IMPROVING CABIN COMFORT: Flight comfort expectations pose new challenges for acoustic development teams

摘要

With the increased competition in air travel and the development of many new Vertical take-off and landing(VTOL) vehicle programs in support of future urban air mobility, providing a quiet cabin is key in the market. However, acoustic requirements are frequently in conflict with the need for lighter and more eco-friendly aircraft Finding the balance between those conflicting requirements is a day-to-day challenge for acoustic engineers. In-flight measurements can be useful to troubleshoot noise issues and design efficient noise control measures for improved cabin comfort.
