“…This standard takes into account the factors influencing the acoustic performance of openspace offices such as furniture layout, acoustic absorption and background noise. It does not take into account, however, how the employees themselves perceive their workplace noise environment, while studies on the assessment of noise in general have demonstrated that the perceived intensity only accounted for 20% (Job 1996) to 25% (Landström et al 1995) of the variance in noise annoyance felt by the individuals.…”

Noise effect on comfort in open-space offices: development of an assessment questionnaire

It is currently accepted that noise is one of the most important annoyance factors in open-space offices. However, noise levels measured in open spaces of the tertiary sector rarely exceed 65 dB(A). It, therefore, appears necessary to develop a tool that can be used to assess the noise environment of these offices and identify the parameters to be taken into consideration when assessing the noise annoyance. This article presents a questionnaire to be filled by people working in such environment, and a case study in different open plan offices. The majority of the 237 respondents consider that the ambient noise level in their environment is high and that intelligible conversations between their colleagues represent the main source of noise annoyance. This annoyance was significantly correlated with their evaluation of sound intensity, which could not be represented by A-weighted level measurements.

“…A common conclusion in previous studies [5,6,7,8] is that noise levels are generally high in olive oil mills and create risk for workers, who generally work more than 8 hours a day for about two months during olive season. In a study which everal olive oil mills in Italy [9], a country known for its wide spread of olive mills and large production of olive oil, noise levels were recorded in different inside each mill to find out the average noise level.…”

Abstract:This study is concerned mainly with high noise produced by automated olive mills and its negative impact on human health. This study looks at what caused this problem such as the application of building codes concerning user exposure to noise and protective measures for workers. Long working period exposure to high noise, particularly mill workers, causes health and ear illness. Noise levels are measured in several olive mills in Jordan, recorded data was analyzed and findings indicated that noise level is higher than the maximum noise limits allowed by the Jordanian code. This study concludes design solutions and legislative procedures to improve noise control in olive mills.

“…Therefore, only people characterised by high sensitivity to low-frequency sound and living in quite rural locations can be affected. Nevertheless, even though a number of such people is relatively small, these cause quite specific physiological and legal aspects related to individual perception of lowfrequency noise [24], in particular the increased annoyance of tonal components [25]. We did not touch these aspects in the present work, concentrating on physical mechanisms of the low-frequency noise.…”
