This paper presents a novel and advanced remotely controlled laboratory for conducting Active Noise Control (ANC), acoustic and Digital Signal Processing (DSP) experiments. The laboratory facility, recently developed by Blekinge Institute of Technology (B... see more

The difference in geographical altitudes in tropical environment not only causes variations in climate and environment leading to influences on thermal comfort, but also effects on noise propagation variation. This study proposes the site barrier optimiza... see more

Noise control is an environmental problem of first magnitude nowadays. In this work, we present a new concept of acoustic screen designed to control the specific noise generated by transport infrastructures, based on new materials called sonic crystals. T... see more

Assessing the acoustical performance of building floor systems relies on the impact source to be utilized and on the type of floor cover used. Besides that, a reliable assessment should consider the listeners’ judgments of the sounds transmitted through f... see more

This study aims to determine (1) the level of noise in the area around Juanda Airport, (2) the perception of the community in the area around Juanda Airport about the comfort of life with noise, and (3) public perception of the discourse on implementing e... see more

This study aims to determine and evaluate the level of noise in the southern area of Universitas Negeri Padang (UNP) Kampus Air Tawar conducted at 23 points of measurement with 16 outside outdoor points and 7 indoor measurement points. Method of measureme... see more

This paper offers a concise survey of the most commonly used feedback loops for atomic force microscopes. In addition it proposes feedback control loops in order to minimize the effect of thermal noise on measurements of weak forces, and to improve the ma... see more

Environmental noise from transportation or industrial infrastructure typically has a broad frequency range. Different sources may have disparate acoustical characteristics, which may in turn affect noise annoyance. However, knowledge of the relative contr... see more
