New Who Guidelines for Community Noise

Abstract: This important document replaces the 1980 Environmental Health Criteria No.12 – Noise. It is destined to become widely used and quoted in relation to environmental noise problems. All who have even...

Prediction of Blast Induced Air Overpressure in Opencast Mine

Abstract: Blasting is still considered to be the most economical technique for rock excavation and displacement either on the surface or underground. The explosive energy, which fractures the rockmass is not...

Annoyance due to single and combined sound exposure from railway and road traffic

Abstract: Environmental noise is a growing and well recognized health problem. However, in many cases people are exposed not to a single noise source - for example, road, railway, or aircraft noise - but to a combination of noise exposures and there is only limited knowledge of the effects on health of exposure to combined noise sources. A socio-acoustic survey among 1953 persons aged 18-75 years was conducted in residential areas exposed to railway and road traffic noise with sound levels ranging from LAeq,24h 45-72 dB in a municipality east of Gothenburg, Sweden. The objectives were to assess various adverse health effects, including annoyance, and to elucidate the impact of exposure to single and combined noise sources. In areas exposed to both railway and road traffic, the proportion annoyed by the total traffic sound environment (total annoyance) was significantly higher than in areas with one dominant noise source rail or road traffic with the same total sound exposure (LAeq,24h,tot). This interaction effect ...

Low-Frequency Airborne Sound Transmission through Single Partitions in Buildings

Abstract: The low-frequency (20–250 Hz) airborne sound transmission of single partitions is investigated. Three theoretical models are used for the prediction: an infinite plate model, a baffled plate model and a room-plate-room model. The calculation models are verified by detailed comparisons with experimental results obtained in the laboratory. A parametric study is carried out to examine the influence of the dimensions of the room and the partition. The results demonstrate the strong modal behaviour of the low-frequency sound transmission. As a result, the low-frequency sound insulation depends not only on the properties of the test wall, but also on the geometry and the dimensions of the room-wall-room system.
