Active noise control (ANC) is an effective way for reducing the noise level in electroacoustic
or electromechanical systems. Since its first introduction in 1936, this approach has been …

Active sound profiling (ASP) is gaining ever-increasing attention owing to its powerful ability
to balance the sound pressure levels of certain frequency points or frequency bands of …

The feedforward active noise control (FF ANC) technique has been widely used to cancel
the broadband noise in many practical applications. However, it fails to cope with the …

The feedforward hybrid active noise control (HANC) system combines the strengths of the
narrowband ANC (NANC) system and the broadband ANC (BANC) system. Taking this …

This paper proposed a local active control method for the reduction of road noise inside a
vehicle cabin. A multichannel simplified hybrid active noise control (sHANC) system was first …

The study explores the creation of 3D printed sound cancelling waveguides that can be
customised for selected frequencies as a function of geometry. The potential for attenuation …

An optimal strategy is derived for robust performance of feedforward and feedback noise
controllers in active noise control systems with a bounded narrowband disturbance. The …

Excavator interior noise is composed of the engine order narrowband noise and the
impulsive broadband noise caused by working device. In situations where only narrowband …

The conventional hybrid active noise control (HANC) system adopts the standard filtered-x
least mean square (FxLMS) algorithm to adapt its control filters. However, the constant step …

This paper proposed a hybrid active noise control (HANC) system combined with virtual
sensing technique. The Remote Microphone Technique (RMT) method was established in …
