1. Active Noise Control with Virtual Reference Signals in an FXLMS Algorithm
University essay from KTH/MWL Marcus Wallenberg LaboratorietAbstract : Noise pollution from road traffic is one of the greatest environmental issues in modern day, and the social cost for road traffic noise was estimated to over 16 billion SEK per year in Sweden in2014. Passive or active control methods can be used to reduce the noise. READ MORE

2. Active Noise Control in Forest Machines
University essay from Institutionen för fysikAbstract : Achieving a low noise level is of great interest to the forest machine industry. Traditionally this is obtained by using passive noise reduction, i.e. by using materials for sound isolation and sound absorption. READ MORE

3. Active Noice Reduction headset
University essay from KTH/ReglerteknikAbstract : Conventional (passive) headsets used in propeller aircrafts are reasonably good at attenuating mid to high frequency noise, but fail to achieve good attenuation in the low frequency region (below approximately 300 Hz). Active Noise Reduction (ANR) improves the low frequency attenuation by introducing an anti-noise signal creating destructive interference thus decreasing the residual noise level. READ MORE

4. Active Noise Control of a Forest Machine Cabin
University essay from Institutionen för systemteknikAbstract : Today, a high noise level is considered a problem in many working environments. The main reason is that it contributes to stress and fatigue. Traditional methods using passive noise control is only practicable for high frequencies. As a complement to passive noise control, active noise control (ANC) can be used to reduce low frequency noise. READ MORE

5. Implementation of Adaptive Filter Structures on a Fixed Point Signal Processor for Acoustical Noise Reduction
University essay from Blekinge Tekniska Högskola/Avdelningen för signalbehandlingAbstract : The problem of controlling the noise level in the environment has been the focus of a tremendous amount of research over the years. Active Noise Cancellation (ANC) is one such approach that has been proposed for reduction of steady state noise. READ MORE
