  • Monitoring of Sound Pressure Level
    1. INTRODUCTION Noise is one of the main environmental problems of modern life and it is inseparable from human activities, urban and technological growth. National and international standards provide for a minimum of acoustic comfort for coexistence between man and industrial development. That's why a study of noise emission and environmental noise at the PALAGUA - CAIPAL Field was carried out; samples of measurements were taken in specific (punctual) manner to meet the sound pressure level (SPL) with a duration of five minutes per sample/measurement for noise measurements and 15 minutes for ambient or environmental noise in each direction: (north, east, south, west and vertical). The result of these measurements was compared with the maximum permissible noise emission and environmental noise standards stated in Resolution 627 of 2006 Ministry of Environment, Housing, and Territorial Development (MAVDT) and thus it was verified that they comply with environmental regulations in the PALAGUA - CAIPAL Field. 1 INFORME DE LABORATORIO 0860-09-ECO.

    5. Noise pollution 1. Please describe the present situation and development over the last five to ten years in relation to (max. 1,000 words): Within the scope of implementing “Directive 2002/49/EC of the European Parliament and the Council of 25 June 2002, relating to the assessment and management of environmental noise”, the proportion of Hamburg’s population subjected to noise emanations from road, railway and air traffic sources as well as industrial, commercial and port facilities has been determined in terms of the noise indicators L den, for noise levels during the day, evening and night, and L night, for noise levels at night. The assessment was calculated on the basis of national provisional computation methods; namely, the “Provisional computation method for environmental noise on roads – VBUS”, the “Provisional computation method for environmental noise on railways – VBUSch”, the “Provisional computation method for environmental noise at airports – VBUF”, the “Provisional computation method for environmental noise from industry and commercial facilities – VBUI”, and the “Provisional computation method for determining the number of individuals exposed to environmental noise – VBEB”. In terms of the industrial, commercial and port sector, in addition to plants located in the port area, only those industrial or commercial zones with one or more plants as per Appendix 1 of the “European Council Directive 96/61/EC of 24 September 1996 concerning integrated pollution prevention and control” are afforded consideration. The period of reference is 2006. Accordingly, the number of individuals affected is as follows: Affected by L den > Affected by L night > 55 dB(A) 45 dB(A) Road traffic 363600 420900 Rail traffic 56200 38900 (L night > 50 dB(A)) Air traffic 43700 5000 (L night > 50 dB(A)) Industry/commercial 4200 10200 /port facilities In line with the requirements of the EU directive, the analyses are updated at least every 5 years, from which commensurate developments regarding issues of concern can be ascertained.

  • Mobile Applications for Environmental Noise and Soundscape Evaluation
    Mobile applications for environmental noise and soundscape evaluation Radicchi, Antonella1 Institute of City and Regional Planning, Technical University of Berlin Hardenbergstraße 40 a Sekr. B 4 – 10623 Berlin ABSTRACT In the past ten years, in parallel to the development of low-cost digital technology, we witnessed the increasing development of mobile applications deployed as environmental noise and soundscape evaluation tools. Firstly, this paper presents the results of a survey conducted through literature and market review covering the past 10 years, spanning from the release of the first app, Noise Tube, to the more recent ones, such as Hush City. Secondly, it discusses the benefits and challenges of using mobile apps for environmental noise and soundscape projects. In conclusion, considering the release of ISO norms on soundscape, it discusses the possibility to standardize the design and implementation of mobile apps for soundscape research.

INTRODUCTION The interest for the acoustic environment of cities, its impact on human health, well-being and quality of life and its implication on design and policy planning has a rather long history that can be traced back to the anti-noise movements of the late XIX centuries and more recently to the so-called soundscape studies stemming from the research conducted by Michael Southworth in the US and by Murray Schafer in Canada in the late Sixties of the XX century1. In order to study and evaluate the characteristics of the acoustic environment different indicators, tools and methods have been developed in the course of the decades (e.g.

  • Aircraft Noise (Excerpt from the Oakland International Airport Master Plan Update – 2006)
    Aircraft Noise (Excerpt from the Oakland International Airport Master Plan Update – 2006) Background This report presents background information on the characteristics of noise. Noise analyses involve the use of technical terms that are used to describe aviation noise. This section provides an overview of the metrics and methodologies used to assess the effects of noise. Characteristics of Sound Sound Level and Frequency — Sound can be technically described in terms of the sound pressure (amplitude) and frequency (similar to pitch). Sound pressure is a direct measure of the magnitude of a sound without consideration for other factors that may influence its perception. The range of sound pressures that occur in the environment is so large that it is convenient to express these pressures as sound pressure levels on a logarithmic scale that compresses the wide range of sound pressures to a more usable range of numbers. The standard unit of measurement of sound is the Decibel (dB) that describes the pressure of a sound relative to a reference pressure. The frequency (pitch) of a sound is expressed as Hertz (Hz) or cycles per second. The normal audible frequency for young adults is 20 Hz to 20,000 Hz. Community noise, including aircraft and motor vehicles, typically ranges between 50 Hz and 5,000 Hz. The human ear is not equally sensitive to all frequencies, with some frequencies judged to be louder for a given signal than others. See Figure 6.2. As a result of this, various methods of frequency weighting have been developed. The most common weighting is the A-weighted noise curve (dBA).

  • Noise Induced Hearing Loss: an Occupational Medicine Perspective Emily Z
    Noise induced hearing loss: An occupational medicine perspective Emily Z. Stucken MD Michigan Ear Institute Robert S. Hong MD, PhD Michigan Ear Institute Corresponding author: Robert S. Hong MD, PhD Michigan Ear Institute 30055 Northwestern Highway, Suite #101 Farmington Hills, MI 48334 Phone (248) 865-4444 Abstract Purpose of review: Up to 30 million workers in the United States are exposed to potentially detrimental levels of noise. While reliable medications for minimizing or reversing noise induced hearing loss (NIHL) are not currently available, NIHL is entirely preventable. The purpose of this article is to review the epidemiology and pathophysiology of occupational NIHL. We will focus on at-risk populations and discuss prevention programs. Current prevention programs focus on reduction of inner ear damage by minimizing environmental noise production and through the use of personal hearing protective devices. Recent findings: Noise induced hearing loss is the result of a complex interaction between environmental factors and patient factors, both genetic and acquired. The effects of noise exposure are specific to an individual. Trials are currently underway evaluating the role of antioxidants in protection from, and even reversal of, NIHL. Summary: Occupational NIHL is the most prevalent occupational disease in the United States. Occupational noise exposures may contribute to temporary or permanent threshold shifts, though even temporary threshold shifts may predispose an individual to eventual permanent hearing loss. Noise prevention programs are paramount in reducing hearing loss as a result of occupational exposures. Key words: occupational noise induced hearing loss, occupational noise exposure, hearing protection programs Introduction Hearing loss is the most widespread disability in Westernized society.
