ENGINEERING ACOUSTICS NOISE AND VIBRATION CONTROL A masterful introduction to
the theory of acoustics along with methods for the control of noise and vibration In …

Aiming at the severe aerodynamic noise generated by the rotor of rotorcrafts, a global active
noise control method is proposed based on near-field acoustic holography (NAH) and …

Conventional active control of road noise inside a vehicle cabin generally uses a pure
feedforward control system with the conventional filtered-x least mean square (FXLMS) …

Vibration control in mechanical equipments is an important problem where unwanted
vibrations are vanish or at least diminished. In this paper, free vibration active control of the …

This paper presents the acoustic performance of a novel approach for the passive adaptive
control of tonal noise radiated from subsonic fans. Tonal noise originates from non-uniform …

Noise, vibration, and harshness (NVH) has been an important factor in the development of
modern motor vehicles since the 1980s. One of the challenges is the control of low …

This paper addresses the problem of absolute stability of Lurie system with interval time-
varying delay. The delay range is divided into two equal segments and an appropriate …

A multi-channel active control system has been applied to the reduction of free-field tonal
noise from a small axial cooling fan, typical of those used in personal computers and other …

Fans are widely used in industry for heat dissipation or airflow production. It is achieved by
driving a motor of fan to rotate a number of blades. Most industrial fans can be categorized …

Noise sources in an axial flow fan can be divided into fluctuating axial thrust forces and
circumferential drag forces. For the popular design of a seven-blade rotor driven by a motor …
