1. 1. Active Noise Control of an Insulated Box Fan using Feedforward and Feedback Control

   Magister-uppsats, Blekinge Tekniska Högskola/Sektionen för ingenjörsvetenskap

   Författare :Muddala Suryanarayana Murthy; Muhammad Haris; [2010]
   Nyckelord :Active Noise control; Adaptive signal processing; Fan; noise reduction; ventilation system; feedforward control; feedback control;

   Sammanfattning : In recent years, the active noise control methods are more attractive in reducing unwanted noise. Salient features of active control methods over passive control methods drive more attention to active noise control systems for reduction of low frequency noise. LÄS MER

3. 2. Active Noise Control of a Radial Fan

   Magister-uppsats, Blekinge Tekniska Högskola/Avdelningen för signalbehandling

   Författare :Muddala Suryanarayana Murthy; Mohamed Gafar Ahmed Elnourani; [2009]
   Nyckelord :Active Noise control; Adaptive signal processing; Fan; noise reduction; ventilation system;

   Sammanfattning : This thesis work aims at investigating the use of an active noise control (ANC) system on a radial fan. This was done by studying the fan structure and its potential working environment (the ducts). This includes measuring the sound levels on several positions and select suitable positions to apply the ANC system. LÄS MER
