“…In the field of occupational medicine, several studies claim that low-frequency noise is an agent that interferes with the performance of work tasks [25,[27][28][29] and that low-frequency noise can affect mental and physical health.…”

The Influence of Low-Frequency Noise Pollution on the Quality of Life and Place in Sustainable Cities: A Case Study from Northern Portugal

Discussing urban planning requires rethinking sustainability in cities and building healthy environments. Historically, some aspects of advancing the urban way of life have not been considered important in city planning. This is particularly the case where technological advances have led to conflicting land use, as with the installation of power poles and building electrical substations near residential areas. This research aims to discuss and rethink sustainability in cities, focusing on the environmental impact of low-frequency noise and electromagnetic radiation on human health. It presents data from a case study in an urban space in northern Portugal, and focuses on four guiding questions: Can power poles and power lines cause noise? Do power poles and power lines cause discomfort? Do power poles and power lines cause discomfort due to noise? Can power poles and power lines affect human health? To answer these questions, we undertook research between 2014 and 2015 that was comprised of two approaches. The first approach consisted of evaluating the noise of nine points divided into two groups "near the source" (e.g., up to 50 m from power poles) and "away from the source" (e.g., more than 250 m away from the source). In the second approach, noise levels were measured for 72 h in houses located up to 20 m from the source. The groups consist of residents living within the distance range specified for each group. The measurement values were compared with OPEN ACCESSSustainability 2015, 7 13921 the proposed criteria for assessing low-frequency noise using the DEFRA Guidance (University of Salford). In the first approach, the noise caused discomfort, regardless of the group. In the second approach, the noise had fluctuating characteristics, which led us to conclude that the noise caused discomfort.

“…Borredon and Nathie (1973) exposed men to pure tones of infrasound (again at 130 dB), and found that some subjects exhibited decreased performance on some tasks, while other subjects actually exhibited improvements in performance. Kyriakides and Leventhall (1977) reported no statistically significant effects on task performance in subjects exposed to a band of infrasound extending from 2 to 15 Hz at 115 dB. The authors speculated that performance on tasks of longer durations could potentially be affected by infrasound; there has, however, been no further evidence to support this claim.…”

“…The levels used in these experiments are considerably higher than the exposure levels of people in their homes, arising from environmental, traffic, industrial and other sources. There is an indication of performance decrements at high levels of low frequency noise (Kyriakides and Leventhall, 1977;Mohr et al, 1965;Persson-Waye et al, 1997) …”

The paper reviews perception of low frequency noise (LFN) and the responses of people to LFN. Sometimes, when there are complaints of LFN and its effects, a specific noise cannot be measured. The possibilities are considered for development of enhanced sensitivity, for alternative (non-aural) receptors at very low frequencies and for false perceptions. The way in which we measure LFN may contribute to the problems. INTRODUCTIONThere is considerable misunderstanding about low frequency noise and infrasound Some of this is due to misleading presentations by scientists 30 or 40 years ago (Gavreau, 1968;Gavreau et al., 1966), which were interpreted selectively by the media in order to give eye-catching news stories. A succession of "reinterpretations" over a period of five or six years led infrasound and low frequency noise to be described in popular texts as a cause of death, whilst also possessing the ability to knock down buildings. (Watson, 1974). This aura of mystery and danger still persists today, deep in the minds of many people, where it waits for a trigger to bring it to the surface. The most recent trigger has been wind turbines.Although we know a great deal about low frequency noise, there are aspects which we cannot yet explain. We know about how people hear low frequency noise and that some have a low tolerance to it. We believe that low frequency noise may, in general, be more annoying than higher frequency noise, but do not know why this is so. We do not know why some people complain of a low frequency noise which cannot be measured separately from the background noise.It is also possible that there are subtle effects of low frequency noise on the body, which we do not yet understand.
