“…This, along with other related work implies that noise at low frequencies is considered more annoying by individuals (Broner, 1978;Berglund et al, 1996;Pawlaczyk-Luszczynska, 2010). Moreover, related research has also found that low frequency noise has a greater degree of 'unpleasantness' than noise in the A-weighted frequency bands (Inukai et al, 2000;Nakamura and Inukai, 1998). Exposure to low frequency noise also causes sleep disturbance (Leventhall, 2003) and its associated secondary effects with the WHO (Berglund et al, 1999) noting that it 'can disturb rest and sleep even at low sound levels'.…”

The World Health Organisation has recently acknowledged that contrary to the trend for other environmental stressors, noise exposure is increasing in Europe. However, little research has been conducted on environmental noise exposure to handling activity at shipping ports. This paper reports on research examining the extent of noise exposure for residents within the vicinity of Dublin Port, Ireland using the nation's largest port terminal as a proxy for port noise. In order to assess the level of exposure in the area, long-term measurements were undertaken at the most exposed residential façade for a period of 45 days to determine the extent of night-time exposure was above levels recommended by the World Health Organisation. The indicators L90, Leq and LMax were used to determine exposure levels. The results show that exposure is above night-time guideline limits set down by the WHO and is above Irish levels for triggering a mitigation response and highlight the extent to which port noise can be a significant environmental stressor. The research also investigated the extent of low-frequency noise (which is associated with greater health issues) from night-time port handling activity and found a significant low-frequency component indicating the negative health issues that might arise from port noise exposure more generally. We also undertook semi-structured interviews with residents to qualitatively assess the self-reported impact of prolonged night-time noise exposure for local residents.

“…These adverse psychological effects can be induced even by low-level low-frequency noise in living environments 8,9) and they are expected to be more prevalent in working environments where high-level low-frequency noises are generated [10][11][12] . Inukai et al 13) reported that the slopes of the equalunpleasantness level contours are very similar to those of the equal-loudness level contours. This finding indicates that hearing sensation plays an important role in perceiving unpleasantness or annoyance of persons exposed to lowfrequency noise, despite the low audibility of the noise.…”

A Study on the Relationship between Subjective Unpleasantness and Body Surface Vibrations Induced by High-level Low-frequency Pure Tones

et al. 2005

Human body surface vibrations induced by high-level low-frequency pure tones were measured at the chest and the abdomen. At the same time, the subject rated the unpleasantness that he had just perceived during the exposure to low-frequency noise stimulus. Examining the relationship between the measured vibration and the rating score of the unpleasantness revealed that the unpleasantness was in close correlation with the vibration acceleration level (VAL) of the vibration measured. Taking previous results into account, this finding suggests that noise-induced vibrations primarily induce vibratory sensations and through the vibratory sensation or together with some other factors, secondarily contribute to the unpleasantness. The present results suggest that in evaluating high-level low-frequency noise, the effect of vibration should be taken into account.

“…There is of course, a wide range of possible stimuli, which experimenters have chosen according to their experience of what is required. (Adam, 1999;Andresen and Moller,1984;Broner and Leventhall, 1978b;Broner and Leventhall, 1984;Broner and Leventhall,1985;Goldstein,1994;Goldstein and Kjellberg, 1985;Inukai et al, 2000;Kjellberg and Goldstein, 1985;Kjellberg et al, 1984;Moller,1987;Nakamura and Inukai,1998;Persson-Waye,1985;Persson and Bjorkman,1988;Poulsen, 2002;Poulsen, 2003a;Poulsen, 2003b;Poulsen and Mortensen, 2002). Some of the laboratory studies have used recordings of real noises as stimuli, whilst others have worked with recordings of the actual noises as experienced by subjects in their own work places or homes.…”

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.
