Summary: This paper investigates an experimental assessment of an active noise control system for cabin seat headrests, which uses two loudspeakers on both sides of the passenger's head to create a quiet zone around the passenger's ears. Real-time experimentation shows that the system can achieve approximately 20 dB sound attenuation in laboratory conditions.

Summary: The heat transfer capacity in the cabin under low air pressure was investigated in this study. The results showed that the convective heat transfer coefficient (CHTC) increased in natural convection and was higher in forced convection. Correlation equations for calculating CHTC were proposed, which will guide the design of the cabin thermal environment.

Summary: This study investigated the impact of higher recirculation air rates in aircraft cabins on passengers' health and well-being, and the role of occupancy in this. The results showed that passengers in half-occupied cabins had minimal reactions to increased recirculation air rates, while passengers in fully occupied cabins reported higher sleepiness and stress reactions when the recirculation air rate was high.

Summary: This paper reviews the studies on airliner cabin air environment published since 2000, discussing the challenges and opportunities in studying and improving cabin air environment. Current environmental control systems have not effectively prevented airborne transmission of infectious diseases, but there are technologies available to improve air quality and thermal comfort for designing a better cabin air environment.

Summary: This study found high concentrations of ultrafine particles (UFP) at Heathrow Airport in London, exceeding the exposure limits set by the World Health Organization (WHO). Departing aircraft, particularly larger ones, were found to have the highest UFP emission rates. The number of passengers carried also influenced emission rates per passenger. Calculated emission rates were higher than literature values due to the inclusion of condensable particles in the measurements. The study suggests that UFP concentrations beyond the airport boundary may also be of concern, and assessing population exposure near airports will become increasingly important in the future.

Summary: With the expansion of Beijing's metro system and the increasing number of passengers, it is important to study the indoor environment and passenger comfort in metro stations. This study measured the thermal environment and air quality in the transfer spaces of the top seven transfer stations with the highest passenger flow in Beijing. The results showed that the thermal environment and air quality experienced by passengers changed dynamically during the transfer process, and passengers' subjective feelings of comfort were influenced by psychological factors.

Summary: The rapidly growing vehicle population is a crucial contributor to severe air pollution and public health issues, particularly in urban areas where vehicles are important sources of air pollutants. Limited studies have focused on the variability in in-vehicle concentrations of traffic-related air pollutants and the impact of filtration devices. Results indicate that using high-efficiency cabin air filters can significantly improve PM2.5 filtration efficiency, enhancing in-cabin air quality and reducing health risks for drivers.

Summary: This paper presents the research results on humidity in a passenger car cabin equipped with an air cooling system in the summer season in north-eastern Poland. The study showed that the operation of the cooling system significantly reduced the relative humidity of the air inside the car cabin. The paper also proposed a model of moisture content in the car cabin, which can be used for automatic regulation of car ventilation.

Summary: The survey results show that mechanical ventilation with heat recovery is commonly used in new low-energy residences in Europe, but there are still countries that use other types of ventilation due to tradition, national legislation, climatic conditions, and cost reasons. The main barriers against mechanical ventilation include high capital cost, space requirements, and duct routing.

Summary: The study reviewed 47 documents on volatile organic compounds (VOCs) measurements in commercial aircraft, finding that most VOCs were below permissible levels, with benzene slightly higher. The concentrations of semi-volatile organic compounds and other pollutants did not exceed standards in buildings, but average NO2 concentration was slightly elevated. Additionally, ozone concentration was below the recommended limit, outdoor air supply rate exceeded minimum requirement for commercial aircraft, carbon dioxide concentration was within permitted levels, and temperature and humidity were generally within recommended ranges for comfort.

Summary: A four-week-long field intervention experiment was conducted to investigate the effects of different ventilation rates on sleep quality and cognitive performance in bedrooms. The study found that lower ventilation rates resulted in significantly less deep sleep, more light sleep, and more awakenings. Additionally, a clear difference in deep sleep duration was observed between high and low ventilation rate conditions. However, no differences in cognitive performance were observed between the different ventilation conditions. These findings highlight the importance of proper ventilation control for optimal sleep quality.
