  • The Auditory & Non-Auditory Effects of Noise Pollution:An Occupational Health Study

    1. Introduction: The present study was planned as a prospective, longitudinal and panel-type of a study with the documentation of the health effects of noise exposure as its primary objective. Noise as a health hazard has been studied extensively in the last decade and a substantial amount of dose-response information on NIHL and its risk factors has been documented. However most of these studies ...


  • Noise Measurement

    Definitions Threshold and criterion levels The threshold level is the A-weighted sound level at which a personal noise dosimeter begins to integrate noise into a measured exposure. For example, if the threshold level on a sound level meter is set at 80 decibels (dB), it will capture and integrate into the computation of dose all noise in the employee's hearing zone that equals or exceeds 80 dB. ...


  • Environmental Noise

    Introduction The ability to hear sounds is a sensory function vital for human survival and communication. However, not all sounds are wanted. 'Unwanted sounds', for which the term 'noise' is normally used, often have their origin in human activities (mainly transport, industry and households). This article addresses environmental noise ­ also referred to in the scientific literature as ...

    The program window is a XY-plane (parallel to the land surface). A noise source is represented by a small square. In the Status bar at the bottom, we have X and Y coordinate values in meters and data on our environmental system. Point the mouse where you want in the program window and the X and Y values will be shown in the status bar at the bottom. On the left bottom corner, two different text ...

  • Noise 101: What is Equivalent Continuous Sound Level (Leq)?

    For anyone that is measuring sound, you’ve probably come across the term Leq or Equivalent Continuous Sound Level. But what is it and how can it help us when measuring noise with a sound level meter? Setting the Scene Imagine you work on a busy construction site that is operating all day. You have diggers, cranes, trucks and other ...

  • Good practice guide on noise exposure and potential health effects

    The Expert Panel on Noise (EPoN) is a working group that supports the European Environment Agency and European Commission with the implementation and development of an effective noise policy for Europe. The group aims to build upon tasks delivered by previous working groups, particularly regarding Directive 2002/49/EC relating to the assessment and management of environmental noise. This good ...

  • What is a Data Logging Sound Level Meter?

    Looking to buy a sound level meter? You’ll probably see the term “data logging sound level meter” quite frequently. But what exactly is a data logging sound level meter and what does it mean for your noise measurements? Sound level meters have come a long way since Cirrus starting manufacturing their own models in the 1970s. The advances in computing technology has made it far ...
