Acoustic system for use in an interior of an aircraft, aircraft seat, aircraft bed, and aircraft

An acoustic system for use in an interior of an aircraft, including:

• an upper body support section for use with at least one of an aircraft seat or an aircraft bed, the upper body support section defining at least one resting surface configured for at least a portion of an upper body of a user to rest against;
• and
• at least one actuator, wherein the at least one actuator is embedded at least partially within the upper body support section and configured to generate soundwaves,
• wherein the upper body support section includes at least one excitable surface which the at least one actuator can excite to generate soundwaves in the upper body support section,
• wherein the acoustic system is configured to provide a minimum degree of active noise reduction to at least one sound in an external space adjacent to the upper body support section and within a distance of 5 cm to 40 cm from the at least one resting surface of the upper body support section;
• wherein the acoustic system further includes, for the purpose of providing the active noise reduction,
• at least one sound sensing device configured to sense the at least one sound in the interior of the aircraft within a distance of 40 cm from the at least one resting surface, and
• at least one controller configured to receive information related to the sensed at least one sound and to control the at least one actuator to generate at least one soundwave to at least partially reduce the sensed at least one sound based on the information.
