The problem of acoustic noise is becoming increasingly serious with the growing use of
industrial and medical equipment, appliances, and consumer electronics. Active noise …

An active structure is an engineering structure containing sensors and actuators that, when
active, modify the response of the structure to its environment. Research into active structural …

Urban noise pollution is an omnipresent but often neglected threat to public health that must
be addressed urgently. Passive noise control measures, which are less effective at reducing …

This textbook is an introduction to the dynamics of active structures and to the feedback
control of lightly damped flexible structures; the emphasis is placed on basic issues and …

Active control of sound and vibration is a relatively new and fast growing field of research
and application. The numbers of papers published on the subject have been more than …

Controlling the level of noise in electrical motors is critical to overall system performance.
However, predicting noise of an electrical motor is more difficult and less accurate than for …

Flexible mechanical systems experience undesirable vibration in response to environmental
and operational forces. The very existence of vibrations can limit the accuracy of sensitive …

Controllability and observability are structural properties that carry information useful for
structural testing and control, yet they are not fully utilized by structural engineers. The …

Active noise control (ANC) technology is increasingly ubiquitous in wearable audio devices,
or hearables. Owing to its low computational complexity, high robustness, and exemplary …

The performance is investigated of a multichannel feedforward headrest system for the
active control of interior road noise around a listener's ears in a vehicle cabin. An active …
