB; p < 0.05). Lnight was also associated with increased prevalence of being highly sleep disturbed (OR = 1.15/dB; p < 0.0001) and highly annoyed (OR = 1.17/dB; p < 0.0001) by aircraft noise. Furthermore Lnight was associated with several coping behaviors. Residents were more likely to report often or always closing their windows (OR = 1.05/dB; p < 0.01), consuming alcohol (OR = 1.10/dB; p < 0.05), using television (OR = 1.05/dB; p < 0.05) and using music (OR = 1.07/dB; p < 0.05) as sleep aids. There was no significant relationship between Lnight and self-reported general health or likelihood of self-reported diagnosis of sleep disorders, heart disease, hypertension or diabetes. Evidence of self-reported adverse effects of aircraft noise on sleep found in this pilot study warrant further investigation in larger, more representative subject cohorts.

Noise Impacts

Advanced operational flight procedures that utilize modifications to thrust, airspeed, altitude, and configuration can be implemented to mitigate noise impacts for communities surrounding airports. Evaluating and designing such procedures requires accurate modeling of the aircraft performance, source noise, and atmospheric propagation of the source noise to the ground. Modeling frameworks to assess advanced procedures have been developed but must be validated to ensure their results are reasonable. This paper presents validation of such noise models using a network of ground noise monitoring data at Seattle-Tacoma International airport and ADS-B operational radar flight profiles from the OpenSky database. Modeled noise from operational flights of several aircraft types are shown to be consistent with noise monitor data when reasonable flap settings and atmospheric corrections for the actual weather at the time of flight are used. Discrepancies that exist between the modeled and measured noise results are identified to determine where current noise modeling methods must be improved to accurately represent all relevant noise sources.

The objective of this research is to measure the market share generated by commercial passenger transport airlines that operate direct international routes to and from El Dorado International Airport during the study period 2017-2019, as well as to identify the size of airlines' offer and the market leader, and observing its behavior; considering this airport as the main and most important one in Colombia, as well as cataloged and awarded as one of the best airports in South America by the criteria of the recognized and significant Skytrax awards of the aviation industry; Likewise, this work handles a qualitative-quantitative, exploratory and descriptive bibliographic approach based on the synthetic and deductive-inductive methods applied in the process for obtaining the results and revealed in the analysis presented about the market share reflected by the studied airlines, through the quantitative data collected about the direct international routes handled by each one of them, the size of the market and its evolution throughout the study period.

Zusammenfassung. Die Beziehung zwischen kognitiven Defiziten und Schlafstörungen depressiver Patienten wurde bisher wenig untersucht. Stationär behandelte depressive Patienten beantworteten Fragebögen zur Depressivität und Schlafqualität (Pittsburgh Sleep Quality Inventory, PSQI), gefolgt von neuropsychologischen Untersuchungen zu attentional-exekutiven Funktionsleistungen (Trail Making Test: TMT-A, TMT-B) an Tag 1 (abends) und Tag 2 (morgens). Patienten mit schweren Schlafstörungen (PSQI > 10, n = 8) erbrachten gegenüber Patienten mit maximal moderat ausgeprägten Schlafstörungen (PSQI ≤ 10, n = 8) signifikant geringere Leistungen im Rahmen des TMT-A und TMT-B. Signifikante positive Korrelationen zwischen dem Globalwert des PSQI und der TMT-B-Bearbeitungszeit blieben auch unter statistischer Berücksichtigung von Kovariaten erhalten. Diese Ergebnisse unterstreichen die enge Beziehung zwischen kognitiven Dysfunktionen und Schlafstörungen bei depressiven Patienten. Mögliche therapeutische Implikationen werden diskutiert.
